Leads with segmented electrodes and methods of making and using the leads
First Claim
1. A pre-electrode for a stimulation lead, the pre-electrode comprising:
- a substantially-cylindrical pre-electrode body having a proximal end and a distal end, the pre-electrode body comprisingan electrically-conductive central huh having a longitudinal surface,a plurality of connector elements extending radially outward from the longitudinal surface of the central hub, the plurality of connector elements each having a medial end coupled to the central huh and an opposing lateral end, anda plurality of stimulation members each having an inner surface and an outer surface, the inner surface of each of the plurality of stimulation members coupled to the lateral end of at least one of the plurality of connector elements such that each of the plurality of stimulation members is electrically-coupled to each of remaining stimulation members of the plurality of stimulation members solely via the central hub, andwherein the plurality of stimulation members are arranged circumferentially in a single circle around the central hub.

Abstract
A method of making a stimulation lead includes disposing a pre-electrode along a distal end portion of a lead body. The pre-electrode includes a body having a central hub and stimulation members individually coupled to the central hub and extending radially-outward therefrom such that each of the stimulation members is electrically-coupled to each of the remaining stimulation members solely via the central hub. Conductors extending from terminals disposed along a proximal end portion of the lead body are electrically-coupled to each of the stimulation members. Electrically-nonconductive material is disposed around longitudinal surfaces of the central hub with the electrically-nonconductive material abutting inner surfaces of the stimulation members. The central hub is removed from the pre-electrode body to electrically isolate each of the stimulation members from one another, thereby transforming the stimulation members into electrically-isolated segmented electrodes disposed along the electrically-nonconductive material.
