Claim:
1. An endovascular prosthesis comprising: an inner polymer structure that extends from a distal end to a proximal end along a longitudinal axis, the inner polymer structure having an inner surface facing the longitudinal axis with a first plurality of pores with each pore extending from the inner surface to an outer surface of the polymer structure; and an outer thin-film shape-memory structure having an inner thin-film surface coupled to the outer surface of the inner polymer structure from the distal end to the proximal end with a retrieval member at the proximal end to allow for the prosthesis to be retrieved after placement in a body vessel, the outer thin-film shape-memory structure configured with a second plurality of pores with each pore extending from the inner thin-film surface to an outer thin-film surface so that fluid communication is provided from inside of the inner polymer structure to the body vessel.
