Abstract
A lead is configured and arranged for brain stimulation. The lead includes a proximal end and a distal end. The proximal end includes a plurality of terminals disposed at the proximal end. The distal end has a non-circular transverse cross-sectional shape and includes a plurality of electrodes disposed at the distal end. A plurality of conductive wires electrically couple at least one of the plurality of electrodes to at least one of the plurality of terminals.
Claims20
A lead configured and arranged for brain stimulation, the lead comprising:
- a proximal end comprising a plurality of terminals disposed at the proximal end;
- a distal end having a non-circular transverse cross-sectional shape, the distal end comprising a plurality of electrodes disposed at the distal end;
- and
- a plurality of conductive wires, each of the plurality of conductive wires electrically coupling at least one of the plurality of electrodes to at least one of the plurality of terminals.
A lead configured and arranged for brain stimulation, the lead comprising:
- a proximal end comprising a plurality of terminals disposed at the proximal end;
- a distal end comprising a plurality of electrodes disposed at the distal end, wherein the distal end defines a hollow interior region that is open at the distal end, the hollow interior region having a longitudinal length, an outer surface external to the hollow interior region, and an inner surface lining the sides of the hollow interior region;
- and
- a plurality of conductive wires, each of the plurality of conductive wires electrically coupling at least one of the plurality of electrodes to at least one of the plurality of terminals.
A method for stimulating patient brain tissue, the method comprising:
- implanting a lead into a brain of a patient, the lead comprising a plurality of electrodes disposed on a distal end, the distal end having a non-circular transverse cross-sectional shape, the plurality of electrodes electrically coupled to a plurality of terminals disposed on a proximal end, a plurality of conductive wires electrically coupling at least one terminal to at least one electrode;
- disposing the proximal end of the lead into a connector, the connector configured and arranged for receiving the proximal end of the lead, the connector comprising a plurality of connective contacts that electrically couple to at least one of the plurality of terminals, the connector electrically coupled to a control module;
- and
- providing electrical signals from the control module to electrically stimulate patient tissue using at least one of the plurality of electrodes disposed on the distal end of the lead.
