An implantable medical device, perhaps a pacemaker lead, has a medical unit and a casing at least partially enclosing the medical unit. The casing is formed of a base polymer having surface modifying pendant groups formed of an acrylamide polymer or an acrylamide copolymer, perhaps polyisopropyl acrylamide. The base polymer may be a polyurethane, polyimide, fluoropolymer or polyolefin, for example.
L'invention concerne un appareil médical implantable, par exemple une dérivation de stimulateur cardiaque, qui comprend un dispositif médical et une enveloppe renfermant au moins partiellement le dispositif médical. L'enveloppe est faite d'un polymère de base comportant des groupes latéraux de modification de surface constitués d'un polymère d'acrylamide ou d'un copolymère d'acrylamide, éventuellement d'un polyisopropyl acrylamide. Le polymère de base peut être, par exemple, un polyuréthane, un polyimide, un polymère fluoré ou un polyoléfine.
