Method of manufacturing an implantable lead
First Claim
1. A method of manufacturing an implantable lead, comprising:
- extruding a lead body having a proximal end, a distal end, an internal core portion, an external sheath portion, a stylet lumen, and at least one conductor lumen in the internal core portion positioned near an outer surface of the internal core portion such that a web region is formed between the conductor lumen and the outer surface of the internal core portion;
inserting the internal core portion within the external sheath portion; and
creating at least one axial slit in the web region of the internal core portion between the conductor lumen and the outer surface of the internal core portion, the axial slit being generally parallel to the conductor lumen.

Abstract
An implantable lead body for a medical device with improved conductor lumens separates and insulates conductors while permitting access to the conductors through the implantable lead outer surface. The implantable lead comprises a lead body, a stylet lumen, at least one conductor lumen, and at least one axial slit in the lead body. The lead body has a proximal end, a distal end, an internal portion, and an external portion. The stylet lumen is formed in the internal portion. The conductor lumen is formed in the internal portion and positioned near an outer surface of the internal portion such that there is only a web between the conductor lumen and the outer surface of the internal portion. The axial slit is formed in the lead body distal end between the conductor lumen and the outer surface of the internal portion.
