FLEXIBLE CONDUCTIVE POLYMER BASED CONFORMABLE DEVICE AND METHOD TO CREATE LINEAR ENDOCARDIAL LESIONS

摘要

An ablation device for creating linear lesions comprises a flexible support structure defining at least a partial curve; and an electrode disposed on the flexible support structure. The electrode comprises a pressure sensitive conductive composite that is configured for electrical communication with an electrical conductor and a flexible conductive outer covering that covers at least a portion of the pressure sensitive conductive composite. Electrical resistance of the pressure sensitive conductive composite varies inversely in proportion to pressure that is applied to the pressure sensitive conductive composite. Methods of creating linear lesions are also provided.
