1. A method for treating benign prostate hyperplasia (BPH) of a prostate, comprising:
- introducing a bi-polar electrode to a BPH tissue site of a patient;
positioning the bi-polar electrode at or near the BPH tissue site;
using a programmed control circuit to treat the BPH tissue and to control the temperature of the BPH tissue site by applying an electric field to the BPH tissue site in an amount sufficient to produce irreversible electroporation of cells at the BPH tissue site and below an amount that causes thermal damage to a majority of the BPH tissue site.

Abstract
A system for treating benign prostate hyperplasia (BPH) of a prostate. At least first and second mono-polar electrodes are configured to be introduced at or near a BPH tissue site of the prostate gland of the patient. A voltage pulse generator is coupled to the first and second mono-polar electrodes. The voltage pulse generator is configured to apply sufficient electrical pulses between the first and second mono-polar electrodes to induce electroporation of cells in the BPH tissue site, to create necrosis of cells of the BPH tissue site, but insufficient to create a thermal damaging effect to a majority of the BPH tissue site.
