ELECTRICAL STIMULATION SYSTEM AND METHOD USING MULTI-GROUP ELECTRODE ARRAY
First Claim
1. An electrical stimulation system using multi-group electrode array, comprising:
- an implant body having an electrode carrying surface;
an electrode array provided on the electrode carrying surface of the implant body;
the electrode array comprising a plurality of electrode groups, each of the electrode groups including a plurality of electrodes, and each of the electrodes having an independent power supply control; and
an electrode controller for receiving a control signal to drive a set of at least two corresponding electrodes, and powers supplied to the set of corresponding electrodes being regulated by the corresponding independent power supply controls thereof to thereby generate a virtual channel between the set of corresponding electrodes through interaction of powers supplied to the set of corresponding electrodes.

Abstract
An electrical stimulation system and method using multi-group electrode array are disclosed. The electrical stimulation system comprises an implant body having an electrode carrying surface, an electrode array provided on the electrode carrying surface, and an electrode controller. The electrode array comprises a plurality of electrode groups, each of which includes a plurality of electrodes, and each of the electrodes has an independent power supply control. The electrode controller receives a control signal to drive a set of at least two corresponding electrodes, which is selected from the electrodes of the same electrode group and two adjacent electrode groups. Powers supplies to the set of corresponding electrodes may be regulated by the independent power supply controls thereof, so as to generate a virtual channel between the set of corresponding electrodes through interaction of powers supplied to the set of corresponding electrodes.
