Abstract:
1. A method of reducing muscle stimulation during electrosurgical procedures comprising: treating a target tissue with an electrosurgical wand comprising a plurality of active electrodes on a distal end of the electrosurgical wand, each of the plurality of active electrodes intermittently exposed to a rectifying electrical phenomenon; charging a first capacitance in series with a first electrode of the plurality of active electrodes, the charging during periods of time when the rectifying electrical phenomenon is proximate the first electrode; charging a second capacitance, distinct from the first capacitance, the second capacitance in series with a second electrode of the plurality of active electrodes, the charging during periods of time when the rectifying electrical phenomenon is proximate the second electrode; charging a third capacitance, distinct from the first and second capacitances, the third capacitance in series with a third electrode of the plurality of active electrodes, the charging during periods of time when the rectifying electrical phenomenon is proximate the third electrode; and then discharging, through the first electrode, the first capacitance, during the step of charging the second capacitance.
