1. A method for making an endoluminal prosthesis, comprising:
- joining an elongate support wire member to a polymer cladding;
helically wrapping a length of the joined support wire member and polymer cladding such that adjacent windings of the polymer cladding have overlapping regions;
heating the joined support wire member and polymer cladding above the melt point of the polymer cladding, wherein the wire member and polymer cladding together form a generally tubular structure having a first diameter; and
manipulating the generally tubular structure to a second diameter smaller than the first diameter.

Abstract
A method for making an endoluminal prosthesis for implantation within a body lumen to maintain luminal patency, the prothesis including a support structure, such as a wire member, and a polymer component, such as a polymer cladding. The method may include joining a wire member to a polymer cladding, helically wrapping a length of the joined support wire member and polymer cladding such that adjacent windings of the polymer cladding have overlapping regions, and heating the joined support wire member and polymer cladding above the melt point of the polymer cladding.
