Lead construction for deep brain stimulation
First Claim
1. A stimulation lead extending from a proximal end to a distal end, the lead comprising:
- a plurality of electrodes disposed along the distal end of the lead;
a plurality of terminals disposed along the proximal end of the lead;
an elongated body separating the plurality of electrodes from the plurality of terminals, the elongated body comprisingan outer tube of insulative material, anda cog-shaped conductor guide disposed within, and separate from, the outer tube and extending from the proximal end of the lead to the distal end of the lead, the conductor guide comprising an outer surface, a central core, and a plurality of protrusions extending outward from the central core, wherein the plurality of protrusions and the outer tube define a plurality of pocket regions along the outer surface of the conductor guide with a one of the plurality of pocket regions defined between each pair of adjacent protrusions of the plurality of protrusions; and
a plurality of conductors disposed within the plurality of pocket regions with at least one conductor disposed in each of the plurality of pocket regions, each conductor coupling at least one of the plurality of electrodes to at least one of the plurality of terminals.

Abstract
A stimulation lead extends from a proximal end to a distal end and includes a plurality of electrodes disposed along the distal end of the lead; a plurality of terminals disposed along the proximal end of the lead; and an elongated body separating the plurality of electrodes from the plurality of terminals. The elongated body includes an outer tube of insulative material, and a cog-shaped conductor guide disposed within the outer tube. The conductor guide includes a central core and a plurality of protrusions extending outward from the central core. The plurality of protrusions and the outer tube define a plurality of pocket regions. The stimulation further includes a plurality of conductors disposed within the plurality of pocket regions, each conductor coupling at least one of the plurality of electrodes to at least one of the plurality of terminals.
