Handheld pulsed field ablation generator

A medical system, comprising:

• an electrosurgical hand piece including:
• a first housing having a proximal end and a distal end;
• a second housing proximate the proximal end, wherein the second housing is configured to releasably retain and electrically couple with a battery, the battery configured to deliver up to 1500 volts, and wherein the second housing is removable from the first housing;
• a capacitor in communication with the battery and distal to the second housing;
• an h-bridge in communication with the battery and the capacitor;
• a treatment delivery element configured to releasably couple to the distal end of the first housing, the treatment delivery element being configured to communicate with the battery, the capacitor, and the h-bridge, and deliver biphasic pulsed field ablation to electroporate target tissue using energy from the battery via the capacitor and the h-bridge;
• and
• an inductive charging element configured to charge the battery when in proximity to the battery.
