Abstract:
1. A nerve stimulation system comprising: an implantable pulse generator comprising a sensing module and a pace circuit; and an implantable lead comprising a distal end, an electrode array near the distal end, a proximal end including a lead connector end configured to couple the proximal end to the pulse generator, and conductors extending through the lead from the electrode array and caused to be in electrical communication with the sensing module and pace circuit when the proximal end is coupled to the pulse generator, wherein the electrode array comprises at least a first pair of small electrodes and a large electrode in close proximity to each other, the small electrodes and large electrode physically separated from each other by non-conductive spaces extending generally transversely to a longitudinal axis of the lead, wherein, when the conductors are in electrical communication with the sensing module and pace circuit, the first pair of small electrodes are in electrical communication with both the sensing module and the pace circuit and the large electrode is in electrical communication with the pace circuit, but not the sensing module, and wherein the system is configured for spinal cord stimulation and wherein the sensing module is configured to have: a passband of approximately 100 Hz to approximately 2 kHz, a sampling frequency of at least approximately 4 kHz, and a gain of approximately 100 to 1000.
