Abstract:
1. Apparatus for producing a dorsiflexion of the foot of a patient, comprising: a combined sensing and stimulation electrode device having neurosense and stimulation electrode means capable of sensing a nerve signal from a peripheral nerve and stimulating peripheral motor nerve fibres, wherein said neurosense and stimulation electrode means are adapted to be implanted at a location on a single nerve above the knee of the patient through a single surgical incision; means for receiving and processing the nerve signals sensed in from said location of the patient above the knee of the patient to identify a signal indicative of the timing of heel strike and heel lift of the patient and for producing a control signal in response thereto, and means for operating said neurosense and stimulation electrode means in response to the control signal to produce a stimulation of the peripheral motor nerve fibres at said location of to produce dorsiflexion of the foot of the patient.
