  • Publication number: 20090238854
    Abstract: A biocompatible plasticizer useful for forming a coating composition with a biocompatible polymer is provided. The coating composition may also include a biobeneficial polymer and/or a bioactive agent. The coating composition can form a coating on an implantable device. The implantable device can be used to treat or prevent a disorder 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.

  • Patent number: 7520891
    Abstract: Provided herein is a poly(ester amide) (PEA) polymer blend and a polymeric coating containing the PEA polymer blend. The PEA polymer blend has a Tg above the Tg of poly(ester amide benzyl ester) (PEA-Bz) or the Tg of poly(ester amide TEMPO). The PEA polymer blend can form a coating on an implantable device, one example of which is a stent. The coating can optionally include a biobeneficial material and/or optionally with a bioactive agent. The implantable device can be used to treat or prevent a disorder such as one of 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, and combinations thereof.

  • Publication number: 20080195194
    Abstract: A metallic alloy whose primary constituent elements are a relatively higher volume fraction of titanium and a relatively lower volume fraction of an added element or elements generally selected from the transition elements (excluding mercury, cadmium, osmium and copper). Medical devices formed from the metallic alloy are visible under MRI imaging and are sufficiently radiopaque for viewing by x-ray fluoroscopy. The alloy may be embodied in a multitude of medical devices.
