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.

Method of manufacturing an implantable lead

An implantable neurological stimulation lead with improved stylet handle comprises a lead body, at least one conductor, at least one electrical contact, at least one electrode, a stylet wire, and a stylet handle. The lead body has a body proximal end, a body distal end, and a stylet lumen. The conductor is contained in the lead and extends from the body proximal end to the body distal end, and the conductor is electrically insulated. The electrical connector is carried on the body proximal end and electrically connected to the conductor. The electrode is carried on the body distal end and electrically connected to the conductor. The stylet wire is configured for insertion into the stylet lumen to stiffen the lead body. The stylet handle is selectively coupled to the stylet wire. The stylet handle has a lead carrier and at least one gripper carried in the lead carrier configured to grip the lead body at a selected point along the lead body or lead proximal end.
