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.揭示一種合成物式血管內裝置之各種實施例(及其變化例),該合成物式血管內裝置包括一內部聚合物結構及一外部薄膜記形結構。該內部聚合物結構沿縱軸從遠端延伸至近端。該外部薄膜記形結構具有一內部薄膜表面,該內部薄膜表面經從該遠端至該近端耦合至該內部聚合物結構之該外部表面,在該近端處具有一取回構件,以允許在將該假體置入一身體脈管後將之取回。該內部聚合物結構可混有一合適的生物活性劑或該劑可經裝載入孔中。本裝置因係為可取回的而可為永久性或暫時性。100‧‧‧血管內假體/裝置/假體100a‧‧‧遠端100b‧‧‧近端102a‧‧‧內部表面102b‧‧‧外部表面103‧‧‧內部104‧‧‧洞106‧‧‧薄膜結構108‧‧‧取回構件/鉤110‧‧‧洞/外部薄膜結構112‧‧‧脈管/血管116‧‧‧導引線管腔/導線120‧‧‧膨脹管腔/膨脹開口
