Patent ID: 7769460

Claim:
An implantable electrical stimulation system comprising: a sensing device adapted to be implanted outside of a bladder; a lead having an electrical conductor therein and adapted to extend from the sensing device into an interior of the bladder via penetration of a wall of the bladder; a sensor, adapted to be carried at a distal end of the lead and positioned within the interior of the bladder, that senses a condition within the interior of the bladder; a processor within the sensing device that generates information based on the sensed bladder condition; and an implantable stimulator that delivers stimulation therapy based on the information, wherein the implantable stimulator and the sensing device are separate devices, and wherein the implantable stimulator and the sensing device each comprise respective wireless communication circuitry and the sensing device wirelessly communicates the information generated based on the sensed bladder condition to the implantable stimulator via the wireless communication circuitry.
