Abstract
Catheter systems and methods for the selective and rapid application of DC voltage to drive irreversible electroporation are disclosed herein. In some embodiments, an apparatus includes a voltage pulse generator and an electrode controller. The voltage pulse generator is configured to produce a pulsed voltage waveform. The electrode controller is configured to be operably coupled to the voltage pulse generator and a medical device including a series of electrodes. The electrode controller includes a selection module and a pulse delivery module. The selection module is configured to select a subset of electrodes from the series of electrodes. The selection module is configured identify at least one electrode as an anode and at least one electrode as a cathode. The pulse delivery module is configured to deliver an output signal associated with the pulsed voltage waveform to the subset of electrodes.
