Definitions
- the present invention relates to an angioplasty device. More specifically, the invention relates to a device which allows the placement of instruments by angioplasty of large arterial vessels and in particular but not exclusively in the carotid arteries. 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, as is well known, consists in placing an inflatable balloon at the height of the arterial lesion and in inflating this balloon to remedy the stenosaut lesions of the arteries.
- An object of the present invention is therefore to provide such material which allows in particular in the case of carotid treatment intervention by angioplasty without risking causing cerebrovascular accidents.
- the angioplasty device comprises: a first catheter intended to be introduced into the artery to be treated, comprising a first internal end and a second external end, said catheter being provided with a first internal inflation channel extending over the entire length of the catheter and with a second guide channel extending over the entire length of said catheter and capable of allowing a guide wire to pass, a first inflatable obturation balloon fixed at the first end of the catheter and connected to the first internal end of the first inflation channel, and a connection integral with the second end of the first catheter and capable of temporarily connecting said first channel to a source inflation fluid of said first balloon, a second catheter having a first inner end and a second outer end, said second ca theter comprising at its first end an angioplasty instrument, said second catheter comprising a first guide channel capable of at least partially surrounding said first catheter to be guided by it and a second activation channel of said angioplasty instrument, said second catheter being placed in said artery being guided by said first catheter.
- the angioplasty device it is possible, after the initial placement of the balloon protection using the first catheter upstream of the intervention area, to set up using the first catheter as a guiding element, an angioplasty instrument suitable for carrying out the intervention itself.
- the first obturation balloon after inflation, prevents entrainment of detritus resulting from the intervention by angioplasty to the cerebral arteries.
- a portion of said first catheter close to its first end comprises from its first end said inflatable balloon, a zone for placing said angioplasty instrument and a perforated zone, over the entire length of said portion of said guide channel not opening into the side wall of said first catheter, said guide channel being provided, in its perforated area, with openings communicating said guide channel with the outside of the catheter, said guide channel extending beyond said balloon and being open at its first end, said guide channel being split over its entire length outside said catheter portion to leave said guide wire free.
- the guide channel is only provided over a reduced length of the second end of the second catheter.
- the effective guiding of the second catheter by the first therefore only concerns a reduced length of the latter.
- the second catheter with its angioplasty instrument can, if necessary, be quickly removed from the patient's body.
- FIG. 1 is a schematic view showing the placement on a patient of the entire angioplasty device
- FIG. 1 is an elevational view of the first catheter provided with its inflatable balloon
- FIG. 3 is a sectional view along line III-III of Figure 2;
- - Figure 4 is a sectional view along the line IV-IV of Figure 2;
- FIG. 5 is a sectional view along the line V-V of Figure 2;
- FIG. 6 is a partial view showing the establishment of the protective balloon in the carotid artery
- FIG. 7 is a partial view showing a preferred embodiment of the connector of the first catheter
- FIG. 8 shows the establishment of the protective balloon using the first catheter and the second angioplasty intervention balloon using the second catheter in the carotid
- FIG. 9 is a cross-sectional view of the second catheter associated with the angioplasty instrument.
- FIGS. 9a, 9b and 9c are views of the second catheter of FIG. 9 in cross section respectively along the planes A-A, B-B and C-C of FIG. 9.
- This device essentially consists of a first catheter 10 at the end of which is mounted an artery obturation balloon 12 and which comprises at its second end a connector 14 on which an inflation pump can be mounted 16.
- the angioplasty device also comprises a second catheter 18 whose internal end is provided with an angioplasty balloon 20 and whose second end 22 is provided with a connection to a pump 24 for injecting the inflation liquid of the angioplasty balloon 20.
- the angioplasty device can comprise a third catheter 26, one end of which is provided with a prosthesis support tool 28 and the other end of which is provided with an instrument 30 the prosthesis.
- a guide wire 32 which is previously placed in the artery network allowing access to the area 34 where we want to perform the intervention and in particular beyond the connection of the carotid 36 as shown in Figure 1.
- the means of positioning the angioplasty device which consist essentially of an introducer mesh 40 comprising a valve. This desilet is placed either on the femoral artery, or on the radial artery, or on the right or left humeral artery.
- the catheter 10 is in known manner in the form of an elongated element of length equal, preferably, to 175 cm of circular section and sufficiently flexible. More generally, this catheter has a length of between 100 and 250 cm.
- the catheter 10 has a first end 10a intended to be introduced into the body of the patient and an external end 10b on which the connector 14 is mounted. From its internal end 10a, the catheter has a first end zone A and a current zone B whose length is of the order of 145 cm.
- a first zone A1 can be distinguished on which the obturation balloon 12 is fixed, then a free zone A2 on which the angioplasty balloon or another angioplasty tool will be positioned, then a zone A3 called perforated.
- the catheter 10 has a first longitudinal inflation channel 44 and a longitudinal guide channel 46. Over its entire length, the inflation channel 44 is surrounded by the material constituting the catheter and the first end of the channel 44 is connected to the connector 14 while the second end 44a of the channel 44 is open beyond the zone A1 of the fixing of the obturation balloon 12.
- the guide channel 46 is preferably provided with perforations such as 48 extending over the entire area A3. On the zone corresponding to the current part of the catheter, the guide channel 46 is provided with a slot 50 opening into the external wall of the catheter 10.
- the guide wire which is disposed in the guide channel 46 can be pulled out conveniently of the latter in the portion B.
- the inflation channel 44 opens into the sealing balloon 12 to allow inflation.
- the guide channel 46 is interrupted by a notch 50 constituting a guide wire stop.
- the connector 14 is provided with a check valve 54.
- the valve 54 is preferably of the ball type.
- This connection has a threaded portion 56 on which the pump or the syringe used to introduce the physiological saline can be fixed to inflate the obturation balloon 12. Thanks to the presence of the valve 54, the inflation channel 44 is closed when removes the inflation pump, which keeps the sealing balloon under pressure. After the guide wire is placed in the artery network
- the first catheter 10 is put in place using the wire as a guide so that the obturation balloon is disposed beyond the zone of intervention.
- Figure 6 there is shown the catheter 10 with its closure balloon 12 in place.
- the balloon 12 is properly inflated to effectively seal the artery. Thanks to the presence of the valve 54, the balloon remains inflated even after the inflation pump has been withdrawn. It is also understood that, thanks to the presence of the perforations 48 opening into the guide channel 46, despite obstruction of the artery by the balloon 12, a blood circulation via the guide channel is maintained downstream of the artery.
- the total length of the catheter 10 is of the order of 175 cm and its diameter of the order of 1 mm and the area A has a length of the order of 30 cm.
- the area A2 for placing the angioplasty balloon has a length of the order of 20 cm.
- the balloon 12 is made of latex or similar material and has a length of the order of 1 cm. This inflated balloon can reach a diameter of 9 mm.
- the second catheter 18 used for the actual angioplasty operation.
- This catheter 18 is provided at its end with the angioplasty balloon 20.
- the catheter 18 has a first zone C1 close to its terminal end 18a on which the angioplasty balloon 20 is mounted, a second zone C2 and then a running part D.
- the catheter 18 Over its entire length, the catheter 18 has an inflation channel 60, the first end of which opens into the balloon 20 and the second end of which is connected to a connector 62 which can itself be connected to an inflation pump 64.
- the catheter 18 has a guide channel 68 in which the first catheter 10 can slide for the placement of the angioplasty balloon.
- the guide channel is interrupted after a length 1 and in the main part D the catheter 18 simply includes the inflation channel 60.
- the guide channel 68 in the portion where it exists a diameter which is slightly greater than the external diameter of the first catheter 10. It is thus possible to place the angioplasty balloon 20 in the area of the artery where the operation is to take place.
- the angioplasty balloon is placed relative to the first catheter in the free area A2 thereof.
- the angioplasty device may include a third catheter 30 which can be engaged on the first catheter 10 in place of the catheter 18.
- This catheter 30 is provided at its internal end with a tool for positioning an angioplasty prosthesis.
- This third catheter also includes a guide channel similar to that of the second catheter and a second channel for containing the remote control means of the tool for placing the prosthesis.
- the device described above applies in particular to stenosing lesions of the vessels of the neck and in particular of the carotid arteries.
- the embolism protection system of the downstream bed sees its application widened to the treatment of lesions of venous grafts aorto-coronary saphenous.
- the downstream bed being protected, it is possible to slide the catheter of the protective balloon a "hydrolyzer" allowing to suck in and bring back the trombus safely.
- peripheral monorail dilation balloon can also be used for leg arteries, renal arteries, coronary arenas and bypasses (large caliber).
