Abstract
Various embodiments for a composite endovascular device (and variations thereof) that include an inner polymer structure and an outer thin-film shape memory structure. The inner polymer structure extends from a distal end to a proximal end along a longitudinal axis. The outer thin-film shape-memory structure has 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 inner polymeric structure can be blended with a suitable bio-active agent or the agent can be loaded into the pores. The device can be permanent or temporary by virtue of being retrievable.
