Development of the Skeletal Muscle Stimulator with Resonant Type Transmission Function

In order to investigate the technique of cardiac assistance using skeletal muscle (Cardiomyoplasty) we are developing an implantable skeletal muscle stimulator that responds to muscle fatigue. The stimulator has a resonant circuit to transmit internal information using the carrier waves from the external program head. The stimulator can also control the synchronization ratio automatically using the peak value of the impulse response from an acceleration sensor to estimate muscle fatigue. In this series of animal experiments we verified the functions of both data transmission by the resonant circuit and automatic control of the synchronization ratio. Our results suggest that the stimulator can be used to automatically control muscle stimulation in Dynamic Cardiomyoplasty
