Field Steerable Electrical Stimulation Paddle, Lead System, and Medical Device Incorporating the Same
First Claim
1. A method of manufacturing an implantable electrode paddle adapted to receive an electrical signal from a medical device and generate an electrical field to stimulate selected body tissue, the method comprising the step of:
- assembling an electrode array including a plurality of electrode groups, and a plurality of wires coupled to the electrode array, onto a first insulative substrate having a plurality of windows formed therethrough for transmitting the electrical field to the body tissue, and securing each electrode in a respective window with the electrodes in each group longitudinally spaced between about 0.1 mm and about 10 mm apart.

Abstract
An implantable electrode paddle is adapted to receive an electrical signal from a medical device and generate an electrical field to stimulate selected body tissue. The paddle includes a housing including walls that define an interior space and a plurality of windows formed through at least a first one of the walls for transmitting the electrical field to the body tissue, an electrode array including a plurality of electrode groups, each electrode group including at least two electrodes individually secured in a respective window and spaced between about 0.1 mm and about 10 mm apart, and a plurality of wires, each of the wires being coupled to a respective electrode and routed within the interior space to receive the electrical signal. A lead assembly and an implantable medical device can include the paddle.
