A multi-purpose, implantable stimulator for use in an FES system includes a housing, implantable into a patient's body. The housing contains a receiving device and a control unit, the control unit receiving signals from the receiving device which, in turn, receives signals transcutaneously from a controller arranged externally of the patient's body. A plurality of leads extend from the housing, the leads being arranged in separate bundles of discrete leads, each bundle being associated with a particular site of the patient's body.

FES stimulator having multiple bundled leads

A multi-purpose FES system includes a multi-function, implantable stimulator for stimulating different sites in a patient's body. The stimulator includes a control unit and a receiving device. The stimulator further has a plurality of bundles of electric leads connected to the control unit, each lead terminating in at least one electrode to provide a plurality of discrete groups of electrodes associated with each site. Each group of electrodes is operable to stimulate its associated site in the patient's body, under the action of stimulation signals from the control unit, the control unit receiving signals from the receiving device. A transmitter is arranged externally of the patient's body for supplying signals transcutaneously to the receiving device of the stimulator. A controller is in communication with the transmitter via a communications interface unit.

Multi-purpose FES system

A multi-purpose, functional electrical stimulation (FES) system 10 includes an implantable stimulator unit 12 for stimulating a plurality of different sites in a patient's body 14. A transmitter 20 is arranged externally of the patient's body 14 for supplying signals transcutaneously to the stimulator unit 12. A controller 16 is in communication with the transmitter 20. At least one implantable switching node 26 has an input terminal 30 in electrical communication with the stimulator unit 12 and a plurality of output terminals to each of which one of a further switching node 26 and a stimulating element 24 is connected. The switching node 26 including addressing circuitry 44 for switching at least one output terminal into electrical connection with the input terminal 30 of the switching node 26 in response to a control signal received from the controller 16 via the stimulator unit 12.
