ENDOCARDIAL ELECTRODE ASSEMBLY HAVING CONDUCTIVE FIXATION FEATURES

摘要

A lead (100) having a distal end electrode assembly (130) adapted for implantation on or about the heart or within a vein and for connection to a system for monitoring or stimulating cardiac activity. The electrode assembly includes conductive fixation features, such as conductive tines (320) or flexible members, in combination with non-conductive fixation features (340). The conductive fixation features also include tines coated with a conductive material. The fixation features further include conductive tines which are retractable. A defibrillation coil is optionally disposed at the distal end of the lead in combination with the conductive tines.
