Percutaneous Surgical lead body
First Claim
1. An implantable medical lead comprising:
- a first lead body having at least one first electrode extending around the first lead body;
a second lead body attached to the first lead body in at least one location, the second lead body having at least one second electrode; and
a substantially non-dissolvable, non-conductive coating applied to a portion of either of the first or second electrode for directing a stimulation signal away from that portion, whereby the medical lead may be percutaneously implanted.

Abstract
There is disclosed a surgical lead comprising two percutaneous lead bodies bonded together. The inventive lead body results in the equivalent of a surgical lead body with columns of electrodes either adjacent to or offset from each other. A bridge of urethane material is used to bond together the percutaneous lead bodies and still provide suitable flexibility of the lead. The surface of the electrodes may be coated, in part, with a suitable non-conductive coating to effectively direct the electrical stimulation signals toward the targeted stimulation area. Significantly, the resulting lead is sized to fit within a needle having a similar cross-section, thereby permitting the percutaneous implantation of the inventive lead.
