Dual patient controllers
Devices, systems, and methods incorporate the most-used functions of an electrical stimulator's controller into a small, thin pocket controller that is not only comfortable to carry in a pocket, but can also be attached to a key ring, lanyard, or other such carrying device for ease of daily use. A separate patient controller charger is used to charge and control the implanted medical device.
