摘要:
The present invention is directed to medical devices including coatings. The coatings include a topcoat which includes a copolymer comprising a block of an elastin pentapeptide. The topcoat is over a layer of poly(vinyl alcohol) on a hydrophobic coating or over a porous coating comprising pores or depots that include a bioactive agent.
摘要:
The present invention provides an implantable medical device coating that has improved stability, a medical device coated with such coating, and a method of increasing the stability of an implantable medical device coating, wherein the coating comprises a stereocomplex f poly(D-lactic acid) and poly(L-lactice acid).
摘要:
The present invention relates to implantable medical devices coated with polymer having tunable hydrophobicity and their use in the treatment of vascular diseases.
摘要:
A polymeric coating for a medical device that comprises poly(lactic acid) and a block copolymer including blocks of poly(ethylene glycol) and poly(butylene terephthalate) is provided.
摘要:
Provided herein is a PEA polymer blend and coatings or implantable devices formed therefrom. The PEA polymer blend is formed of a PEA polymer and a material capable of hydrogen bonding with the PEA. 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.
摘要:
The present disclosure teaches methods of controlling the release rate of agents from a polymeric matrix that include designing and creating a predetermined initial morphology (IM) profile in a polymeric matrix. The teachings indicate, inter alia, that control over the release rate of agents can provide for an improved control over the administration of agents as well as have an effect upon the mechanical integrity and absorption rate of the polymeric matrix.
