- the present invention aims to solve the new technical problem consisting in the supply of a solution allowing surgical treatment of hyperthermia tissues, in particular the prostate, in a precise manner, these tissues being accessible by a lumen while allowing to provoke, in progress or at the end of heat treatment, a dilation of this lumen, and in particular of the urethra, in the case of treatment of the prostate.
- the present invention solves this technical problem in an extremely simple, semi-invasive manner, that is to say by using the natural cavities of the body, or lumens, usable on an industrial scale.
- the present invention provides an apparatus for the surgical treatment of hyperthermia tissues, preferably the prostate, accessible by a lumen, of the type comprising a probe introduced into said lumen, comprising heating means, characterized in that it comprises means temporarily or intermittently increasing the outside diameter of the probe, arranged relative to the probe, so as to allow dilation of said lumen, at least in the tissues to be treated, when desired.
- the means for temporarily or intermittently increasing the outside diameter of the probe comprise at least one dilatation balloon, comprising means for filling and / or emptying the dilatation balloon.
- the means for temporarily or intermittently increasing the outside diameter of the probe are arranged on said probe outside thereof.
- the means for filling and / or emptying the expansion balloon are connected to, or form part of, a cooling circuit of the probe.
- the expansion balloon is made of a flexible material, capable of withstanding, without bursting, high pressures, up to 20 bars, for example in latex reinforced or not.
- the probe comprises means for locking in position in said lumen.
- these blocking means comprise at least one blocking balloon, for example made of latex, surrounding the probe, which can be expanded, to block the probe in position, by supplying inflation fluid, by means for supplying the blocking balloon, preferably independent, of the aforementioned expansion means.
- the above-mentioned dilatation balloon extends longitudinally outside the probe over a distance sufficient to cause dilation of the lumen, at least in the tissues to be treated by hyperthermia, in particular the prostate.
- the tissues to be treated are formed by the prostate, the aforementioned probe is a urethral probe and the lumen is the urethra.
- the aforementioned heating means comprise a microwave generation device disposed in a central orifice of said probe.
- This microwave generator device is advantageously that described in document FR-88 15126, and comprises a metal cable coaxial with the probe, surrounded by an insulating sheath over part of its length, said cable comprising at least one stripped portion of microwave emission, preferably disposed at an intermediate or distal level of the probe.
- the aforementioned expansion balloon is advantageously located at the level of the heating means.
- the device according to the invention makes it possible to cause, during or at the end of heat treatment, a dilation of the lumen, and therefore a compression of neighboring tissues. This significantly improves thermotherapy.
- dilation of the urethra during or at the end of heat treatment results in compression of the surrounding prostatic and peri-vesical tissues, which improves unexpected, urination problems, usually allowing to eliminate them.
- the single figure, attached, shows a schematic view in partial section.
- a surgical treatment apparatus of tissues by hyperthermia is represented by the general reference number 500.
- the apparatus includes a probe 520 to be introduced into a lumen of a patient, providing access to tissues to be destroyed by hyperthermia.
- the 520 probe is a urethral probe inserted into the urethra up to the level of the prostate.
- This probe is preferably essentially of the type described in the applicant's previous patent application FR-88 15126, which is incorporated here by reference and to which a person skilled in the art can refer.
- this probe 520 is equipped with heating means 518, arranged in a central orifice 519, preferably comprising a microwave generation device as described in document FR-88 15126.
- this microwave generator device comprises a metal cable coaxial with the probe, surrounded by a insulating sheath over part of its length, said cable comprising at least one stripped part of microwave emission, preferably disposed at an intermediate or distal level of the probe.
- this device is characterized in that it comprises means (600) for temporarily or intermittently increasing the outside diameter of the probe, arranged relative to the probe so as to allow expansion of the lumen (not shown ), at least on the tissue to be treated, when desired.
- the means 600 are arranged at least at the level of the prostate.
- the means 600 comprise at least one balloon 610 for expansion, comprising means 620 for filling and / or emptying the balloon, preferably under high pressure, and in particular between approximately 2 and approximately 20 bars, and preferably between 5 and 7 bars which constitute advantageous pressure values to limit the cost of manufacturing and operating the device while ensuring in particular good longevity.
- the means 600 are available on the probe 520 outside thereof, as shown.
- the means 620 for filling and / or emptying the expansion balloon 610 are preferably connected to, or form part of, a cooling circuit for the probe, and in particular that described in document FR-88 15126.
- the expansion balloon is made of a flexible material, capable of withstanding, without bursting, at high pressures, up to 20 bars, for example in latex reinforced or not.
- the dilation balloon 610 is shown in the expanded state.
- This embodiment is an integral part of the invention and therefore of the present description. It will be observed that in the dilated state, this balloon has essentially a cylindrical shape, with an outside diameter which depends on the characteristics of the constituent material and internal pressure values. It is thus understood that it is possible for the practitioner to adjust within wide limits the final value of the external diameter of the expansion balloon 610, which is particularly advantageous.
- the probe 520 comprises blocking means 630 in position in the lumen.
- These blocking means comprise at least one blocking balloon, 632 for example made of latex, surrounding the probe, which can be inflated, to block the probe in position, by supplying inflation fluid by means 633 for supplying the balloon. blocking 632, preferably independent of the expansion means 630.
- the dilation balloon 610 extends longitudinally externally to the probe 520 over a distance sufficient to cause dilation of the lumen, at least at the level of the tissues to be treated by hyperthermia, in particular the prostate.
- other blocking means 640 similar to the blocking means 22, FIG. 2 and 3 or 126, FIG. 4 of document FR-88 15126 can be arranged.
- These other blocking means include advantageously a balloon which is placed within the framework of the treatment of the prostate, inside the bladder, as described in the document FR-88 15126.
- the expansion balloon 610 is placed between the locking means 630 and 640, at an intermediate level, advantageously at least in part at the level of the hyperthermia heating means, generally at the level of the micro generation device. -waves.
- the invention therefore makes it possible to dilate the lumen, preferably the urethra within the framework of the treatment of the prostate, during or at the end of heat treatment, thereby ensuring compression of the neighboring tissues as indicated above.
- the invention also covers a method of therapeutic treatment, comprising the heating of tissues to be treated, by heating means advantageously comprising the use of a device for generating microwaves arranged in an emitting probe capable of being introduced into a lumen giving access to the vicinity of said tissues, characterized in that said lumen is expanded during or at the end of heat treatment of said tissues.
- this expansion is carried out by providing the probe equipped with at least one expansion balloon.
- this method is applied to the treatment of the prostate by hyperthermia, the emitting probe being a urethral probe introduced into the urethra up to the level of the prostate.
- the dilation balloon is then provided on the probe outside it to be arranged at least partly at the level of the prostate during treatment.
- the invention naturally includes all the means constituting technical equivalents of the means described as well as their various combinations.
