Implantable cardiac lead with multiple shape memory polymer structures |
摘要 |
A cardiac lead is provided that is capable of deforming in situ to accommodate difficult myocardial structures. The lead includes a connector for coupling to a cardiac stimulator and a flexible tubular sleeve coupled to the connector. The sleeve is composed of a thermally-sensitive shape-memory polymeric material and is deformable in situ into a permanent shape. An electrode is coupled to the sleeve and a conductor wire is coupled to the connector and to the first electrode.
