Percutaneous surgical lead body with directed stimulation
First Claim
1. A controlled orientation stimulation lead for percutaneous implantation, comprising:
- a first lead body having at least one electrode extending around the periphery of the first lead body;
a second lead body attached to the first lead body, the second lead body having at least one electrode extending around the periphery of the second lead body;
a mask applied to a portion of the at least one electrode of either the first or second lead body;
a first lead side formed from the first lead body attached to the second lead body, the first lead side having a first stimulation pattern; and
a second lead side opposite the first lead side having a second stimulation pattern that is orientatable to a preselected stimulation site.

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.

15. A method of implanting a surgical lead body comprising the steps of:
-
providing a first percutaneous lead body having at least one electrode, providing a second percutaneous lead body having at least one electrode, bonding the first percutaneous lead body to the second percutaneous lead body to form the surgical lead body, the surgical lead body defining a first side and a second side, coating either of the first or second side of the surgical lead body with a urethane material, inserting a needle having an opening to a targeted stimulation area, inserting the surgical lead body through the opening of the needle to the targeted stimulation area, and removing the needle from the targeted stimulation area. - View Dependent Claims (16, 17, 18, 19)

20. An implantable medical lead for electrical stimulation at a targeted stimulation area, the medical lead defining a first and second side, comprising:
-
a first lead body having at least one electrode, a second lead body bonded at multiple locations to the first lead body, the second lead body also having at least one electrode, and a non-conductive coating applied to at least a portion of either of the first or second sides of the medical lead, whereby the medical lead may be percutaneously implanted at the targeted stimulation area. - View Dependent Claims (21, 22, 23, 24)
