1. A polymer prosthesis, comprising:
- a single generally tubular porous polymer member; and
a plurality of relatively stiff stenting segments that are windings of a continuous helical member spaced apart along a longitudinal axis of the porous polymer member, the stenting segments formed of a polymer different from the polymer of the porous polymer member, each stenting segment disposed at least partially within interstices of the porous polymer member.

Abstract
A polymer prosthesis with lumen and an axial length and having in a pre-delivery condition a plurality of relatively stiff stenting segments spaced from each other along the length of the prosthesis, the spaces between the relatively stiff stenting segments of a first polymer being bridged by relatively flexible linking segments of a second polymer, different from the first, the relatively stiff stenting segments and the relatively flexible linking segments being alternately arranged along the length of the prosthesis.
