Definitions
- the present invention relates to an angioplasty device for arterial bifurcation.
- the invention relates to a device specially adapted for the non-surgical treatment of arterial lesions which affect bifurcations of arteries, this device allowing the treatment of the lesion by inflation of a balloon and on the other hand, the placement of a prosthesis element at the bifurcation.
- Atheromatous lesions of large arterial vessels are the leading cause of morbidity and mortality in developed countries. Since 1978, following Gruntzig's work, the majority of these lesions are accessible by percutaneous balloon angioplasty.
- This technique consists in placing percutaneously an inflatable balloon at the height of the arterial lesion and in inflating this balloon to remedy the stenosaut lesions of the arteries.
- angioplasty is used in current practice in the treatment of stenosaut lesions of the coronary, renal arteries and large vessels of the lower limbs.
- This technique has the considerable advantage of avoiding surgical intervention at the level of the artery having undergone the lesion.
- a surgical intervention would not be possible, because of the duration of the intervention that should be done and the consequences of this on the patient.
- An object of the present invention is therefore to provide such material which allows in particular in the case of coronary treatment intervention by angioplasty involving the entire area of arterial bifurcation.
- the angioplasty device comprises: an inflatable balloon in the form of Y having a trunk and two arms connected to said trunk limited by a single deformable waterproof wall, said trunk having a connection end and each arm having a terminal end, said balloon having two internal conduits for guide wires, each conduit extending from the connection end to one of the terminal ends and a catheter having a first internal end integral with the connection end of said balloon and a second external end, said catheter having an inflation channel extending over the entire length of the catheter, a first end of said inflation channel opening into said balloon, the second end of said inflation channel opening at the outer end of said catheter, and two guide channels ge extending at least over the terminal part of the catheter, each channel having a first end for introducing a guided wire and a second end connected to a conduit of said balloon, each guide channel being capable of receiving a guide wire .
- the balloon being in one piece, it can effectively conform to the shape of the arterial bifurcation and therefore produce an effective angioplasty effect at any point of the arterial wall.
- the angioplasty device comprising only one catheter into which the two guide wires are introduced, the introduction of the single catheter and of the guide wires will of course be much simpler than in the case where two catheters each associated with one of the balloons had to be used.
- Figure 1 is a simplified view of the entire angioplasty device;
- Figure 2a shows the section of the catheter in its terminal area;
- FIG. 2b shows this same section according to an alternative embodiment
- Figures 2c, 2d and 2e show the section of the catheter along the plane CC of Figure 1 for different embodiments of the invention
- Figure 3 shows in partial section the connecting end of the catheter
- Figure 4 shows a preferred embodiment of the angioplasty balloon
- Figure 5 is a detail view of Figure 4 showing the connection between the catheter and the angioplasty balloon
- Figure 6 illustrates the placement of an arterial prosthesis in Y on the balloon.
- FIG. 1 we will describe the entire angioplasty device.
- This essentially consists of a catheter 10, the external end 12 of which is provided with a connection device 14.
- the connection device 14 is preferably connected to a source of pressurized fluid which may be a pressure gauge equipped with a non-return valve 18.
- the internal end 20 of the catheter 10 is connected to an angioplasty balloon 22 which comprises on the one hand a trunk 24 and on the other hand two branches 26 and 28, the balloon thus having the shape general of a Y.
- the trunk 24 and the branches 26 and 28 are limited by a same deformable wall 30 preformed to define the Y shape.
- two ducts 32 and 32 are provided respectively. 34, which extend from the connection end 36 of the trunk 24 to each of the ends 38 and 40 arms 26 and 28.
- the conduits 32 and 34 pass through the wall 30 of the balloon in a sealed manner.
- the catheter 10 has an axial inflation channel 42 which extends over the entire length of the catheter.
- a first end 42a of the channel 42 opens into the connection device 14, while its other end 42b, as will be explained later, opens inside the balloon 22.
- the catheter 10 also comprises two guide channels 44 and 46 each intended to receive a guide wire 48 and 50.
- the guide channels extend over at least the end portion 10a of the catheter which has a length LI.
- the distal end of each guide channel is connected to one of the guide conduits 32, 34 of the balloon, these conduits constituting extensions of the guide channels.
- the catheter 10 has a total length of the order of 175 cm and its terminal part has a length LI of the order of 30 cm.
- the two guide channels extend over the entire length of the catheter. This is illustrated in Figure 2c.
- each channel opens out through a lateral opening 52 near the connection member 14.
- This solution requires the use of guide wires the width of which is twice that of the catheter.
- Another solution consists in providing a first channel 44 which extends over the entire length of the catheter, the other channel 46 extends only over the length of the end portion 10a of the catheter. This is shown in Figure 2d.
- the channel 46 opens into the side wall of the catheter at the end of the terminal zone 10a.
- a third solution is to provide the catheter with a first channel
- the 44 has a longitudinal slot 60 which opens into the external wall of the catheter.
- the slot 60 extends over the entire length of the catheter with the exception of the terminal portion 10a.
- the latter solution allows rapid removal of the corresponding guide wire.
- at at least one of the channels 44, 46 has, in its terminal part, orifices 64 which open into the channel and into the external face of the catheter. These orifices make it possible to maintain a certain blood circulation even when the balloon 22 placed in the artery is inflated, while the guide wire is withdrawn upstream to a radiopaque mark.
- the connecting piece 14 allows to connect the end 42a of the inflation channel to a source of pressurized fluid 62, this fluid serving to inflate the balloon 22.
- a source of pressurized fluid 62 This is for example d '' a pump or a pressure gauge.
- the pump 62 is mounted on the connecting piece 14 by means of a non-return valve 64 so that, when the pump is disconnected, the end 42a of the inflation channel is closed.
- the ends 38 and 40 of the branches of the balloon have a certain rigidity in order to preform the balloon with its Y shape even when it is not inflated. These ends are tightly connected to the external face of the conduits 32 and 34. Likewise, the end 36 of the trunk of the balloon also has greater rigidity and is fixed by any suitable means, for example, by welding, to the end of the catheter.
- FIG. 5 the continuity between the guide channel 44 and the conduit 32 as well as the continuity between the channel 46 and the conduit 34 is more clearly represented.
- the end 42b of the channel inflation opens into an orifice 70 arranged in the end 36 of the balloon.
- Figure 4 there is shown the balloon placed in the arterial bifurcation A and inflated.
- the diameter D of the trunk of the balloon is slightly greater than the diameter D 'of each branch of the balloon but less than the sum of the two diameters of the branches.
- the balloon once inflated can conform not only to the dimensions of the arteries forming the bifurcation but also to that of the artery upstream of the bifurcation.
- an introducer mesil is put in place comprising a valve, either the femoral artery, or on the radial artery or on the right or left numerical artery, depending on the position of the arterial bifurcation which is wants to deal with.
- a first guide wire is introduced, for example, the wire 50 so that it enters one of the two arteries constituting the bifurcation.
- the catheter 10 is placed in such a way that the ends 38 and 40 of the balloon which, of course, is not inflated, is slightly upstream of the bifurcation proper.
- the second guide wire 52 is put in place so that it enters the other artery constituting the bifurcation.
- this second guide wire can be obtained in two different ways. Or the second guide wire is introduced using the second guide channel, in the case where the catheter actually has two guide channels over its entire length. Either the end of the second guide wire can be put in place in the guide channel and in the corresponding guide duct before putting the balloon and the catheter in my waiting position indicated above. In this case, it then suffices to act on the terminal end of the second guide wire to make the free end of the latter penetrate into the desired artery of the bifurcation. When the two guide wires have been placed in the arteries of the bifurcation, it is then sufficient to cause the displacement of the balloon using the catheter.
- each guide wire enters one of the arteries of the bifurcation
- each branch or arm of the balloon easily penetrates into each of the arteries of the bifurcation.
- the correct positioning of the balloon can be checked using a radio-opaque marker provided on the catheter. We can then proceed to the desired inflation of the balloon to cause the extension of the arterial walls in the bifurcation zone.
- the balloon 22 can be used to place a Y-shaped arterial prosthesis element.
- the prosthesis 70 is made of a suitable material capable of retaining its extension after removal of balloon 22 for positioning.
- This prosthesis 70 of course has a Y shape and is engaged on the balloon 22 which is not inflated, as shown in FIG. 6.
- the balloon 22 for positioning is deflated and then removed from the artery thereby releasing the prosthesis element which remains in place at the bifurcation.
