Implantable medical device having biologically active polymeric casing.
Issued: November 22, 2005
Inventor: Kenneth B. Stokes
Key statement: An implantable medical device has a medical unit, such as a pacemaker lead, and a casing at least partially enclosing the medical unit. The casing is formed of a base polymer such as polyurethane, a polyurethane copolymer, a fluoropolymer and a polyolefin or a silicone rubber. The casing has biologically active agents covalently bonded to the base polymer. Examples of suitable biologically active agents are microbial peptide agents, detergents, non-steroidal anti-inflammatory drugs, cations, amine-containing organosilicones, diphosphohated, fatty acids and fatty acid salts.
