Implantable nerve signal sensing and stimulation device for treating foot drop and other neurological disorders

摘要

The totally implantable neural stimulation system comprises the closed loop control unit (50) of Event triggered, it detects physiological event by one or more neural cuff electrodes from nerve signal, the for example generation that heel contacts or tiptoe is mentioned incident, and neurad is sent boost pulse, to produce the physiological reaction of expection.This stimulating system comprises: low noise low-power nerve signal amplifier (180); Accelerometer (156), it detects the orientation angles of patient's thigh; And battery powered processor (150), it is the assembly power supply in system optionally so that so that the minimized mode of the power of battery detect described physiological event and send described boost pulse.
