Medical electrical lead
First Claim
1. A cardiac pacing lead, comprising:
- an elongated conductor having proximal and distal ends;
an electrical connector coupled to the proximal end of said conductor;
an electrode coupled to the distal end of said conductor;
an insulative lead body enclosing said conductor; and
wherein said lead is formed to exhibit a curved configuration along a portion thereof; and
wherein said curved configuration comprises first and second arcuate segments together providing a single-plane curvature of approximately 180 degrees, said first and second arcuate segments separated by a generally straight segment, said first segment having a greater length and greater arc of curvature than said second segment.

Abstract
A cardiac pacing lead for use in the coronary sinus and coronary veins. The lead is provided with a lead body configured to exhibit a curved configuration along a distal portion thereof, induced to maintain a portion of the curved configuration solely by a portion of a polyurethane lead body formed to display the curved configuration and wherein the lead conductor is freely mounted within the segment The curved configuration includes first and second arcuate segments together providing a single-plane curvature of approximately 180 degrees, separated by a generally straight segment, the first segment having a greater length and greater arc of curvature than the second segment. The lead body encloses a first conductive coil coupled to an electrode mounted to the distal end of the lead body and a second elongated conductive coil is also located within the lead body and extends to a transition point proximal to the distal end of the first coil conductor, the second coil terminating within the lead body and insulated from the exterior of the lead body. The first conductive coil has a generally straight configuration and the distal portion of the second coil is formed to define a curve.
