A sterilizable programmer repeater system for retransmission of a programmed code via an RF data link from a pacemaker or defibrillator programmer to an implanted pacemaker or defibrillator which can be used in the operating theater. Coded program information from a remotely placed programmer is data linked by an RF transmitter to a programmer repeater placed externally adjacent to an implanted pacemaker or defibrillator. The received coded program data information is rebroadcast by a transmitter in the programmer repeater to the implanted pacemaker or defibrillator. Coded program data information from the implanted pacemaker or defibrillator is also sent in the reverse direction from the implanted device to the remotely linked placed programmer.
