- each of Figs. 1-3 shows a different conceptual design for a system.

- System 200 can be generally the same as system 100, except that intrabody portion 202 has less complex and/or less circuitry than intrabody portion 102, with the difference being compensated for by added functionality in external portion 204 (e.g., vs. external portion 104). For example, in one embodiment, all of the components except for circuitry 112 and 126 are the same. In some embodiments, a single external portion 204 is designed to work with either of internal portions 102 and 102.

- transmitter 120 may act as or be provided along with a receiver.
- system 100 and system 200 are often a matter of degree. It is noted that a system with a different tradeoff may be used as well, for example, a system where most of the processing and/or control are provided in the intrabody portion and only a small part and/or only power provided by the external portion. In some cases, communication bandwidth limitations between the intrabody and external components may dictate which distribution of functionalities to use.

- commands e.g., "sense”, "stimulate using program #1
- intrabody portion 102 For system 204, optionally, no commands are sent.

In one example, a patient is told to use the blue “pill” first and if this fails, to use the "pink” pill. Unlike medication, however, circuitry 126 can be set up to prevent inadvertent over dosing, by avoiding stimulating until acceptable to do so.
- circuitry can delay application of a stimulation (or sensing) for another reason, for example, to ensure it is done while sleeping (e.g., using an accelerometer sensor to detect sleep) and/or after exercise or eating, at a time delay (e.g., using an internal clock), in synchronization with oral dosing (e.g., requiring patient input or input from a cellular telephone, e.g., with a cellular telephone acting as a user interface to external portion 304) and/or according to a physiological state of the patent and/or target tissue.

- Fig. 14 is a schematic of a system 1400 using one or more accounts to manage a device functionality, in accordance with some exemplary embodiments of the invention.
- An implant 1402 for example an IPG such as an ICD or a pacemaker can communicate with a charger or data communicator 1404 having an account 1406 thereon.
- implant 1402 is physically able to provide various functionalities, however, there is a logic lock which prevents one or more functionalities from being applied, absent permission, which may be supplied by account 1406.
- an account e.g., additional or alternative
- data communicator 1404 is in the form of a sticker which is attached near the implant to allow it to operate.
- data communicator 1404 is a smart card which may be swiped at the implant (or at an antenna near a body surface, associated with the implant).
- communicator 1404 is activatable.
- swiping at the implant transfers an account amount to the implant.
- a charger or other controller 1404 is provided, which may be loaded using one or more payment elements 1408 (e.g., smart cards).
- a payment element includes one or more account 1410 thereon.
- Such an account may be general or may be linked to a particular type of functionality and/or may include a fixed or a variable amount of units therein.
- payment elements 1408 and 1408' are examples of data carrying components which may carry data, such as device settings, other than or in addition to authorizations.
- implant 1402 is controlled by charger/controller 1404 and the payment elements are used only to recharge it.
- system 1400 includes accounts for one or more of power, data upload, data download, program, data logging, diagnosis functions and/or therapy functions.
- power is stored at the implanted device, though its activation is external (e.g., through a sticker including credit).
- credit may be reloaded from a wireless card or a new sticker may be purchased.
- an implantable device is sold at some nominal price, well below its normal selling price.
- the patient or third-party payer - for example, insurance
- the therapy would be sold through stickers.
- system 1400 and in particular implant 1402 provide at least life saving functionality even if the accounts are empty.
- implant 1402 is a CRT-D system and if the accounts are empty, the CRT therapy (which generally less life-saving and more related to quality of life) is disabled or reduced in quantity and/or quality, but ICD function (which is life saving) is maintained.
- applying a therapy by the implant in response to data/commands from an external control component may or may not involve actual application. Rather, the authorizations may be utilized to allow the implant to apply a therapy and/or certain therapy parameters if needed. In some embodiments, for example relating to payment, authorization may be consumed only if the implant is actually active. In some embodiments, however, even the act of allowing the implant to act, absent any acting, consumes at least some authorization(s).
- the system is used in a pay- per-use mode.
- each use of the system e.g., time unit, number of therapy sessions applied, number of events treated (e.g., meals, exercise, pain, symptom occurrence) and/or amount of data collected
- reduces the account balance e.g., of a general account or a functionality-associated account.
- the functionality is blocked and/or reduced in amount and/or quality application (e.g., one or more of the therapy being applied with/for less time, reduced power efficiency, increased side effects, reduced intensity, reduced spatial coverage (e.g., fewer painful areas treated), reduced accuracy, reduced selectivity/resolution, reduced logging, slower response and/or reduced UI functionality and/or fewer available parameters).
- amount and/or quality application e.g., one or more of the therapy being applied with/for less time, reduced power efficiency, increased side effects, reduced intensity, reduced spatial coverage (e.g., fewer painful areas treated), reduced accuracy, reduced selectivity/resolution, reduced logging, slower response and/or reduced UI functionality and/or fewer available parameters.
- the accounting is performed in an external controller and that controller (possibly in the form of a simple sticker) sends control (or authorization) signals to implant 1402, optionally in response to requests for authorization by implant 1402.
- controller possibly in the form of a simple sticker
- implant 1402 is sold at a nominal price, possibly well below its normal selling price.
- the patient or third-party payer - for example, insurance
- the payment is on a periodic basis (e.g. once a month) and used to allow continuous therapy.
- the therapy is sold through stickers, whereby a unit of credit is debited each time the implant is used.
- the presence of credit on the sticker verifies to the implant that therapy can be delivered. As time passes and therapy is delivered, the credit availability on the sticker decreases. Once credit reaches zero or some other threshold, the implantable device stops delivering therapy until a new sticker with credit is applied to the skin.
- the sticker is identified and causes an account on the implant to be updated (a single time per sticker id).
- This account is then optionally decreased as authorizations are consumed.
- the amount of credit in an account or the existence of an account is used as a "status of the account”.
- a charger or other controller is provided to allow a user to read the balance on a sticker.
- NFC or other cell-phone linking technologies are used and allow a user to read a balance on the sticker.
- a sticker is good for a time period (e.g., a certain month), and expires when the calendar month is over. In some cases, the sticker is for a certain therapy or time of day or trigger and does not expire.
- the sticker includes a chemical which slowly oxidizes or otherwise changes when exposed to ambient and a user can see this change and determine when the sticker is expired.
- an electrochemical reaction in which electrical current through a part of the component causes or encourages chemical change, for example, oxidation or decomposition or color change.
- chemical change for example, oxidation or decomposition or color change.
- the color change is parented to give a meaningful signal such as the word "expired”. Additional details which may be implemented in some embodiments of the invention, are described below.
- the sticker is electronically active, for example, including counter or a clock which deactivates the card and/or reduces functionality that the card can authorize, over time or uses.
- the card includes a user interface, such as a button, whereby a user can selectively activate implant 1402 by pressing the button or charge implant 1402 with one or more credits thereby.
- the card includes a feedback mechanism, such as a speaker, which generates audible feedback on the credit transfer process, optionally notifying "empty” if pressing the button does not transfer any credit to the implant.
- an account in implant 1402 is directly loaded by a payment element 1408 or a cellphone (or other portable or wired electronic device) with NFC or other short-range wireless communication protocol.
- a card 1408 is sold (or provided by insurance) to the patient.
- Card 1408 is placed in proximity to implant 1402 (or charger/controller/programmer 1404, in some embodiments), and implant 1402 reads its internal information (e.g., account 1410) to reload credit within the implant 1402 (e.g., an account 1406' therein).
- the same operation would deduct the credit from the card.
- the constant presence of card 1408 (or a sticker) is not needed to achieve the desired pay-per-use or controlled usage performance of the implant 1402.
- card 1408 carries one or more encoded one time tokens, and implant 1402 does not allow reuse of a token, so card 1408 can be read only.
- card 1408 is a short-term activated card, for example, including battery with short life or including component damaged by exposure to ambient. This allows a card to be inactive, be activated (e.g., by opening a seal) so as to charge implant 1402 or charger 1404 with uses and then expire so that the card is not reused on other implants.
- a card 1408 when it first communicates with an implant is paired with that implant, for example, by writing an implant code in a non-erasable memory of the card. Thereafter, any transmission of the card includes the implant code and data from the card. This may prevent use of the card (or other control component, such as a sticker) with more than one implant.
- a particular use where it may be desirable to have a card work with two (or more) implants is where a patient has multiple implants and a single card is used to provide data and/or instructions for a plurality of such implants and/or provide same information (e.g., patient weight) to two or more implants.
- a card may include a limited number of implant code storage locations, optionally with a limitation that it only work with implants that are different from each other in type.
- a same card may include pairs of implant codes and implant data/commands and send the data/commands according to an implant code received by the card.
- a card or other control component sends data in a tagged format, such as XML, so as to allow implants to read the data and recognize relevant for their operation.
- a card or other control component sends data in a tagged format, such as XML, so as to allow implants to read the data and recognize relevant for their operation.
- This may also allow more general programming or programming a card with multiple alternatives. This may be useful, for example, if a card is designated as used or a particular therapy, but it may be unknown at the time of card preparation which of a plurality of different implant models and/or abilities it will be used with. Loading such a card with multiple alternatives may simplify sales and/or distribution thereof.
- the accounts are substantially unlimited in capacity.
- one or more of the accounts are limited.
- the implant may be limited in number of uses or time of activation which it can store. This may be used to enforce periodic checkups and/or other contact with a health care provider (e.g., once a month or quarterly or annually).
- a user can unload functionalities (e.g., account credits) from an implant 1402 to a charger 1404, for example, for reimbursement or for transfer to a different implant, optionally in a different patient.
- functionalities e.g., account credits
- implant 1402 has a sleep mode, whereby the implant stops looking for stickers to read after a period where no external control component is provided. For example, such reading may stop after 1-7 days, 1-3 weeks or 1-2 months or intermediate periods. This may save battery power.
- the implant may be woken up again to, for example periodically, listen for external control signals.
- such waking up is by using strong external magnetic field which interacts with a reed (or other) switch in the implant or by using a programmer device.
- a device resetting sticker is provided to reset the device, instead of using a magnetic field, if desired.
- any programming requires two stickers, one which is an authentication sticker (e.g., associated with by a medical caregiver and digitally signed) and one or more for parameters.
- a similar paired use of stickers may be used by a user (e.g., required by the implant), for example, for set up or for particular implant activations and/or for all implant activations.
- a plurality of authorization levels may exist, for example, some device settings being authorizeable by a nurse and some by a doctor and some by a specialist.
- Fig. 14 also shows an authentication and/or authorization server 1422, provided in some embodiments of the invention.
- this server is used by charger 1404 (or indirectly by implant 1402) to verify the authenticity of an attempt to provide instructions and/or units to the accounts. For example, when a payment element 1408 is used to charge account 1406, charger 1404 may check with authentication server 1422 if the value provided by payment element 1408 is still valid.
- Fig. 14 shows an optional billing server 1420, in accordance with some embodiments of the invention.
- billing server 1420 is used by a care provider such as a HMO, to help regulate treatment to a patient.
- Billing server maybe used to dispense usage authorizations. In this sense billing server 1420 may act like a pharmacy.
- billing server 1420 can dispense limited life "treatment", which can prevent overusage or delayed usage of treatment by a patient. Similarly, underusage may be reported to billing server 1420.
- a separate treatment server 1424 is used to track treatment and determine treatment dispensing logic.
- the various servers can be combined as a single server or the tasks carried out by them otherwise divided up, in some embodiments of the invention.
- one or more of the above described servers is configured (e.g., using an expert system or a rule based system or a table of options) to generate a set of stickers suitable for situation comprising a patient, an implant, a disease state, a quality of care, a budget and/or a desired result.
- a set of stickers suitable for situation comprising a patient, an implant, a disease state, a quality of care, a budget and/or a desired result.
- such generation is in response to a request by a doctor.
- the server issues instructions to program or assemble authorization codes and/or stickers or other control components, optionally marked for and/or pre-coded for a particular patient, implant and/or medical health provider.
- a potential advantage of using accounts to control authorization is that direct communication with implant 1402 is not needed, while control over its usage can be obtained.
- a payment element needs to be loaded with input from implant 1402 if it is to be recharged.
- loading is automatic by charger 1404.
- a payment element 1408 e.g., in a sticker
- control of the implant is by controlling the charger 1404.
- charger 1404 is limited (or blocked) in its ability to charge implant 1402 absent sufficient credit in one or more accounts 1406 thereof.
- the amount of charge which can be passed may be limited by such credit, requiring more frequent charging or disabling certain implant functions based on lack of sufficient charge.
- limits may be place on other functionality of charger 1404, such as ability to read data or ability to send programming.
- Fig. 15 is a flowchart 1500 of a method of using system 1400, in accordance with some exemplary embodiments of the invention.

- the account is low enough (or zero) that one or more functionalities is optionally blocked and/or reduced in amount and/or quality.
- the device moves to a low-functioning state where various machine functions are changed. For example, when a functionality is blocked, logic of applying other functionalities may be changed.
- implant 1402 optionally continues to operate in a low-functionality state, optionally one which maintains all life-saving therapies of implant 1402 and/or which prevents disease progression.
- one or more accounts in implant 1402 or a controller thereof are optionally updated (e.g., increased), for example, using a payment element 1408 or a direct connection to a server.
- Implant 1402 or charger 1404 may authenticate the update using a remote server, for example, if the update is in the form of digitally signed tokens or in the form of one time codes.
- the device operation mode optionally changes, for example, to a high-functioning state.
- implant 1402 is a CRT device, which is optionally programmed in an off mode. Applying a sticker (optionally batter powered) to the skin near implant 1402 or an antenna thereof causes implant 1402 to go to an on-mode. If an account mechanism is used, implant 1402 may be in a high-functioning on state. Once the account is empty, the device may return to a low-functioning state, rather than an off-state. Optionally, to go to an off-state, the sticker may need to be removed, or an "off-control" sticker applied. This may prevent inadvertent turning off of implant 1402.
- sticker-based mode changes may be useful for other reasons.
- a device mode may be changed based on health consideration, with different stickers providing different operation logic and/or parameters.
- a device which is malfunctioning or having undesired effects may be switched off or its functionality changed, using an appropriate sticker.
- a device which causes nausea may be temporarily turned off for a meal using a sticker.
- a pain control device is switched off during exercise or sleeping (or taking of medication), where pain may be less sensed, to avoid side effects.

- the logic of selecting which functionality is active and/or the details of operation of the implant are provided in the implant, with the sticker or other external control only providing authorization and/or accounting services.
- a sticker or controller may determine device parameters and/or if or when to apply a therapy and/or analyze sensed signals to decide on therapy.
- a sticker is used for temporary pain control (e.g., 15 minutes, an hour, 6 hours or intermediate time periods).
- the device is activated for 5-10 minutes (or some other sub-60 minute period and stays off absent user indication (e.g., via a sticker) that more relief is needed.
- attaching a long pain relief sticker may cause additional pain relief stimulation of, for example, 30 minutes, 4 hours or more.
- implanted stimulation systems need not be for stimulation.
- an implanted system may be used for monitoring (e.g., blood pressure or glucose level monitoring).
- an implant may act as a valve or as a pump (e.g., LVAD).

- a sticker is used to release a drug dose and/or to set a desired release schedule.
- the device is activated to apply CRT therapy as needed to control HF (Heart Failure), responsive to decompensation (e.g. fluid accumulation) detected by a sensor on the sticker (e.g., an impedance sensor).
- CRT therapy for example, when HF symptoms are not detected, requires extra payment/authorization.
- additional therapy for example, responsive to detected heavy breathing, requires extra payment/authorization.
- the signal is applied in response to an eating event.
- eating detection is by the sticker for example using abdominal electrical sensing or impedance measurement or by sensing swallowing motions using an accelerometer or tensile sensor on a suitably placed sticker or by user input via the sticker, by the act of attaching a sticker or by a user swallowing a pill- shaped control component before, during or after eating.
- signals are applied periodically to control hunger.
- a sticker may set how quickly the device will stimulate the stomach after sensing food consumption - a shorter amount of time may cause the person to eat less at each intake due to an earlier sensation of satiety.
- a different sticker may also control the food consumption detection threshold -> lower threshold means fewer false negatives but more false positives.
- the user experiments with stickers at home (optionally provided as a kit) to detect a desirable threshold setting.
- Such a set of "calibration stickers” may be provided for other devices and parameter sets.
- the implantable device remembers the last used sticker set-derived parameters until reprogrammed (e.g., using different stickers),
- PA Implantable Pulmonary Artery
- a sticker could control the accuracy and frequency at which the signals are recorded.
- a patient uses a sticker to "signal" his activity during the day as this could affect the observed changes in the pressures recorded.
- this will allow a health care professional who reviews the logs to detect abnormalities more accurately than without such stickers indicating the type of activity. For example, if the patient is resting he should use the sleeping sticker. The choice of sticker is then recorded on the implantable device during the recording session. Then the data is transmitted for review and the reviewer may notice some fluctuations in PA pressure which are out of the ordinary for a patient who is resting.

- stickers are coordinated with other treatment, like surgery, physical therapy or medication.
- a sticker is marked with a timing indicator, such as "two hours before therapy” or "two days after surgery”.
- stickers are associated (and provide different implant activity) with various daily activities, for example: sleep, eat, office work, drive, exercise, sexual activity.
- a LVAD decreases pumping capacity on low exercise (when an appropriate sticker is applied).

- an allocation of budget resources is determined.
- the allocation can include baseline treatment amount, threshold for applying baseline treatment and a number and/or degree of event-related treatments for acute events.
- the allocation may define a threshold of disease state above which treatment is provided and/or an amount of treatment to provide for different events.
- this allocation is used to calculate an issue a plurality of stickers and/or usage codes for the patient, for example, on a monthly basis.
- a first therapy is applied, for example a baseline CRT therapy.
- this therapy is applied independent of budget, for example, being included in a basic treatment package.
- a request is made to apply a second therapy, for example, CCM, for example in response to an increased need in cardiac output, for example exercise.
- the request may be made by the implant (e.g., sensing cardiac output) or by the user (e.g., apply a sticker).
- the determination takes into account health consideration (e.g., a safety rule may prohibit two CCM applications at times that are too close or durations that are too long.
- the determination takes into account available usage codes and does not apply the therapy if such codes are not available or a usage account is empty or near empty.
- the determination takes into account a budget for future needs, to ensure treatment options remain open as predicted. For example, the allocation may include treatment for five events a month, while ten are expected. This means that during the first half of the month no more than five events will be treated and/or that events with a lower severity will not be treated.
- feedback is provided, for example, to the user, indicating if/how therapy is applied.

- the charge for applied treatment depends on one or more of its type, amount and degree.
- the budget allocation takes into account treatment income variations, for example, based on day, month or season. For example, more treatment (e.g., CRT) may be allocated for a harvest season when there is less income uncertainty and less treatment (e.g., only ICD) in the winter, when the harvest and income therefrom are unknown.
- more treatment e.g., CRT
- less treatment e.g., only ICD
- the charge for treatment is inversely related to need. For example, if the implant senses a greater need (e.g., a greater need for cardiac output), then the price for treatment goes down.
- a sticker is used for overriding.
- an implant may be programmed to treated only above a certain threshold and a sticker (e.g., of a limited supply) by applied to override this threshold and treat.

- Some embodiments of the invention provide features which may improve compliance, especially in pay-per use settings and/or where stickers are used to activate a device.
- One or more of the following features is optionally provided in some embodiments of the invention. It is noted that one or more of these features can be implanted without a sticker or usage code mechanism, for example, by allowing communication between an implant and a server, programmer and/or patient. However, use of stickers and/or pay per use may enhance the usefulness of one or more of these features.
- a first feature of some embodiments of the invention is that positive control by user may be applied. This may help keep the patient aware of ongoing therapy and increase compliance of other treatments. Optionally or alternatively, the fact that a user can control expenditures may allow a user to better match his needs to his budget, rather than avoid treatment out of fear of running out of money.
- a second feature of some embodiments is that a physician can apply treatment (e.g., a sticker), without the patient needing to take an active part (other than not remove the sticker). Such application may last until a next visit.
- treatment e.g., a sticker
- a third feature of some embodiments is that the sticker may be visible, providing a visible reminder to the patient to replace the sticker and/or that therapy has been applied. This may be useful n patients with memory problems.
- color change by the sticker is used as a reminder to replace the sticker.
- a fourth feature of some embodiments is that a physician can "program" the device using a sticker, potentially alleviating the need to use a programmer and making it more likely that the implant will be properly used.
- a fifth feature of some embodiments of the invention is that an implant or other medical device can be programmed with an expected usage pattern and detect hen such pattern is not met.
- the patient can be offered various incentives, starting from psychological incentives and also financial incentives (e.g., reduced cost stickers, increase treatment duration for same price), which may relate to the treatment or be independent thereof (e.g., shopping coupons, reduction in health insurance rates).
- financial incentives e.g., reduced cost stickers, increase treatment duration for same price
- usage is reported to a billing server or health server is noted above.
- incentives are calculated by the implant and/or by a remote server.
- a "coupon" sticker is provided, which a patient can apply to the device to receive special offers.
- a patient may be offered alternative treatment, for example, if side effects are causing lack of compliance.
- the use of stickers makes it easier to instruct a user how to change his treatment (e.g., "use pink stickers instead of green stickers in the morning").
- a sixth feature of some embodiments of the invention is tracking an effect of treatment and/or side effects, for example, using one or more sensors on the sticker and/or one or more sensor in the implant.
- such sensing may be used to detect not only usage but also side effects and/or efficacy.
- detection may be reported to a treatment (or other) server for suggestion of alternative therapy.
- determination is carried out locally, for example, by the implant and/or programmer.
- suggestion is by a physician calling up a patient and suggesting sticker change and/or downloading usage codes to the user (e.g., via cellphone), optionally for loading into a sticker or the implant.
- determinant of danger of disease progression is used to warn patient of the importance of compliance.
- the patient is told both the effect of his non-compliance and the effect of his partial compliance.
- the implant (or other parts of the system) can track the effect of such communication, by assessing which input the patient responds to (by applying sticker) and which not.
- a seventh feature of some embodiments of the invention relates to patient feedback.
- the sticker therapy and/or formulation is selected so as to enhance a user's perception of efficacy.
- the dosage of therapy applied by a sticker is selected so that a patient will notice is effect and/or notice the effect of the sticker being stopped.
- some therapies such as electrical stimulation can have relatively fast effects and/or relatively fast decay of effect.
- sticker based therapy includes a gradual rise or decay, for example, to avoid abrupt shocks to the body.
- sticker-initiated therapy may have a defined ramp-up and/or a defined ramp-down period.
- each such period is, for example, between 1% and 30% of the treatment time, for example, between 5% and 20% or between 2% and 10%.
- the periods are ignored if stickers are applied consecutively.
- the sticker includes an indication of efficacy, for example, heart rate or acceleration, or such indication is sent to a patient's cellular telephone or computer, thereby allowing user to see that applying therapy has a measurable effect.
- the sticker includes the sensor needed to calculate this efficacy (e.g., accelerometer and/or GPS to show distance walked or height climbed before rest), or the sticker receives such indication from the implant.
- the sticker operates without input from the implant, for example using only own sensors.
- An eighth feature of some embodiments of the invention relates to pay-per-result, rather than pay-per-use.
- a user can pay based on an effect of treatment or be provided a refund (full or partial) based on effect. For example, in a HF treatment system, if cardiac output is not increased, then a patient may not pay.
- the above described accounts are not debited or debited less according to a degree of effect detected by the implant, programmer and/or sticker (e.g., depending where sensing is located).
- the implant reports an efficacy of treatment (or a treatment episode mandated by the sticker), for example, by indication of an effect of treatment or a physiological measurement, to the sticker and this data is optionally uploaded back to a billing server to calculate a charge or refund, for example, based on a promised effect.
- the sticker consumes authorizations or refunds thereof based on said uploaded efficacy.
- what is reported is actual operation of the implant, for example, not charging or charging less authorizations when the implant did not provide an active therapy. This may be useful for implants with a consumable, such as a drug eluting implant.
- Such pay per result may encourage patients to use treatment and/or allow implantation as their financial risk is lower.
- a proxy indicator is used.
- a pain treatment device may use heart rate or blood pressure as indicators of stress caused by pain and relived by device.
- a user may be allowed to report efficacy.
- f user reports no efficacy, treatment is blocked. This may prevent or reduce fraudulent reporting.
- performance is evaluated by a third party, for example, laboratory blood tests or a stress test.
- a third party for example, laboratory blood tests or a stress test.
- Such data may be entered into the implant and/or sent to a billing server for determination of payment/refund.
- efficacy is used to control payments between a health care provider and the device provider. For example, more payment if there is more effective treatment and/or lesser side effects.
- a ninth feature of some embodiments of the invention is that payments per use are small, so that a financial risk of a user are reduced, especially if a user can refund unused usage codes (e.g., by allowing such codes to be erased form a sticker connected to the internet).
- an intrabody medical system as described herein includes, in addition to a medical payload and control circuitry programmed to activate the medical payload, receiver circuitry and account memory storing therein at least one value indicating one or more authorizations to activate.
- the account memory is operatively connected to the receiver circuitry to receive such values.
- the control circuitry is configured to activate the medical payload responsive to one or more authorizations from the account memory and thereafter consume at least one authorization, optionally taking into account efficacy thereof.
- a desired efficacy is provided by a sticker, for example, as described herein above, for example, programmed by a doctor, pharmacists and/or remote server.
- compositions, method or structure may include additional ingredients, steps and/or parts, but only if the additional ingredients, steps and/or parts do not materially alter the basic and novel characteristics of the claimed composition, method or structure.
- a compound or “at least one compound” may include a plurality of compounds, including mixtures thereof.
- range format is merely for convenience and brevity and should not be construed as an inflexible limitation on the scope of the invention. Accordingly, the description of a range should be considered to have specifically disclosed all the possible subranges as well as individual numerical values within that range. For example, description of a range such as from 1 to 6 should be considered to have specifically disclosed subranges such as from 1 to 3, from 1 to 4, from 1 to 5, from 2 to 4, from 2 to 6, from 3 to 6 etc., as well as individual numbers within that range, for example, 1, 2, 3, 4, 5, and 6.
