Abstract

Novel and versatile apparatuses for delivering one or more of thermal ablation and irreversible electroporation therapies to target tissue. In some examples, a device includes at its distal end a plurality of electrodes that can be advanced or retracted to pierce patient tissue, with a variable position and size shaft electrode provided near the distal end of the device to allow manipulation of therapy fields to achieve various tissue destruction field shapes. A number of method of use examples are described as well.
