METHOD AND SYSTEM OF REDUCTION OF LOW FREQUENCY MUSCLE STIMULATION DURING ELECTROSURGICAL PROCEDURES

摘要

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.
