Patent number: 8142491Abstract: In accordance with the present invention, there is provided a stent for insertion into a vessel of a patient and a method for manufacturing the same. The stent has front and back open ends and a longitudinal axis extending therebetween. The stent has a plurality of adjacent hoops that are held in alignment with the longitudinal axis between the front and back open ends by a thin film tube. The hoops are attached to either the inner or outer surface of the thin film tube. The stent is compressed into a first smaller diameter for insertion into the vessel with a delivery tube and a second larger diameter for deployment into the vessel. The inventive stent can be retracted into the delivery tube if it is improperly deployed.Type: GrantFiled: October 29, 2009Date of Patent: March 27, 2012Assignees: Cordis Corporation, Advanced Bio Prosthetic Surfaces, Ltd.Inventors: Carolyn Rice, Craig Bonsignore

Patent number: 8128690Abstract: The present invention consists of an implantable structural element for in vivo 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. Alternatively, the implantable structural element may simply be an implantable article that serves the single function of acting as a time-release carrier for the bioactive agent.Type: GrantFiled: July 15, 2010Date of Patent: March 6, 2012Assignee: Advanced Bio Prosthetic Surfaces, Ltd.Inventor: Christopher T. Boyle
