  • Patent number: 4024875
    Abstract: A device for the non-invasive programming of an implantable body stimulator. The device includes a power supply and circuitry for generating and transmitting a preselected number of pulses of radio frequency energy. A push-button switch initiates the operation of the pulse-generating circuitry and the power supply is enabled only during an interval of predetermined duration following the initiating of operation of the pulse-generating circuitry. In a preferred embodiment, the power supply includes a power source, such as batteries, and a voltage regulator for establishing a substantially constant supply voltage for all power source voltages above a preselected level. The device may include circuitry for indicating the establishment of the substantially constant supply voltage as well as circuitry for preventing the transmission of any programming pulses upon a failure to establish the substantially constant supply voltage level.
