Video of an InterStim® therapy procedure. InterStim® therapy is indicated for the treatment of urinary retention and the symptoms of overactive bladder in patients who have failed or could not tolerate more conservative treatments. More specifically called sacral modulation, InterStim® involves implanting a programmable device in the bowel or bladder to relieve severe bladder or bowel control problems. The device works by delivering a small pulse to nerves controlling the bladder or bowel. This is a replay of a live webcast originally aired on 12/4/08.
