Abstract:
A system for delivering energy to any one of a plurality of tissue regions at a biological site within a biological body, said system comprising:at least one primary electrode adapted to be positioned adjacent tiny one of the plurality of tissue regions; a plurality of secondary electrodes adapted to be positioned about the biological site such that any one of the plurality of tissue regions is interposed between at least one of the secondary electrodes and the at least one primary electrode; a power generator adapted to provide power to the at least one primary electrode; a switching device adapted to couple anyone of the secondary electrodes to an electrical device, the electrical device adapted to maintain the coupled secondary electrode at a voltage level different from the primary electrode such that current flows from the primary electrode through the tissue region to the coupled secondary electrode; and a controller programmed to, based upon an electrical-based measurement between the secondary electrodes and the at least one primary electrode, select one of the secondary electrodes for coupling with the electrical device and to command the switching device to couple the selected secondary electrode to the electrical device.
