InterStim (Medtronic)

InterStim, developed by Medtronic, is a medical device used to treat overactive bladder, urinary retention, and some chronic bowel issues. It works by delivering gentle electrical pulses to specific nerves via a small implant placed under the skin near the sacrum (lower back). This stimulation helps regulate nerve signals that control bladder and bowel functions, reducing symptoms like urgency, leakage, or retention. The device can be adjusted externally to optimize effectiveness and is typically used when other treatments haven't worked. InterStim offers a minimally invasive option to improve quality of life for individuals with complex bladder or bowel conditions.
