    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: Described herein are polymers useful for forming or coating implantable medical devices and such medical devices. The polymers are biocompatible and hemocompatible and comprise PTFE surfaces modified by covalently linking a nitric oxide releasing polymer to the PTFE surface through a linking group. Further described are precursor polymers and processes for preparing such polymers and precursor polymers.
