InterStim II Neurostimulator
The implanted InterStim™ II system electrically stimulates the sacral nerve which is thought to normalize neural communication between the bladder and brain1 and between the bowel and brain.2
InterStim Therapy for Urinary Control is indicated for the treatment of urinary retention and the symptoms of overactive bladder, including urinary urge incontinence and significant symptoms of urgency-frequency alone or in combination, in patients who have failed or could not tolerate more conservative treatments.
InterStim Therapy for Bowel Control is indicated for the treatment of chronic fecal incontinence in patients who have failed or are not candidates for more conservative treatments.
The InterStim II neurostimulator streamlines the implant procedure with a design that eliminates the need for the lead extension and uses fewer set screws.
InterStim II model 3058 has FDA-approved labeling for 1.5 Tesla MRI head scans.
