Control of urge incontinence

In a method of treating urinary incontinence, fecal incontinence, constipation and/or pathological retention of urine, at least one electrode of a lead is implanted in contact with a pelvic muscle of the patient. A proximal end of the lead is connected to a hermetically sealed implantable stimulator device configured to apply an electrical waveform through the at least one electrode. The electrical waveform is delivered from the stimulator device to the pelvic muscle through the lead and the at least one electrode. The electrical waveform provides at least partial relief from at least one of urinary incontinence, fecal incontinence, constipation and pathological urine retention.
