Abstract:
Reduction of low frequency muscle stimulation during electrosurgical procedures. At least some of the illustrative embodiments are methods including: treating a target tissue with an electrosurgical wand comprising a 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 proximate the first electrode; charging a 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 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 discharging, through the first electrode, the first capacitance, while simultaneously charging the second capacitance.
