Abstract
A system for heating a site in a patient's body includes a transformer having a primary winding and a secondary winding, the secondary winding having at least one center tap to provide a patient reference and at least two sources of radio frequency (RF) energy, the two sources of RF energy being out of phase with each other. A group of electrodes is connected to the sources of RF energy provided by the secondary winding to be simultaneously energized. The arrangement is such that there are more active electrodes connected to one of the sources of RF energy than another of the sources of RF energy with the energy supplied to one active electrode being out of phase with the energy supplied to an adjacent active electrode.

A system for heating a site in a patient's body, the system including:
- a transformer having a primary winding and a secondary winding, the secondary winding having at least one tap to provide a patient reference and at least two sources of radio frequency (RF) energy, the at least two sources of RF energy being out of phase with each other;
- and
- a group of electrodes connected to the at least two sources of RF energy provided by the secondary winding to be simultaneously energized, the arrangement being such that there are more active electrodes connected to one of the at least two sources of RF energy than another of the sources of RF energy with the energy supplied to one active electrode being out of phase with the energy supplied to an adjacent active electrode.
A system for heating a site in a patient's body, the system including:
- a transformer having a primary winding and a secondary winding, the secondary winding having at least one tap to provide a patient reference and at least two sources of radio frequency (RF) energy, the at least two sources of RF energy being out of phase with each other;
- and
- a plurality of electrodes connected to the at least two sources of RF energy provided by the secondary winding to be simultaneously energized, with multiple active electrodes being connected to one of the sources of RF energy and a different number of active electrodes connected to another source of RF energy and the energy supplied to each of the multiple active electrodes being of the same phase but out of phase with the energy supplied to each of the different number of active electrodes.
A method of heating a site in a patient's body, the method including:
- providing a transformer having a primary winding and a secondary winding, the secondary winding having at least one tap to provide a patient reference and at least two sources of radio frequency (RF) energy, the at least two sources of RF energy being out of phase with each other;
- and
- connecting a group of electrodes to the at least two sources of RF energy provided by the secondary winding to be simultaneously energized, the arrangement being such that there are more active electrodes connected to one of the at least two sources of RF energy than another of the at least two sources of RF energy with the energy supplied to one active electrode being out of phase with the energy supplied to an adjacent active electrode.
