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 oneor more nerve cuff electrodes and delivers stimulation pulses to a nerve toproduce a desired physiological response, The stimulation system includes alow-noise, low-power nerve signal amplifier (180), accelerometers (156) thatdetect the orientation angle of a patient~s thigh and a battery poweredprocessor (150) that selectively powers components in the system to detectsaid physiological events and deliver said stimulation pulses with a minimumof battery power.
