摘要：
The present invention consists of an implantable structural element for in vivo controlled delivery of bioactive active agents to a situs in a body. The implantable structural element may be configured as an implantable prosthesis, such as an endoluminal stent, cardiac valve, osteal implant or the like, which serves a dual function of being prosthetic and a carrier for a bioactive agent. Control over elution of the bioactive agents occurs through a plurality of cantilever-like cover members which prevent drug elution until an endogenous or exogenous stimulus causes the cover members to open and permit drug elution.
