摘要:
In the present invention, the applicants describe methods and compositions of treating damaged cardiovascular elements and cardiovascular conditions including hypotension, atherosclerotic lesions, vulnerable plaque, and acute myocardial infarct. The applicants demonstrate the ability of a biomembrane sealing agent to accumulate on the walls of damaged blood vessels and help improving mean arterial pressure following tissue injury. The applicants describe the use of formulations comprising at least one biomembrane sealing agent and one bioactive agent for prophylactic treatment such as they could be administered concurrently to an invasive therapeutic intervention or after the insult (i.e. post-injury or post-surgery). Alternatively, these methods and compositions could be used to reduce the severity of cardiovascular diseases after onset.

摘要:
Disclosed are hindered amine nitric oxide (NO) donating polymers for coating implantable medical devices. The polymers include sterically hindered secondary amines that do not react with monomer carbonyls or electrophilic alkenes, facilitating the synthesis of the NO donating polymers. The polymers are coated on implantable medical devices, providing anti-restenosis therapy by the release of NO at the implantation site.
摘要:
Disclosed herein are implantable medical devices having controlled release biodegradable polymer coatings thereon wherein the polymer is formed from ring opening of γ-butyrolactone and at least one additional monomer selected from the group consisting of trimethylene carbonate, lactide, polyethylene glycol, glycolide, the monomers formed from ring opening of ε-caprolactone, 4-tert-butyl caprolactone, and N-acetyl caprolactone, and combinations thereof, and at least one drug releasable from the biodegradable polymer. Also disclosed are implantable medical devices form of the biodegradable polymers and processes for forming the polymers.
