It is powered by a hermetically sealed hybrid cathode silver vanadium oxide (HCSVO) single-cell battery. To further protect the neurostimulator components from body fluids, the electronics and power source are hermetically sealed within an oval-shaped titanium shield. The neurostimulator case has an external insulating coating to prevent skeletal muscle stimulation at the neurostimulator implant site. An uninsulated area on one side of the neurostimulator (etched identification side) forms the indifferent electrode. The uninsulated side should be positioned away from muscle tissue. The neurostimulator has a self-sealing connector assembly with a corrosion-resistant titanium alloy body & titanium setscrews. Securing the lead system requires the use of a torque wrench which is packaged with the neurostimulator.

Instructions for use Implanting physicians should have experience in the surgical and/or implantation techniques for the Enterra II system, operational and functional characteristics of the Enterra II system, 12 English 37800 2014-03 and experience in the continued management of patients by stimulation parameter adjustment. Physicians may contact Medtronic before prescribing or implanting an Enterra II system for the first time, and request a referral to a physician experienced in the use of the Enterra II system. Implanting physicians should be thoroughly familiar with all product labeling.

Cautions:

• When using sharp instruments near the neurostimulator, be extremely careful to avoid nicking or damaging the case, the insulation, or the connector block. Damaging the neurostimulator may require surgical replacement.
• Do not use saline or other ionic fluids at connections, which could result in a short circuit
