ABSTRACT:
An implantable lead for a cardiac stimulator has an electrode at its distal end, and resilient, non-penetrating, tissue-contacting elements integral with the lead in the vicinity of the electrode. The resilient elements are movable from a first unextended position for ease of insertion or withdrawal of the lead through the vein of a patient to a second extended position for contacting tissue to retain the electrode in a selected location in the heart of the patient. A device operable along the lead serves to selectively move the resilient elements from the unextended to the extended position or vice versa.
