Abstract
An implantable medical device is provided which comprises a fixed tissue incorporating an amount of an albumin-binding dye effective to form a coating of endogenous albumin on said device when the device is in contact with a physiological fluid containing albumin. These albumin-binding dyes have been found to significantly reduce calcification when incorporated in tissue heart valves. A method of increasing the albumin-binding ability of an implantable medical device is also provided.
