Definitions
- the present invention relates to a device for placing an implant.
- the related art includes the use of catheters or any other instrument for placing an implant in a vessel of the human or animal body.
- the invention may be used for placing objects in a vessel in the form of implants of the stent type or a vascular occlusion device as presented for example in the document WO-A-02 19 926, or implants of the coil type.
- the invention can also apply to the placing of transparietal occlusion devices for closing an opening in a vessel.
- the term implant therefore applies here in the broad sense.
- the placing of implants in a vessel requires the formation of a transparietal opening (by penetration of the various layers of tissue) to reach the internal lumen of said vessel.
- a dilation instrument comprising a tapered end part able to produce a gradual increase in the diameter of the passage produced in the vascular wall.
- the first step is to introduce a needle through the vascular wall and a guide element, generally in the form of a guide cable the end of which is held in position in the lumen, is positioned.
- the guide cable makes it possible to insert other instruments and to guide them through the opening produced in the vascular wall.
- These instruments generally comprise an introducing element with a central tapered end part enabling the diameter of the parietal opening to be gradually increased.
- This central tapered element is surrounded by an external sheath that ultimately comes to be introduced through the vascular wall after the central tapered part has produced its effect. The latter can then be withdrawn while the external sheath is held in position and used to perform the required surgical action.
- the guide cable can remain in position.
- the tapered part for gradual introduction is implemented in an element internal to the instrument until it arrives at the diameter of the external sheath.
- the internal tapered part encumbers the internal volume of the external sheath throughout part of the operation, which in particular excludes any possibility of the presence of another functional or implantable element (for example a vascular implant) in the internal space of the external sheath, before having finalized insertion.
- another functional or implantable element for example a vascular implant
- WO-A-02 19 926 concerns a vascular occlusion device comprising two expandable members for fixing thereof by abutment on two portions of the wall of the vessel. It furthermore comprises an intermediate part deformable in torsion to a degree adjustable according to the relative positions of the two expandable members so as to create a maximum stricture zone defining a degree of occlusion.
- This document also presents a method of use as well as an appliance for placing this occlusion device.
- the dilation instruments currently known prove to be unsuitable for techniques of the type described in WO-A-02 19 926 in particular because they exclude the presence of a functional element in the internal space thereof before the end of insertion in the vessel.
- a device for delivering a vascular occlusion plug is known from the document U.S. Pat. No. 5,320,639.
- the device comprises a channel in which the plug is inserted, which is placed in contact with a lateral opening in the wall of a vessel.
- the channel may have a tapered and openable end. This device is intended for a specific use of occlusion through the outside of a vascular vessel.
- the present invention has been made to address at least the above problems and/or disadvantages and to provide at least the advantages described below.
- the present invention remedies the drawbacks of the devices known up to the present time.
- it enables gradual insertion, an increase in the diameter of the parietal opening and a centering in a vessel by means of a single external member that also participates in the release of the implant.
- the present invention does not require the encumbering of the internal space of the device since there is no tapered central part to withdraw.
- the internal space of the device is therefore kept free, for the integration in particular, from the start, of an implant in the device. It is thus possible, for example, to offer for sale an instrument fully equipped with the implant to place.
- the invention can provide a first insertion, and be closed again in order to reach another vascular section and to be re-employed therein.
- the invention characteristically comprises a casing with a dilation device fulfilling both a dilation function and a function of holding the implant directly applied at least partially to the internal wall thereof. In this way a compact assembly is produced (fewer superimposed sheaths) facilitating placing while being guidable by a conventional central guide of the guide cable type.
- the casing therefore also serves as a centering member inside the vessel.
- a free space is moreover preserved at the center of the assembly, for example for the passage of an expansion balloon.
- the implant is fully protected during the placing movements.
- the tapered nose of the casing ensures the progressiveness of the release, preventing any “jump” effect normally encountered through the abrupt variation in the diameter of a stent when it is expelled from the housing thereof.
- the present invention concerns a device for placing a vascular implant, comprising:
- the implant comprises an expandable member bearing on the inner wall of the outer casing,
- the translation means comprise an inner sheath mounted so as to slide in the outer casing and pushing the expandable member
- the implant comprises a second hollow expandable member and a hollow intermediate part deformable in torsion,
- the second expandable member bears on the inner wall of the inner sheath
- the inner sheath is mounted slidably and rotatably in the outer casing
- the gripping handle of the inner sheath is situated at the rear of the gripping handle and the outer casing and comprises a removable spacer interposed between said handles so as to maintain the spacing thereof,
- the deployable segments are joined at isolated points along the slots in the closed position of the nose,
- the nose comprises a residual central passage
- the nose has a shape memory so as to be closed by default when the opening means are inactive

- the tapered end makes it possible to effect a channel-type broadening by forcing the gradual separation of the walls or by extension of the separation of the tissues over the penetration area.
- the profile of the dilator also enables the instrument to be self-centered. This type of profile limits the risk of lesion of the internal wall of the vessels, often covered with calcified patches, use for “therapeutic” dilation as effected by the inflation of a balloon with endoprosthesis.
- the pressure exerted on the walls makes it possible to fracture the calcified patches and to hope for an increase in caliber that persists after deflation of the balloon. An incomplete result is supplemented by the placing of an endoprosthesis.
- the document WO-A 02 19 926 presents a special vascular occlusion device comprising two expandable end members and an intermediate part deformable under torsion by modification of the relative angular positions of the two expandable end members.
- the device for placing of the vascular occlusion device indicated in the above document is described. This being the case, this example of use is purely indicative and could not be considered to be a limitation of the application of the present invention.

- the expandable member may be self-expandable or expandable by balloon.
- FIGS. 1 and 2 present in side view and cross-section a placing device according to the invention.
- This device 21 comprises in the front part thereof a device 1 for dilating a vessel. Opposite the dilation device 1 , the placing device 21 comprises a part allowing manipulation by the practitioner.

- the outer casing comprises a distal end formed by a nose 14 with a tapered shape configured to enable insertion in the vessel through the wall thereof.
- the nose 14 is first of all in the default closed position so as to constitute the tapered insertion profile.
- opening means are present to open the nose 14 .
- the nose 14 is equipped with a plurality of slots 16 a, 16 b, 16 c, 16 d implementing a partitioning of the nose 14 into several segments 15 a, 15 b, 15 c, 15 d .
- the segments 15 a, 15 b, 15 c, 15 d thus have a relative freedom of movement enabling the nose 14 to be opened in a movement substantially corresponding to that of the petals of a flower.
- the number of slots 16 a, 16 b, 16 c, 16 d and the length thereof in the longitudinal direction of the device 1 are not limited to the example illustrated.
- the segments 15 a, 15 b, 15 c, 15 d of the nose 14 have a shape memory in order to regain the closed idle position thereof when the opening means are no longer active. It is thus possible to open and close the nose 14 on several occasions, according to the requirements of the practitioner.

- the inner sheath 3 may consist of a substantially cylindrical portion with a circular cross-section. The distal end of the inner sheath is left free while the other end comprises a handle 7 for gripping by the practitioner.
- the invention also comprises a pusher 4 visible in FIG. 10 in a preferred embodiment in which it has a central channel 27 producing a residual passage in the core of the device as well as a handle 12 receiving, in the case depicted, an end valve 22 and a coupling 23 for ancillary connections.
- the pusher 4 is mounted slidably in the internal space of the inner sheath 3 .
- FIGS. 1 and 2 Through this assembly, the configuration illustrated in FIGS. 1 and 2 is arrived at.

- the guide cable 11 is here positioned in the residual central channel 27 of the pusher 4 and its proximal end is associated with a sleeve also allowing manipulation.
- the opening of the nose 14 takes place as follows. From a closed position, appearing for example in FIG. 11 , the practitioner removes the first spacer 8 so as to enable the outer casing 2 to be withdrawn relative to the inner sheath 3 until the handles 6 , 7 are put in abutment. During this withdrawal movement, the distal end of the inner sheath 3 exerts an abutment on the internal wall of the outer casing 2 via an expandable member 24 of the implant 10 . This abutment causes the deployment of the segments 15 a, 15 b, 15 c, 15 d of the nose 14 as is clear from FIG. 14 .
- isolated joins 17 are present over the length of the slots 16 a, 16 b, 16 c, 16 d so as to preserve an adjusted cohesion between the various segments 15 a, 15 b, 15 c, 15 d during the insertion phase.
- These joins 17 are nevertheless designed so as to not to interfere with the deployment of the nose 14 and to make it possible to detach the various segments 15 a, 15 b, 15 c, 15 d through the abutment exerted by the inner sheath 3 when the outer casing 2 is withdrawn.
- Spot welds may serve as joins 17 .
- the implant 10 is positioned in the internal space of the outer casing 2 before the start of the operation. More precisely, the distal expandable member 24 is held by the internal wall of the outer casing 2 . At the rear, another expandable member 25 is held in position against the internal wall of the inner sheath 3 .
- the rear end of the expandable member 24 is put in abutment on the front end of the inner sheath 3 .
- the rear end of the expandable member 25 is put in abutment against the distal end of the pusher 4 . This configuration is shown clearly in FIG. 11 .
- the practitioner inserts the nose 14 through the vascular wall until it arrives at the required implantation.
- the spacer 8 is removed, which enables the practitioner to withdraw the outer casing 2 relative to the inner sheath 3 , by means of the handle 6 .
- This movement is illustrated in FIG. 12 . It gives rise to an abutment of the expandable member 24 and inner sheath 3 on the internal wall of the outer casing 2 able to deploy the nose 14 by separation of the various segments 15 a, 15 b, 15 c, 15 d.
- FIG. 14 shows the expansion of the expandable member 24 once released can be noted.
- the other expandable member 25 is also held inside the inner sheath 3 .
- the practitioner uses the handle 7 to modify the angular position thereof.
- the inner sheath 3 it is necessary for the inner sheath 3 to have a possibility of rotational movement on the longitudinal axis of the device.
- it is advantageous to provide means for adjusting the angular position of the inner sheath 3 for example in the form of a reference 19 situated on the handle 7 opposite a plurality of graduations 20 formed on the external surface of the pusher 4 at a point visible to the user.
- the assembly consisting of the outer casing 2 and the inner sheath 3 is withdrawn by a rearward translation movement exerted at the handle 6 in order to move it closer to the handle 12 as far as abutment.

Abstract
Provided is an implant placement device that includes an envelope that contains an implant with a first auto-expandable element expandable in a radial direction, a nose at a distal end of the envelope, a sheath that confines a portion of the implant therein and restricts expansion of a second auto-expandable element of the implant, and a plunger. The sheath moves within the envelope in a longitudinal direction perpendicular to the radial direction and the plunger moves in the longitudinal direction within the sheath with the implant positioned between an end of the plunger and the nose, to discharge the implant from the device at a desired position. The sheath slides in the longitudinal direction towards the nose to bring the first auto-expandable element in contact with an interior of the plurality of slots, thereby opening the nose.
Description

No. 10/553,007, which was filed in the U.S. Patent and Trademark Office on Aug. 7, 2006, which is a National Phase Entry of International Application No. PCT/FRO4/50118, which was filed on Mar. 22, 2004, and claims priority to French Patent Application Serial No. 0350096, filed on Apr. 4, 2003, the entire disclosure of each of which is incorporated herein by reference.
- 1. Field of the Invention
- The present invention relates to a device for placing an implant.
- 2. Description of the Related Art
- In general, the related art includes the use of catheters or any other instrument for placing an implant in a vessel of the human or animal body.
- The invention may be used for placing objects in a vessel in the form of implants of the stent type or a vascular occlusion device as presented for example in the document WO-A-02 19 926, or implants of the coil type.
- The invention can also apply to the placing of transparietal occlusion devices for closing an opening in a vessel. The term implant therefore applies here in the broad sense.
- The placing of implants in a vessel requires the formation of a transparietal opening (by penetration of the various layers of tissue) to reach the internal lumen of said vessel.
- In general, a dilation instrument is used for this purpose, comprising a tapered end part able to produce a gradual increase in the diameter of the passage produced in the vascular wall.
- In general, the first step is to introduce a needle through the vascular wall and a guide element, generally in the form of a guide cable the end of which is held in position in the lumen, is positioned. The guide cable makes it possible to insert other instruments and to guide them through the opening produced in the vascular wall. These instruments generally comprise an introducing element with a central tapered end part enabling the diameter of the parietal opening to be gradually increased. This central tapered element is surrounded by an external sheath that ultimately comes to be introduced through the vascular wall after the central tapered part has produced its effect. The latter can then be withdrawn while the external sheath is held in position and used to perform the required surgical action.
- For example, it is through the residual external sheath that it is possible to effect the placing of a vascular implant. During these operations, the guide cable can remain in position.
- The usual technique described above has many drawbacks.
- First, the tapered part for gradual introduction is implemented in an element internal to the instrument until it arrives at the diameter of the external sheath. In this context, the internal tapered part encumbers the internal volume of the external sheath throughout part of the operation, which in particular excludes any possibility of the presence of another functional or implantable element (for example a vascular implant) in the internal space of the external sheath, before having finalized insertion.
- Another drawback of current inserters is that there remains a dimension transition zone between the internal tapered element and the external wall of the external sheath: this creates a discontinuity in diameter, which may be detrimental to the continuity of the insertion movement and damage the internal wall of the vessels.
- The aforementioned document WO-
A-02 19 926 concerns a vascular occlusion device comprising two expandable members for fixing thereof by abutment on two portions of the wall of the vessel. It furthermore comprises an intermediate part deformable in torsion to a degree adjustable according to the relative positions of the two expandable members so as to create a maximum stricture zone defining a degree of occlusion. This document also presents a method of use as well as an appliance for placing this occlusion device. - The dilation instruments currently known prove to be unsuitable for techniques of the type described in WO-A-02 19 926 in particular because they exclude the presence of a functional element in the internal space thereof before the end of insertion in the vessel.
- From the document US-A1-2002 0042622, a medical device for interventions of the anastomosis type is known. This device comprises a trocar serving to transfix the wall of a vessel. This trocar, with a tapered and openable end, does however have a highly limited function according to this prior art since it serves only for perforation.
- A device for delivering a vascular occlusion plug is known from the document U.S. Pat. No. 5,320,639. The device comprises a channel in which the plug is inserted, which is placed in contact with a lateral opening in the wall of a vessel. The channel may have a tapered and openable end. This device is intended for a specific use of occlusion through the outside of a vascular vessel.
- The present invention has been made to address at least the above problems and/or disadvantages and to provide at least the advantages described below.
- The present invention remedies the drawbacks of the devices known up to the present time. Thus it enables gradual insertion, an increase in the diameter of the parietal opening and a centering in a vessel by means of a single external member that also participates in the release of the implant.
- The present invention does not require the encumbering of the internal space of the device since there is no tapered central part to withdraw.
- The internal space of the device is therefore kept free, for the integration in particular, from the start, of an implant in the device. It is thus possible, for example, to offer for sale an instrument fully equipped with the implant to place.
- It furthermore proves possible to perform several operations in the vessel during the same surgery: by forming a shape-memory system, the invention can provide a first insertion, and be closed again in order to reach another vascular section and to be re-employed therein.
- The invention characteristically comprises a casing with a dilation device fulfilling both a dilation function and a function of holding the implant directly applied at least partially to the internal wall thereof. In this way a compact assembly is produced (fewer superimposed sheaths) facilitating placing while being guidable by a conventional central guide of the guide cable type.
- The casing therefore also serves as a centering member inside the vessel. A free space is moreover preserved at the center of the assembly, for example for the passage of an expansion balloon.
- It should also be noted that the implant is fully protected during the placing movements. When an expandable member is released, the tapered nose of the casing ensures the progressiveness of the release, preventing any “jump” effect normally encountered through the abrupt variation in the diameter of a stent when it is expelled from the housing thereof.
- Other aims and advantages will emerge during the following description of a preferred embodiment of the invention, which however is not limitative.
- The present invention concerns a device for placing a vascular implant, comprising:
- a device for dilating a vessel with an outer casing and a tapered end part for insertion into the vessel, said end part consisting of a nose formed at the distal end of the outer casing and the dilating device, comprising means for opening the nose with at least two longitudinal slots dividing the nose into several deployable segments in order to open the nose,
- an implant placed in the outer casing, characterized by the fact that
- the implant comprises an expandable member bearing on the inner wall of the outer casing,
- it has means for the translational movement of the implant relative to the outer casing so that the expandable body bears on the inner wall of the nose so as to deploy the segments thereof.
- This device may be presented in advantageous but non-limitative variants indicated below:
- the translation means comprise an inner sheath mounted so as to slide in the outer casing and pushing the expandable member,
- the implant comprises a second hollow expandable member and a hollow intermediate part deformable in torsion,
- the second expandable member bears on the inner wall of the inner sheath,

- The term dilation means, in the context of the invention, both:
- the dilation of a narrowed area by a solid instrument of gradually increasing size. The tapered end makes it possible to effect a channel-type broadening by forcing the gradual separation of the walls or by extension of the separation of the tissues over the penetration area. The profile of the dilator also enables the instrument to be self-centered. This type of profile limits the risk of lesion of the internal wall of the vessels, often covered with calcified patches, use for “therapeutic” dilation as effected by the inflation of a balloon with endoprosthesis. The pressure exerted on the walls makes it possible to fracture the calcified patches and to hope for an increase in caliber that persists after deflation of the balloon. An incomplete result is supplemented by the placing of an endoprosthesis.
- The document WO-A 02 19 926 presents a special vascular occlusion device comprising two expandable end members and an intermediate part deformable under torsion by modification of the relative angular positions of the two expandable end members.
- In the following description, the use of the device according to the invention for placing of the vascular occlusion device indicated in the above document is described. This being the case, this example of use is purely indicative and could not be considered to be a limitation of the application of the present invention. In particular, the device may have an implant of other types, in particular with a single member expandable over the width thereof The expandable member may be self-expandable or expandable by balloon.
-
FIGS. 1 and 2 present in side view and cross-section a placing device according to the invention. Thisdevice 21 comprises in the front part thereof a device 1 for dilating a vessel. Opposite the dilation device 1, the placingdevice 21 comprises a part allowing manipulation by the practitioner. In particular, handles 6, 7 and 12 are formed for gripping. Thehandle 12 may integrate or receive various accessories such as avalve 22 preserving the fluid tightness of the instrument and acoupling 23 for connection of additional tubes. - The various elements constituting the dilation device 1 and the placing
device 21 according to the invention are described below more precisely in the embodiment illustrated. - In this context,
FIG. 3 shows the formation of a guide cable 11 (also referred to as a guide wire) that can be placed and preserved in the central part of the device 1 and of the placingdevice 21 throughout the phases of use of the invention. -
FIGS. 4 and 5 show anouter casing 2 able to implement the main body and to delimit an inner working space. The outer casing comprises a distal end formed by anose 14 with a tapered shape configured to enable insertion in the vessel through the wall thereof. - During use, the
nose 14 is first of all in the default closed position so as to constitute the tapered insertion profile. When thenose 14 is sufficiently inserted in the vessel, opening means are present to open thenose 14. - An example embodiment of these opening means is presented below. Thus, in the context of
FIGS. 4 and 5 , thenose 14 is equipped with a plurality ofslots nose 14 intoseveral segments segments nose 14 to be opened in a movement substantially corresponding to that of the petals of a flower. - The number of
slots - Advantageously, the
segments nose 14 have a shape memory in order to regain the closed idle position thereof when the opening means are no longer active. It is thus possible to open and close thenose 14 on several occasions, according to the requirements of the practitioner. - It is possible to provide other means for closing the
nose 14, in the form of an active closure system for example by slipping a wire into thevarious segments nose 14 and a peripheral handle: the tension of the wire closes thenose 14 and release may also serve for opening thenose 14. - At the opposite end of the
outer casing 2, ahandle 6 is present for gripping by the operator. It should be noted that theouter casing 2 delimits an inner space enabling, for example, insertion of avascular occlusion device 10 presented inFIG. 10 and comprising twoexpandable members intermediate part 26 deformable under torsion. - Docket: 2160-15 CON
- The device 1 and the placing
device 21 also comprise aninner sheath 3 able to be mounted slidably in the internal space of theouter casing 2. Just like theouter casing 2, theinner sheath 3 may consist of a substantially cylindrical portion with a circular cross-section. The distal end of the inner sheath is left free while the other end comprises ahandle 7 for gripping by the practitioner. - The invention also comprises a pusher 4 visible in
FIG. 10 in a preferred embodiment in which it has acentral channel 27 producing a residual passage in the core of the device as well as ahandle 12 receiving, in the case depicted, anend valve 22 and acoupling 23 for ancillary connections. The pusher 4 is mounted slidably in the internal space of theinner sheath 3. - Through this assembly, the configuration illustrated in
FIGS. 1 and 2 is arrived at. Thehandles spacers 8, 9 formed removably so as to be able to be successively removed during the surgery. - The
guide cable 11 is here positioned in the residualcentral channel 27 of the pusher 4 and its proximal end is associated with a sleeve also allowing manipulation. - In the example illustrated, the opening of the
nose 14 takes place as follows. From a closed position, appearing for example inFIG. 11 , the practitioner removes the first spacer 8 so as to enable theouter casing 2 to be withdrawn relative to theinner sheath 3 until thehandles inner sheath 3 exerts an abutment on the internal wall of theouter casing 2 via anexpandable member 24 of theimplant 10. This abutment causes the deployment of thesegments nose 14 as is clear fromFIG. 14 . - According to one possibility, isolated joins 17 are present over the length of the
slots various segments nose 14 and to make it possible to detach thevarious segments inner sheath 3 when theouter casing 2 is withdrawn. - Spot welds may serve as joins 17.
- An example embodiment of a device for placing implants is described more precisely below, in the non-limitative case of the placing of vascular occlusion implants as shown in
FIG. 6 . - In this context, the
implant 10 is positioned in the internal space of theouter casing 2 before the start of the operation. More precisely, the distalexpandable member 24 is held by the internal wall of theouter casing 2. At the rear, anotherexpandable member 25 is held in position against the internal wall of theinner sheath 3. Advantageously, the rear end of theexpandable member 24 is put in abutment on the front end of theinner sheath 3. In parallel, the rear end of theexpandable member 25 is put in abutment against the distal end of the pusher 4. This configuration is shown clearly inFIG. 11 . - First, the practitioner inserts the
nose 14 through the vascular wall until it arrives at the required implantation. At this stage, the spacer 8 is removed, which enables the practitioner to withdraw theouter casing 2 relative to theinner sheath 3, by means of thehandle 6. This movement is illustrated inFIG. 12 . It gives rise to an abutment of theexpandable member 24 andinner sheath 3 on the internal wall of theouter casing 2 able to deploy thenose 14 by separation of thevarious segments FIG. 14 , where the expansion of theexpandable member 24 once released can be noted. - At this level, the other
expandable member 25 is also held inside theinner sheath 3. - For an application to vascular occlusion, it is then possible to effect a rotation of the
inner sheath 3 so as to modify the relative angular positions of theexpandable members handle 7 to modify the angular position thereof. Naturally, in this application, it is necessary for theinner sheath 3 to have a possibility of rotational movement on the longitudinal axis of the device. Furthermore, it is advantageous to provide means for adjusting the angular position of theinner sheath 3, for example in the form of areference 19 situated on thehandle 7 opposite a plurality ofgraduations 20 formed on the external surface of the pusher 4 at a point visible to the user. He can thus adjust the torsion imposed on theintermediate part 26 in order to adjust the degree of occlusion, which may also produce an adjustment of the length of theimplant 10 by effecting a greater or lesser number of turns. This possibility is illustrated by the double arrow inFIG. 16 . - By removal of the
spacer 9, the assembly consisting of theouter casing 2 and theinner sheath 3 is withdrawn by a rearward translation movement exerted at thehandle 6 in order to move it closer to thehandle 12 as far as abutment. - At this stage, the abutment exerted by the pusher 4 on the rear end of the
expandable member 25 produces the release of saidexpandable member 25 from the internal wall of theinner sheath 3. This release causes the expansion of themember 25 for placing thereof on the vascular wall. In this way the situation illustrated in detail inFIG. 18 is arrived at, where thenose 14 is retracted with respect to theinner sheath 3, the latter itself being retracted with respect to the pusher 4. Naturally, here, the relative retraction positions are accentuated for good comprehension. - The
guide cable 11 can be withdrawn or could have been withdrawn previously. It will be noted that thenose 14 comprises a residualcentral passage 14 visible in front view inFIG. 4 to enable thecable 11 to be inserted and removed. - The
spacers 8 and 9 here consist of the elements having an annular cross-section in a lunar crescent of more than 180°. The remaining opening makes it possible to act on the elasticity of the material of the spacer in order to achieve removal thereof. An example of a shape of thespacers 8, 9 is present in the case of the spacer 8 inFIGS. 7 and 8 . Naturally, another configuration is possible with other means enabling the spacer to be removed. - The main constituents of the invention are, by way of example, made from polyurethane or polyethylene.
- While the present invention has been shown and described with reference to certain embodiments thereof, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
