Single and multi-polar implantable lead for sacral nerve electrical stimulation
First Claim
1. An implantable medical lead for non-direct contact electrical stimulation of the sacral nerves, comprising, in combination:
- a lead body having a distal end and a proximal end, the distal end having a first electrode contact and a second electrode contact,the first electrode contact having a length of between 0.10 inches and 1.5 inches extending longitudinally from a position at the distal end toward the proximal end, and the first electrode contact comprises a coiled wire,the second electrode contact having a length of between 0.03 to 1.00 inches, extending longitudinally from a point beyond the first electrode contact at least 1.00 inches from the distal end toward the proximal end and, the first and second electrode contact arranged and sized such that the first electrode does not longitudinally overlap with the second electrode contact, and the second electrode contact comprises a solid surface material,whereby the first and second electrode contacts of the lead body provide stimulation to the sacral nerve without necessarily being in direct contact with the sacral nerves.

Abstract
An implantable medical lead for stimulation of the sacral nerves comprises a lead body which includes a distal end and a proximal end, and the distal end having at least one electrode contact having a length of between 0.10 and 1.50 inches extending longitudinally from the distal end toward the proximal end. The lead body at its proximal end may be coupled to a pulse generator, additional intermediate wiring, or other stimulation device. The implantable medical lead can comprise a first and second electrode contacts. The second electrode contact has a length of between 0.030 and 1.00 extending longitudinally from a point approximately 1.00 from the distal end toward the proximal end. The first and second electrode contacts do no overlap longitudinally. The implantable lead is implanted by taking the lead and implanting near the sacral nerves and then connecting to a pulse generator.
