The present invention relates to a wireless handheld device that is
configured to communicate with an implanted device using inductive
telemetry. The handheld device is preferably battery operated and
includes a battery powered controller and a battery powered inductive
coil. The inductive coil is configured to communicate with an inductive
coil of the implanted device using inductive telemetry. The handheld
device may include one battery voltage source that powers both the
controller and the inductive coil, or multiple battery voltage sources to
power the controller and inductive coil separately. In a single battery
voltage source embodiment, the voltage may be amplified or reduced to
meet the power needs of the controller and inductive coil. In a multiple
battery voltage source embodiment, the voltage sources may be combined to
increase the power output requirements of the inductive coil.
