Abstract

The invention discloses a programmable implantable hearing aid including built-in electronics being in wireless communications with a hand-held programmer. The programmer transmits digital code signals of the type including RF, infrared and ultrasonic, based on selected parameter settings. A receiver accepts the signals for transmission to an input transducer in the middle ear. The input transducer collects the middle ear'"'"'s response to the signals and transmits it to a circuit in the implanted hearing aid. The circuit searches for specific programming patterns and decodes the signals to effectuate the desired adjustment in the hearing aid. The conditioned signals are then transferred to an output transducer to operate the device at the adjusted signal level and condition. The invention enables both a patient and doctor to make unlimited number of adjustments in the implanted hearing aid without invasive surgery.
