Patent ID: 8369963

Claim:
A stimulator device for providing a simulation current to the tissue of a patient, comprising: a body for the device; a plurality of electrodes coupled to the body, comprising: an anode, wherein the anode is coupled to an anode current path within the body, and a plurality of cathodes, wherein each cathode is coupleable to a single associated cathode current path within the body; selection circuitry for coupling one of the cathodes to its associated cathode current path, thereby selecting that cathode as an active cathode and that cathode current path as an active cathode current path; and a single decoupling capacitor within the body, wherein the anode current path comprises the decoupling capacitor, and wherein none of the cathode current paths comprise a decoupling capacitor, wherein the stimulation current flows from the anode current path to the active cathode current path.
