LEAD INCLUDING A HEAT FUSED OR FORMED LEAD BODY
First Claim
1. A lead comprising:
- a multi-lumen lead body extending from a lead proximal end portion to a lead distal end portion and having a lead intermediate portion therebetween, the lead body including,at least one heat-formed bias portion at the lead intermediate or distal end portions, andan orientation and fixation curve portion proximal or distal to the heat-formed bias portion, the orientation and fixation curve including one or more heat-formed polymers;
at least three tissue sensing/stimulation electrodes disposed along the lead intermediate or distal end portions;
one or more terminal connections disposed along the lead proximal end portion;
one or more conductors contained within the multi-lumen lead body extending between the at least three tissue sensing/stimulation electrodes and the one or more terminal connections.

Abstract
An implantable lead comprises a lead body extending from a lead proximal end portion to a lead distal end portion. In one example, the lead body may comprise a heat-formed bias portion. In another example, an outer insulator is fused to the lead body. In such an example, a lead body fusable plug may be disposed distal to at least one conductor. In another example, the lead comprises an inner boot and an outer boot fused to one another. In another example, the lead includes an atraumatic tip fused to the lead distal end portion. In another example, the lead body is reducable in size using heat shrink tubing. In yet another example, two or more lead sections may be interconnected using an outer insulator fused to the respective lead bodies. In a further example, a stiffener member is fused to the lead body adjacent a lead component.
