A device (20) for treating a medical condition is provided, and a surgical procedure for implanting the device is disclosed. The device (20) includes a sensor (44), which is adapted to generate a signal responsive to a state of a patient, and at least one electrode (27), which is adapted to be coupled to a pelvic site of the patient. A control unit (22) is adapted to receive the signal, to analyze the signal so as to distinguish between an imminent stress incontinence event and an imminent urge event, and, responsive to analyzing the signal, to apply an electrical waveform to the at least one electrode (27). In various configurations, the device (20) may be used alternatively or additionally to treat fecal incontinence, interstitial cystitis, chronic pelvic pain, or urine retention.
