<p>A lead assembly (10) adapted for endocardial fixation to a human heart is provided. The lead assembly includes a lead body (12) that has a proximal end provided with a connector (16) for electrical connection to a cardiac stimulator (18). The cardiac stimulator may be a pacemaker, a cardioverter/defibrillator, or a sensing instrument. The distal end of the lead body is connected to a tubular electrode housing (22). The lead body (12) consists of a noncoiled conductor cable (24) surrounded by a coextensive insulating sleeve (26). In contrast to conventional leads, the lead body of the present invention does not require coiled conductor wires or an internal lumen. Manipulation of the lead body is via an external guide tube. Lead body diameters of 0.25 mm or smaller are possible.</p> |
