Patent Images
1. A neurostimulation catheter lead to lie along and stimulate neural tissue comprising:
- a sheath having a distal and proximal end;
at least three in-line electrodes spaced along the exterior of the distal end of the sheath to lie in-line along the neural tissue; and
wherein the electrodes each extend in the range of 90 degress to less than 180 degress about the exterior of the sheath.

Abstract
Various stimulation catheters are disclosed to lie along and stimulate tissue. The electrodes on the leads are various sizes to conserve the battery as well as allowing a more defined area of stimulation. It may also include multiple channels or passages for delivery of drugs, thermal or photonic energy.
