Abstract
Catheter systems, tools and methods are disclosed for the selective and rapid application of DC voltage pulses to drive irreversible electroporation for minimally invasive transurethral prostate ablation. In one embodiment, a switch unit is used to modulate and apply voltage pulses from a cardiac defibrillator, while in another, the system controller can be configured to apply voltages to an independently selected multiplicity or subsets of electrodes. Devices are disclosed for more effective DC voltage application including the infusion of cooled fluid to elevate the irreversible electroporation threshold of urethral wall tissue and to selectively ablate regions of prostate tissue alone.
