BACKGROUND The use of functional neurosurgical implants has increased over the past 10 years. PlasmaBlade is an innovative electrosurgical appliance harnessing pulsed radiofrequency (RF) energy. Our aim was to assess the risk of damage to neuromodulation hardware during PlasmaBlade dissection. MATERIALS AND METHODS A simulated setting with chicken breast threaded with different hardware and PlasmaBlade used in three configurations. . Post dissection, the wires were inspected naked eye and under an operating microscope. The induced current was assessed contemporaneously using an oscilloscope. RESULTS Five surgeons tested the PlasmaBlade at different generator settings. Sixty dissections were undertaken. No structural damage or induced current was identified at CUT 3/4, COAG 5. At CUT 6, COAG 5 and during dissection in a perpendicular orientation with prolonged hardware contact, opacification of insulation material occurred in 15/20 dissections. There was no dissolution of insulation even at this setting. On deviation from Medtronic advice, hardware damaged occurred if one was reckless with the PlasmaBlade. CONCLUSION When using the recommended settings and operational technique, PlasmaBlade dissection did not cause any damage to implant wiring/tubing in this simulated setting. This report seeks to add to clinical data suggesting PlasmaBlade is safe for dissection around deep brain stimulator (DBS), vagal nerve stimulator (VNS), and spinal cord stimulator (SCS) hardware.
