Implantable growth tissue stimulator and method of operation
First Claim
1. An implantable tissue growth stimulator having a status, said stimulator comprising:
- first and second plate electrodes, having first and second voltages respectively, for subcutaneous implantation a predetermined distance from a tissue site;
an elongate member of elastomer for generally maintaining a predetermined distance between said first and second electrodes;
a receiver for receiving a remotely generated instruction;
a driver coupled to said first and second plate electrodes for generating an alternating current between said first and second electrodes, said alternating current operative to stimulate tissue growth at the tissue site;
a driver controller for adjusting a parameter of said alternating current in response to the remotely generated instruction; and
a status generator for generating said status.

Abstract
A hand-held programmer/monitor (500) for programming and monitoring an implantable tissue growth stimulator (10) is provided. The stimulator (10) includes circuitry (46) for implementing selected operations in response to a down-link signal transmitted by the programmer/monitor (500). The stimulator (10) also includes circuitry (14) for transmitting up-link signals to the programmer/monitor (500). The programmer/monitor (500) includes a control circuit (518) for generating the down-link signal. The control circuit (518) also processes the up-link signal to monitor the status of the implantable tissue growth stimulator (10). The programmer/monitor (500) also includes a transmit/receive circuit (514) for transmitting the down-link signal to and for receiving the up-link signal from the implantable tissue growth stimulator (10). The transmit/receive circuit (514) also couples the up-link signal to the control circuit (518).
