Systems and methods for patient control of stimulation systems
First Claim
1. A method comprising:
- transmitting a radio frequency magnetic field from a charging coil of a recharging module positioned proximate to an implanted medical device to transcutaneously recharge a power supply of the medical device, wherein the recharging module is at least partially disposed in a shell of a medical device controller; and
communicating, using a telemetry module at least partially disposed in the shell, with the implanted medical device via non-inductive wireless telemetry to receive status information from the medical device while the recharging module recharges the power supply of the implanted medical device, wherein the medical device controller at least one of adjusts a magnitude of the radio frequency magnetic field or instructs a user to reposition the charging coil based on the status information, and wherein the charging coil is at least partially disposed outside of the shell.

Abstract
Provided is a portable controller and associated method that provides a patient or caregiver the ability to recharge and alter the parameters of an implanted medical device, while allowing the patient substantially unobstructed mobility. To enable mobility, the controller may be worn on a belt or clothing. The controller also allows the patient to turn device stimulation on and off, check battery status, and to vary stimulation parameters within ranges that may be predefined and programmed by a clinician. The controller communicates with the medical device to retrieve information and make parameter adjustments using wireless telemetry, and it can send and receive information from several feet away from the implanted medical device. Charging of a battery contained in the implanted medical device is achieved via an inductive radio frequency link using a charge coil placed in close proximity to the medical device.
