Abstract

A stent-graft for insertion into a body vessel of a patient includes a hollow substantially cylindrical radially expandable stent having a body, two open ends and a longitudinal axis therebetween. The body of the stent is made from a plurality of interconnected struts. The stent-graft further includes a graft member attached to the body of the stent, wherein the graft member has a plurality of substantially longitudinally directed pleats disposed thereon. The graft further includes a plurality of radially oriented pleat interruptions disposed thereon.

Claims

1. A stent graft for insertion into a body vessel of a patient, said stent graft comprising:

a. a single hollow substantially cylindrical radially expandable stent having a body, two open ends and a longitudinal axis therebetween, said body comprising a plurality of interconnected struts; and

b. a graft member attached to said body of said single stent, said graft member having a plurality of substantially longitudinally directed pleats disposed thereon and a plurality of radially oriented pleat interruptions disposed thereon, said graft member and said single stent being substantially the same length.

2. The stent graft of claim 1 wherein said graft member is attached to an exterior surface of said stent.

3. The stent graft of claim 1 wherein said graft member is attached to said stent by a staple.

4. The stent-graft of claim 1 wherein said graft member is selected from a group of materials consisting of Dacron, Teflon, woven polyester, and polyurethane.

5. A The stent graft of claim 1 wherein said stent is a self expanding stent.

6. The stent graft of claim 5 wherein said stent is made from a superelastic alloy of nickel titanium.

7. The stent graft of claim 1 wherein said pleat interruptions comprise radial pleats.
