Abstract: The invention is a stent-graft device having a support component with multiple turns of an undulating member where the undulations have a number of apexes. The graft component of the device is substantially coaxial with the support component and is attached to the support component so as to allow a number of the support component's apexes to move relative to the graft.

Abstract: This is a medical device and a method of using it. The device is a foldable stent-graft which may be percutaneously delivered with (or on) an endovascular catheter or via surgical techniques or using other suitable techniques and then expanded. The stent-graft uses a kink-resistant stent structure and an interior graft which is attached to the stent in such a way that the graft does not kink and yet the stent is able to conform to curves in the blood vessel lumen.

Abstract: This is a medical device and a method of using it. The device is a foldable stent-graft which may be percutaneously delivered with (or on) an endovascular catheter, via surgical techniques or using other suitable techniques and then expanded. The stent-graft uses a kink-resistant stent structure and an interior graft which is attached to the stent in such a way that the graft does not kink and yet the stent is able to conform to curves in the blood vessel lumen. The expandable stent structure preferably has a helically deployed torsional member with an undulating shape which is wound to form the generally cylindrical shape deployed as the stent. The helical winding desirably is aligned to allow undulations in adjacent turns of the helix to be in phase. The adjacent undulating shapes are held in that phased relationship using a flexible linkage, typically made of a polymeric material. The graft component cooperating with the stent is tubular and mounted on the interior of the stent.

Abstract: The present invention relates to a stent-graft where the stent is formed from a self-expanding material and is coaxially and slidably coupled to the graft component which contains collagen. At least one flexible linkage is provided for coupling the stent and graft together in the slidable manner.
