Abstract
A transvenous, endocardial heart pacemaker lead having a conical fixation device on its distal end for holding a distal tip electrode in proper pacing position within the heart. There are open spaces around the conical surface of the fixation device defined by spaced apart, circumferential rings interconnected with spaced apart ribs extending lengthwise along the conical device. Engagement of trabeculae of the heart within the open spaces and against the rings holds the lead in place. An electrical conductor contained within an insulating sheath or catheter connects the distal tip electrode with a source of power. The conical fixation device is made out of flexible, nonconducting material.
