Abstract:
1. A self-expanding support for a body conduit comprising: a substantially tubular framework delimiting a multiplicity of fenestrations; a filter device attached to said tubular framework, said filter device comprising: wherein said bioabsorbable filter elements converge at a center region to form a generally conical structure with openings between said filter elements for fluid therethrough; wherein portions of said filter elements at said center region of said conical structure are bioabsorbed prior to portions of said filter elements located at a periphery of said filter elements, wherein said framework is continuous, non-filamentous, non-braided, and non-interlaced; wherein said framework is made of a non-blended hydrolysable co-polymeric material comprising an amorphous component with a glass transition temperature that is below ambient body temperature and a crystallizable component that possesses a crystalline melting point in excess of ambient body temperature; and wherein said framework expands radially from a compressed first diameter to an uncompressed second diameter below normal human body temperature without requisite for an externally applied force and without requisite for a thermal transition of said polymeric material.
