Breakaway structure for body implantable medical device |
摘要 |
A cardiac lead is provided that includes a connector for connecting to a cardiac stimulator and a flexible sleeve coupled to the connector. The sleeve has a first segment, a second segment and a jacket coupling the first segment and the second segment. The jacket is composed of a shape-memory polymeric material which deforms diametrically in situ to selectively disconnect the first segment from the second segment. An electrode is coupled to the sleeve and a conductor is disposed in the sleeve and coupled to the connector and the electrode for conveying electrical signals. The breakaway function of the jacket allows removal of all but a small portion of the lead without dissection of fibrous tissue.
