摘要

A fully implantable nerve stimulation system includes an event-triggered, closed loop control unit (50) that detects physiological events, e.g. occurrence of heel contact or toe lift event, from nerve signals through one or more nerve cuff electrodes and delivers stimulation pulses to a nerve to produce a desired physiological response, The stimulation system includes a low-noise, low-power nerve signal amplifier (180), accelerometers (156) that detect the orientation angle of a patient’s thigh and a battery powered processor (150) that selectively powers components in the system to detect said physiological events and deliver said stimulation pulses with a minimum of battery power.
