Medical electrical stimulation system using an electrode assembly having opposing semi-circular arms

A system for providing medical therapy comprising:

• a lead body comprising means for coupling the lead to an electrical stimulator, an elongated electrical conductor, an elongated insulative sheath for electrically insulating the elongated electrical conductor, and a resilient hinge disposed near a distal end of the lead body;
• a first curved cuff operably connected to the hinge;
• an electrode disposed on the first cuff, the electrode being electrically connected to the elongated conductor;
• a second curved cuff operably connected to the hinge, and
• wherein in a closed position the hinge biases the first curved cuff towards the second curved cuff, the hinge further comprising means for spreading the first cuff apart from the second cuff so that the hinge assumes an open position;
• wherein the spreading means further comprises a divergent lead body and an implant tool disposed around a portion of the lead body, the implant tool comprising a first surface configured to engage the hinge and spread the first and second cuffs apart.
