Abstract

ENDOVASCULAR PROSTHESIS WITH SUTURE HOLDER. Said prosthesis comprises prosthetic body (b) on the internal surfaces (2) of which a number of connectors (4) are distributed and attached that, on the one hand, connect respective semi-flexible cables (b) ending in external rotary control ends (9′), while, on the other hand, they are passed through by respective spiral sutures (6) controlled by said semi-flexible cables (b). Once prosthetic body (b) is expanded, its external surfaces (3) are in contact with vascular walls (1). With this arrangement, the rotary actuation of semi-flexible cables (c) permits penetration ends (6′) of spirals (6) to pass through vascular walls (5). This penetration continues until anchoring ends (7) of above-cited spirals (6) stop against bases (4′) of respective connectors (4). In this manner, a firm union is created between vascular channel (a) and prosthetic body (b).

Claims

1. ) ENDOVASCULAR PROSTHESIS WITH SUTURE HOLDER:

of the type that, since it can be introduced endoluminally into a vascular channel for application, comprises a prosthetic body with cylindrical walls and open bases that can be radially expanded up to the limit at which its external surfaces contact the damaged vascular walls of the above-cited vascular channel, with the internal surfaces of said body forming a prosthetic circulatory passage;

characterized in that it comprises;

a) a number of connectors that, distributed such that they encircle the cylindrical walls of the prosthetic body, are attached to the internal surfaces of said cylindrical walls;

b) in each connector, the rotary end disconnectable from a respective semi-flexible cable as an applicator of sutures, which cable extends beyond said prosthetic passage, terminating in an external rotary control end; and

c) passing through each connector and the adjacent cylindrical wall of said prosthetic body, a respective spiral suture, the anchoring end of which is inserted in said rotary end of its respective semi-flexible cable.

2. ) ENDOVASCULAR PROSTHESIS WITH SUTURE HOLDER, pursuant to claim 1:

characterized in that the connectors consist of parts in the shape of small disks, the base of which constitutes a penetration stop for the anchoring end of the respective spiral suture.

3. ) ENDOVASCULAR PROSTHESIS WITH SUTURE HOLDER, pursuant to claim 1:

characterized in that the external control ends of the semi-flexible cables form connecting ends with a rotary device.

4. ) ENDOVASCULAR PROSTHESIS WITH SUTURE HOLDER, pursuant to claim 1:

characterized in that the spiral sutures pass through the connectors and the walls of the prosthetic body between two alternative end positions;

one for prosthetic positioning, in which its anchoring ends are inserted in the ends of its respective semi-flexible cables; and

another prosthetic-placement position in which the sharp ends of said spirals protrude through the prosthetic walls and pass through vascular walls for the application.

5. ) ENDOVASCULAR PROSTHESIS WITH SUTURE HOLDER, pursuant to claim 1:

characterized in that the walls of the prosthetic body are composed of a thermo-expandable material.

6. ) ENDOVASCULAR PROSTHESIS WITH SUTURE HOLDER, pursuant to claim 1:

characterized in that the connectors encircle the interior of the cylindrical walls, lining them in circular fashion.
