First Claim
Patent Images
1. An endoluminal prosthesis, comprising:
- a tubular wire support having a proximal end, a distal end and a central lumen extending therethrough;
the wire support comprising at least a first and a second axially adjacent tubular segment, joined by a connector extending therebetween;
wherein the first and second segments and the connector are formed from a single length of wire.

14. A method of making an endoluminal prosthesis, comprising the steps of:
-
providing a length of wire;
forming the wire into two or more zig-zag sections, each zig-zag section separated by a crosslink;
rolling the formed wire about an axis to produce a series of tubular elements positioned along the axis such that each tubular element is connected to the adjacent tubular element by a link. - View Dependent Claims (15, 16, 17)

18. A multizone endoluminal prosthesis, comprising:
-
a tubular wire support having a proximal end, a distal end, and a central lumen extending therethrough;
the wire support comprising at least a first and a second axially adjacent tubular segments, joined by a connector extending therebetween;
wherein the first tubular segment has a different radial strength than the second tubular segment. - View Dependent Claims (19, 20)

- 21. An endoluminal prosthesis, comprising an elongate flexible wire, formed into a plurality of axially adjacent tubular segments spaced along an axis, each tubular segment comprising a zig zag section of the wire, having a plurality of proximal bends and distal bends, with the wire continuing between each adjacent tubular segment, wherein the prosthesis is radially compressible into a first, reduced cross sectional configuration for implantation into a body lumen, and self expandable to a second, enlarged cross sectional configuration at a treatment site in a body lumen.

34. A method of implanting an endoluminal vascular prosthesis, comprising the steps of:
-
providing a self expandable endoluminal vascular prosthesis, having a proximal end, a distal end and a central lumen extending therethrough, said prosthesis expandable from a first, reduced diameter to a second, enlarged diameter;
mounting the prosthesis on a catheter, such that when the prosthesis is in the reduced diameter configuration on the catheter, the catheter diameter through the prosthesis is no more than about 16 French;
introducing the catheter into a body lumen, and positioning the prosthesis at a treatment site in the body lumen;
releasing the prosthesis at the treatment site, such that the prosthesis expands from the first diameter to the second diameter;
wherein the second diameter is at least about 20 mm.
