Approximately 30% of men wiht erectile dysfunction do not respond to oral medications. One of the primary reasons in neurological damage. This may be do to diabetes, spinal cord damage, nerve damage from a prostatectomy, or other causes.

A new implantable device allows men with neurological damage to achieve an erectile by bypassing the damaged nerves, and directly stimulating the nerves in the penis. A battery-powered neuro-stimulator is implanted in the pelvic cavity, and triggered by a remote-control signal. The first successful implantation of the device, called the CaverSTIM, was conducted in August, 2023.

The device is based on studies showing that electrostimulation of the cavernosal nerve can induce and maintain penile erection.
