Abstract
Abstract The invention covers removable endo-arterial devices intended to repair detachments in the arterial walls. A device according to said invention includes a deformable cuff (3) made of a netting of interlocked wires and fixed to the distal end of a catheter (4) the other end of which is equipped with a funnel (4a). It also includes a stiff wire (7) extending over the entire length of the catheter and attached to the distal end of said deformable cuff (3). When this wire is pulled, the cuff is dilated and applies itself against the arterial wall. One application is the repair of flaps of arterial wall which were detached during the course of an intervention correcting a stenosis with an inflatable balloon.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
114 words
A removable endo-arterial device for repairing detachments of an arterial wall, comprising a deformable cuff (3) made of a netting of plaited and interlocked wires which is mounted at the end of a catheter (4, 16) and introduced into an artery (1) . and which also includes means (7, 16) activated from the external end of said catheter (4) to bring two ends of said deformable cuff (3) closer together or move them farther apart in order to give it a wider shape which applies said cuff against the arterial wall or an elongated shape which permits said cuff and the catheter to be introduced into the artery or withdraw them from the latter.
Claim 2
Dependent Claim
114 words
A removable endo-arterial device for repairing detachments of an arterial wall, comprising a deformable cuff (3) made of a netting of plaited and interlocked wires which is mounted at the end of a catheter (4, 16) and introduced into an artery (1) . and which also includes means (7, 16) activated from the external end of said catheter (4) to bring two ends of said deformable cuff (3) closer together or move them farther apart in order to give it a wider shape which applies said cuff against the arterial wall or an elongated shape which permits said cuff and the catheter to be introduced into the artery or withdraw them from the latter.
Claim 3
Dependent Claim
62 words
The device according to claim 1, wherein said means to bring the two ends of said deformable cuff closer together or space them farther apart comprise a wire (7) of the piano-wire type, which is fixed to a distal end of said cuff while freely running through a proximal end of said cuff and extending through the entire length of the catheter.
Claim 4
Independent Claim
28 words
The device according to either of claims 1 and 2, further including a piece of flexible guide rod (6) attached to the distal end of said deformable cuff.
Claim 5
Independent Claim
52 words
The device according to either of claims 1 and 2, further including a guide tube (12) defining an axial conduit in the distal end of said deformable cuff, said guide tube being adapted to receive a guide wire (11) inserted into the artery and which returns through mesh openings in the netting.
Claim 6
Dependent Claim
24 words
The device according to claim 1, further including an inflatable balloon (13) mounted inside said deformable cuff at the end of an inflation tube
Claim 7
Dependent Claim
12 words
(14) which runs inside a catheter (16) carrying said deformable cuff (3).
Claim 8
Dependent Claim
12 words
(14) which runs inside a catheter (16) carrying said deformable cuff (3).
Claim 9
Dependent Claim
37 words
The device according to claim 5, further including an axial guide tube (15) which passes through said balloon, is fixed to the distal end of the latter and extends over the entire length of said catheter (16).
Claim 10
Dependent Claim
34 words
The device according to claim 6, wherein the distal ends of said balloon and said deformable cuff are fixed while the proximal end of said deformable cuff slides freely on said inflation tube (14).
