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 was developed to offer physicians a second choice of neurostimulators and to address a wider range of patient needs. The InterStim II neurostimulator is 37% smaller by displaced volume and almost 50% lighter by weight (22 g versus 42 g) than the InterStim neurostimulator model 3023. The InterStim II neurostimulator is intended for patients who will benefit from the use of a smaller implanted device, and who experience symptom control with low to moderate neurostimulation parameters.
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.

While the precise mechanism of action of SNM has not been fully established, efficacy has been proven in clinical studies.
