An endovascular support device for treatment of chronic restenosis or other vascular narrowing is disclosed together with a method of manufacture and a method for delivering a plurality of such devices to an affected area of a vessel. In a preferred embodiment, the endovascular support device comprises a unitary wire-like structure configured to form a plurality of upper and lower peaks which may be compressed for delivery to an affected area of a coronary or peripheral vessel in a human, and then expanded to maintain a passageway through the vessel.

Endovascular support device and method

An endoprosthesis is provided having an expandable, generally cylindrical body portion defining an inside surface and an outside surface. The inside surface is preferably regular and smooth to yield a low coefficient of friction, while the outside surface is modified to yield a relatively high coefficient of friction with a vessel surface, includes a macroscopic surface modification to engage the vessel surface, or includes an adhesive coating that bonds the stent to the vessel surface.

Method and apparatus to prevent stent migration

An endoprosthetic device comprises at least two short stent segments welded together to form a connected stent. Each stent segment defines a single wire having straight sections integrally formed between axial turns. The welds are placed between stent segments at one or more aligned adjacent axial turns. The welded connected stent is flexible enough to allow it to pass through sharp turns and to be implanted to conform to the contour of the lesion to be treated. In one aspect of the invention all adjacent axial turns are welded together. In another aspect of the invention, selected adjacent axial turns are welded together to create a generally balanced spiral pattern of welds surrounding the cylindrical connected stent.
