Abstract
A system for ablation is described herein including an inner electrode assembly with an inner elongate shaft and a distal electrode, an outer electrode assembly having an outer elongate shaft and a proximal electrode, wherein the outer electrode assembly defines a central passage configured to slidably receive the inner electrode assembly, wherein the distal electrode or the proximal electrode is axially moveable with respect to the other, and an energy source configured to be electrically connected to the distal electrode and the proximal electrode and configured to deliver a pulsed electric field (PEF). One of the distal electrode and proximal electrode is part of a first expandable electrode array comprising two or more electrode elements moveable between an unexpanded position and an expanded position.
