System and method for providing medical electrical stimulation to a portion of the nervous system
First Claim
1. A system for providing medical electrical stimulation to at least a portion of the nervous system comprising:
- a rigid hollow needle having a lumen;
a flexible lead body disposed within the lumen of the needle, the lead body having an insulated coiled proximal section and an electrode section, the proximal section comprising a coiled, insulated conductor, the conductor in the electrode section comprising coils having no outer insulation disposed thereover, the electrode section further comprising a crimp core to which a distal end of the coiled conductor is crimped, the electrode section having a surface area of about 11 sq. mm.

Abstract
A system and method for providing medical electrical stimulation to a portion of the nervous system. The system includes a rigid hollow needle having a lumen, a flexible lead body disposed within the lumen of the needle, the lead body having a insulated coiled proximal section and an electrode section, the proximal section comprising a conductor which is coiled and insulated, the electrode section comprises a portion of the coiled conductor which is not insulated. In an alternative embodiment the electrode section features a crimp core around which a distal end of the coiled conductor which is not insulated is crimped, the rigid hollow needle is metal but which is partially covered along its outer surface with an insulation. In still further embodiments the flexible lead body has a stylet lumen therein and the lead body also has a connector pin for electrically connecting the electrical conductor to a pulse generator. Preferably this connector pin located on a proximal end of the lead body and having a diameter no greater than the inner diameter of the needle. A method of providing temporary electrical stimulation to the sacral nerve is also disclosed.
