Abstract: A medical device comprising a coating thereon comprising a biocompatible polymer and heparin is provided herein. Heparin is coupled with the biocompatible polymer via a spacer having a grouping that renders a binding site of the heparin molecule accessible by a binding protein. The medical device can be implanted in a human being for the treatment of a disease such as atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, or combinations thereof.

Abstract: The bending flexibility profile of a stent closely matches the flexibilities of the stent delivery system on either side of the stent. In one embodiment, a stent has a longitudinal axis and at least one link attaching each ring to an adjacent ring. The links closest to the stent end rings have the greatest bending flexibility and the links closest to the center of the stent have the least bending flexibility.
Abstract: A polymer of hydrophobic monomers and hydrophilic monomers is provided. It is also provided a polymer blend that contains the polymer and another biocompatible polymer. The polymer or polymer blend and optionally a biobeneficial material and/or a bioactive agent can form a coating on an implantable device such as a drug delivery stent. The implantable device can be used for treating or preventing a disorder such as atherosclerosis, thrombosis, restenosis, hemorrhage, vascular dissection or perforation, vascular aneurysm, vulnerable plaque, chronic total occlusion, patent foramen ovale, claudication, anastomotic proliferation for vein and artificial grafts, bile duct obstruction, ureter obstruction, tumor obstruction, or combinations thereof.
Abstract: Medical assemblies with a releasable connection and methods of constructing such medical assemblies are disclosed. The medical assemblies generally comprise a stent, a catheter assembly having catheter body a balloon, and a releasable connection between the stent and the catheter assembly that releases the stent from the catheter assembly in response to enlargement of the balloon or when the balloon has been enlarged to an expanded configuration.
