Patent ID: 8915911

Claim:
A system for non-thermal tissue ablation, comprising: a tissue treatment probe having one or more elongate electrodes shaped for positioning or advancement within a target tissue region comprising cancerous cells; and an energy source coupled to the probe and configured to cause the probe to apply an alternating electrical field of less than 50 V/cm to the target tissue region to non-thermally destroy cancerous cells of the target tissue region; and a control system operatively connected to the energy source and the probe, the control system comprising: one or more processors; and memory, including instructions stored thereon that, when executed by the one or more processors, cause the control system to at least provide, via the one or more elongate electrodes when positioned in target tissue, the alternating electrical field through the target tissue region so as to non-thermally destroy the cancerous cells of the target tissue region around the electrodes, the electrical field comprising a frequency between about 50 kHz to about 300 kHz.
