Abstract: A medical device may include an electrosurgical hand piece. The electrosurgical hand piece may have a housing with a proximal end, a distal end, and a chamber proximate the proximal end. The chamber may be configured to releasably retain and electrically couple with a power source. The electrosurgical hand piece may also include a treatment delivery element configured to releasably couple to the distal end of the housing. The treatment delivery element may be configured to communicate with the power source and deliver biphasic pulsed field ablation. The medical device may also include a charging element which may charge the power source using inductive charging or near-field (RF) wireless charging.
