Definitions
- the present invention relates to a rapid exchange dilation catheter, intended to be introduced into a body channel such as in particular a blood vessel.
- the invention is mainly applied in the field of trai ⁇ ment of coronary artery disease but may also be used in the field of treatment of disorders of other body canals, such as the eosophage or urethra.
- a dilation catheter is generally used to restore the normal cross-section of the passage of the canal to the level of the stenosis by compression using a balloon (or balloon).
- a guide usually in the form of a wire, is used to facilitate the progression of the catheter to the stenosis.
- the guidewire is generally longer than the catheter (of the order of 20 to 50 cm) to allow advancement of the catheter inside the body canal, by sliding along the wire.
- a conventional dilatation catheter generally comprises a flexible tubular element comprising a distal part and a proximal part and having at its distal part a radially deformable portion forming a balloon, and at its proximal part a connector.
- This tubular element comprises a first internal through conduit intended to allow the passage of the guide wire inside the catheter and a second internal conduit, not communicating with said first conduit, opening into the interior of the balloon and connected to a source of fluid supply to allow inflation and deflation of the balloon.
- the aforementioned first internal conduit can also be used for the injection, at the level of the stenosis, of various diagnostic or treatment products intended for example to make the restoration of the passage section of the body canal lasting.
- the total length of the wire at course of the exchange procedure should be about 300 cm.
- Another known technique consists, during the exchange procedure in adapting to the free end of the guide wire another wire forming an extension (for example with a length of approximately 125 cm).
- the catheter described in this prior document comprises a distal part comprising two juxtaposed non-communicating internal channels, one of which (intended for the passage of the guide wire) opens out to the outside of the catheter.
- the catheter is crossed by the guide wire only over a small portion of its length (20 to 25 cm), less than the length of the wire extending outside the body (35 to 55 cm ), it is possible to remove the catheter by sliding it along the guide wire and to replace it with another catheter, without using a specific exchange wire or an extension.
- this catheter does not have a distal access route for the injection of a diagnostic or treatment liquid at the level of the stenosis.
- the workability of the guidewire is poor, insofar as it extends largely outside the catheter.
- the main purpose of the present invention is to solve the technical problem consisting in the supply of a rapid exchange dilation catheter, of a new design, which can be easily produced on an industrial scale, including work is easy, and allowing on the one hand a possible exchange of the guide wire by maintaining the catheter in position and the distal injection of liquid through the internal conduit of passage of the guide wire, and on the other hand a possible exchange holding the guidewire in position.
- the solution in accordance with the present invention, to solve this technical problem consists of a rapid exchange dilation catheter, intended to be introduced into a body channel such as in particular a blood vessel, of the type comprising:
- - a flexible tubular body comprising a distal part and a proximal part; - a radially deformable portion forming a balloon, disposed at the distal part of said body;
- a first internal conduit extending longitudinally inside said body, said conduit opening at one end inside the balloon in a sealed manner, and being connected at the other end to a source of fluid supply to allow inflating and deflating the balloon;
- a second internal conduit passing longitudinally through said body and not communicating with said first conduit, adapted to allow the passage of a guide wire inside said body; characterized in that it further comprises a third internal conduit not communicating with said first internal conduit extending in the vicinity of the portion forming a balloon, opening at a first end outside of said body and communicating at its other end so sealed with said second internal conduit; said third internal conduit being shaped so that the distal part of said guide wire can remain engaged in said body, while freeing said second internal conduit and thus allowing the installation, at least temporarily, of another wire- guide in said body.
- a “classic” rapid exchange operation that is to say the possibility of changing the catheter without adding an extension or using a special wire, and while maintaining the guide wire in position, the catheter thus being extracted by sliding along the wire;
- the third internal duct of the dilation catheter according to the invention is provided, at its end opening into the second internal duct with a locating means preferably constituted by a radiopaque element such as a metal ring.
- This locating means makes it possible to safely position the first guide wire in the standby position in the third internal conduit.
- the third internal conduit has, at its end opening to the outside of the catheter, the shape of a ramp intended to guide the wire towards the outside of the catheter.
- the above-mentioned flexible tubular body comprises:
- the above-mentioned flexible tubular body comprises:
- the length of the distal part increased by that of the intermediate part is less than the length of the guide wire outside the body when the latter is in the position of use.
- the opening of the aforementioned third internal conduit comprises a closure element forming a non-return valve comprising a slot allowing the passage of a guide wire. This conformation ensures stabilization of the guide in the standby position in the third internal conduit.

- the third internal conduit has, at its end which opens out to the outside of the catheter, the shape of a ramp intended to guide the wire towards the outside of the catheter. It should be noted that on the proximal portion of the intermediate portion 1b, that is to say on the length portion over which the third conduit 8 extends, the internal conduits 5, 6 and 8 are juxtaposed (see FIG. 1B ).
- the length of the distal part including the balloon portion increased by that of the intermediate part 1b will generally be much smaller than that of the proximal part 1a.
- provision will be made, by construction, for a body 1 whose length of the distal part 1a increased by that of the intermediate part 1b is less than the length of the wire remaining outside the patient's body when the said wire is in position of use, that is to say for example when the balloon is located at the level of the stenosis to be treated.
- the length of the distal part is increased by that of the part intermediate lb will be approximately 20 to 25 cm being specified that the balloon portion will have a length of the order of l to 5 cm.

- a third internal conduit 8 also makes it possible to exchange the guide wire while keeping the balloon in position. Indeed, the conduit 8 allows withdrawal of the first guide wire 7 in a
- a locating means constituted for example by a radio-opaque element such as a radio-opaque metal ring 11, will be mounted at the end of the third internal conduit 8 communicating with the second internal conduit 6 (see FIGS. 5, 6 and 7).
- This locating means may be made of the same material as the radiopaque ring 12 described above.
- first guide wire 7 when the first guide wire 7 is in the waiting position in the third internal conduit 8, it thus frees the distal part of the second internal conduit 6, and then allows the introduction, at least temporarily, of another guide wire 10 in the body of the catheter.
- the second internal conduit 6 thus released can also be used for the injection of products intended for the treatment of stenosis, or for the introduction of specific instruments such as for example a guide with Doppler type sensor.
- FIG. 4 shows a rapid exchange dilation catheter according to a second embodiment of the invention.
- the internal conduits 5 and 6 which extend substantially longitudinally inside the flexible body 1 are juxtaposed substantially parallel to one another in the proximal parts 1a (see FIG. 4A) and intermediate lb (see FIG. 4B) and coaxial in the distal part on (see Figure 4C).
- the body 1 also comprises a fourth internal duct 13 extending at the level of the proximal part 1a substantially between the connector 3 and the proximal part adjacent to the opening 9 of the third internal duct 8.
