UTAH SLANTED ELECTRODE ARRAY PUDENDAL NERVE STIMULATOR

Bladder dysfunction affects 17 million Americans and is particularly common in patients with spinal cord injuries and multiple sclerosis. Current treatments, while effective, have major side effects including infection, urethral damage, and loss of peripheral sensation.

The pudendal nerve stimulator treats bladder dysfunction by enabling push-button urination control. The nerve stimulator consists of a Utah Slanted Electrode Array implanted into the pudendal nerve that selectively contracts and relaxes the two major muscle groups associated with urination. A remote device signals the array to contract the bladder muscle, while restricting the urethral sphincter to facilitate urination. The device can be inserted using minimally-invasive surgery and eliminates the need for catheterization and the major side effects associated with current bladder dysfunction treatments.
