Abstract
Undesired agents, which can reduce biocompatibility, can be selectively and substantially removed from implantable medical devices using methods of the present invention. Pressure and temperature of a supercritical fluid are adjusted to selectively remove one or more undesired agents from an implantable medical device perfused with the supercritical fluid. Treated implantable medical devices comprising at least about 75 wt % less of at least one undesired agent than the same device before undergoing a treatment are also disclosed.
