IMPLANTABLE LEAD HAVING A LUMEN WITH A WEAR-RESISTANT LINER

摘要

An implantable lead includes a lead body having a proximal end portion and a distal end portion. The lead body includes an insulative member having a lumen extending longitudinally between the proximal end portion and the distal end portion. The lead body also includes a generally tubular helical liner disposed coaxially with the lumen within the insulative member. A pitch of the helical liner varies along the length of the lead. The implantable lead also includes an electrode disposed along the lead body in the distal end portion thereof, and a conductor disposed within the lumen and electrically coupled to the electrode. A terminal connector is coupled to the proximal end portion of the lead body and to the conductor.

1. An implantable lead comprising:
a lead body having a proximal end portion and a distal end portion, the lead body including:
an insulative member having a lumen extending longitudinally through the proximal end portion and the distal end portion; anda generally tubular helical liner disposed coaxially with the lumen within the insulative member, wherein a pitch of the helical liner varies along the length of the lead; an electrode disposed along the lead body in the distal end portion thereof; a conductor disposed within the lumen and electrically coupled to the electrode; and a terminal connector coupled to the proximal end portion of the lead body and to the conductor, the terminal connector configured to provide an electrical and mechanical connection of the implantable lead with an implantable medical device.
