Abstract
An apparatus and method for neuromodulation therapy for urinary incontinence and urological disorders comprises an implantable lead-receiver, and an external stimulator having a power source, controlling circuitry, and predetermined programs. The stimulator further includes a primary coil which inductively transfers electrical signals to the lead-receiver, which is also in electric contact with the sacral nerves. The external stimulator emits electrical pulses to stimulate the sacral plexus according to a predetermined program. In a second mode of operation, an operator may manually override the predetermined sequence of stimulation.
