Controlled monopolar and bipolar application of RF energy
First Claim
1. A system comprising:
- at least two target electrodes and at least one return electrode spaced outwards from said at least two target electrodes;
at least two RF power sources in electrical communication with said electrodes and operative to generate RF energy waveforms to said at least two target electrodes;
a controller in operative communication with said at least two RF power sources to control delivery of RF energy in a monopolar mode, a bipolar mode or a combined monopolar and bipolar mode, wherein in said monopolar mode at least one of said at least two target electrodes is energized by one of said RF power sources and cooperates with said at least one return electrode to deliver monopolar RF energy towards a first spatial region, and wherein in said bipolar mode said at least two target electrodes are energized by said at least two RF power sources to deliver bipolar RF energy between said at least two target electrodes in a second spatial region different from said first spatial region, and wherein in the combined monopolar and bipolar mode the at least two RF power sources deliver RF energy to the at least two target electrodes such that energy is delivered between the at least two target electrodes as well as between the at least two target electrodes and the at least one return electrode; and
an actuator operative to cause relative motion between said at least two target electrodes and surrounding tissue.
