Abstract:

A left ventricular stimulation lead construction and a technique for lead placement that provides for improved anchoring and positioning of the electrode located on the distal end of the lead, while also including a method for readjusting the positioning of the lead as necessary. The lead includes a small diameter guide wire wherein the distal end of the guide wire serves as an anchor for the pacing lead. The lead structure includes a central hollow lumen to allow passage of the guide wire and a locking mechanism positioned on the proximal end of the pacing lead to fix the ends of the guide wire and pacing lead relative to one another. The method provides for advancing the guide wire until it is anchored, positioning the pacing lead along the guide wire into the desired position relative to the cardiac tissue, releasably fixing the lead relative to the guide wire, wherein the guide wire is permanently retained to serve as an anchor.
