Endoluminal vascular prosthesis
First Claim
Patent Images
1. A method of making an endoluminal prosthesis, comprising the steps of:
- providing a length of wire;
forming the wire into at least two zig-zag sections having proximal and distal apexes;
rolling the formed wire about an axis to produce at least two tubular elements positioned along the axis such that at least one proximal apex on one element axially overlaps with a distal apex on a second element;
folding one of the proximal or distal apex through the overlapping proximal or distal apex to produce a folded link; and
closing the folded link such that the folded apex forms a functionally closed aperture which substantially entraps the overlapping apex.

5. A movable link for securing two portions of the wall of a tubular endovascular prosthesis, comprising:
-
a first wire portion having two side-by-side legs and an apex thereon; and
a second wire portion adjacent the first wire portion;
wherein the first wire portion is wrapped around the second wire portion to form a functionally closed aperture, wherein the second wire portion is substantially entrapped within the aperture.
