Lead with contact end conductor guide and methods of making and using
First Claim
1. An electrical stimulation lead extending from a proximal end to a distal end and having a circumference, the lead comprising:
- an end conductor guide disposed at the proximal or distal end of the lead, the end conductor guide having a first end, a second end, a generally cylindrical shape, a length, and an exterior surface, the end conductor guide defining a plurality of conductor tracks formed in the exterior surface and extending longitudinally from the first end at least partway along the length of the end conductor guide, the end conductor guide further defining protrusions between adjacent conductor tracks giving the end conductor guide a cog-shaped cross-section at the first end, wherein each of the conductor tracks extends a different distance along the length of the end conductor guide;
a plurality of electrodes disposed along the distal end of the lead, wherein each electrode is a cylindrical ring electrode extending around the circumference of the lead;
a plurality of terminals disposed along the proximal end of the lead, wherein each terminal is a cylindrical ring terminal extending around the circumference of the lead, wherein the plurality of terminals are disposed over the end conductor guide when the end conductor guide is disposed at the proximal end of the lead and the plurality of electrodes are disposed over the end conductor guide when the end conductor guide is disposed at the distal end of the lead;
an elongated lead body extending from the plurality of electrodes to the plurality of terminals; and
a plurality of conductors coupling the plurality of electrodes to the plurality of terminals, each of the conductors comprising an end portion that is disposed within one of the plurality of conductor tracks of the end conductor guide.

Abstract
An electrical stimulation lead includes a cog-shaped conductor guide disposed either at the proximal end or the distal end of the lead. The cog-shaped conductor guide includes a central core and multiple protrusions extending outwards from the core. Conductor tracks are defined within the cog-shaped conductor guide between adjacent protrusions. Electrodes are provided along the distal end of the lead, terminals are provided along the proximal end of the lead, and conductors couple the electrodes to the terminals. An elongated lead body extends from the electrodes to the terminals of the lead. Each of the conductors has an end portion positioned within one of the conductor tracks of the cog-shaped conductor guide.
