Abstract
An implantable prosthesis, including a generally tubular substrate and a continuous shape memory member disposed over the outer surface of the substrate. The shape memory member may include a series of zig-zag struts alternating between a first strut with a first length and a second strut with a second length different from the first length. A graft member may be positioned over the substrate and shape memory member.
Claims20
A stent-graft, comprising:
- a longitudinally compressed, generally tubular substrate having a first end and a second end along a longitudinal axis;
- a continuous member positioned over an outer surface of the substrate from the first end to the second end, the continuous member including a series of zigzag struts alternating between a first strut with a first length and a second strut with a second length different from the first length, adjacent first and second struts connected at one end thereof to form a first angle therebetween, bisection of the first angle by a line parallel to a longitudinal axis of the substrate forming a second angle between the line and the first strut, and a third angle equivalent to the second angle between the line and the second strut;
- and
- a graft member attached to at least one of the substrate and continuous member in a tensioned state, the graft member including polymer fibers woven or knitted into a generally tubular shape.

A stent-graft, comprising:
- a tubular substrate having a first end and a second end along a longitudinal axis, the tubular substrate having a first relaxed length and a second compressed length less than the first relaxed length;
- a continuous member positioned over an outer surface of the substrate from the first end to the second end at the second compressed length;
- and
- a graft member attached to at least one of the substrate and continuous member in a tensioned state, the graft member including polymer fibers woven or knitted into a generally tubular shape.
