Covered stent with biologically active material

摘要

A composite device provides for the delivery of bioactive agents associated therewith. The device includes a first polymeric liner and a second polymeric liner bonded to the first liner. The device further includes an intermediate structural member interposed between the liner, which is defined by solid segments and openings between the solid segments. The liners are joined through the openings to form at least one pocket about the solid segments. A bioactive agent is located within the pockets about the solid segments of the intermediate structural member.
