Original Abstract Submitted
An electroporation catheter for ablation of cardiac tissue is disclosed. The electroporation catheter includes an elongated shaft having a proximal end and an opposite distal end. The elongated shaft defines an axis. An electrode assembly is coupled to and extends distally from the distal end of the elongated shaft. The electrode assembly is transitionable between a collapsed state and an expanded state. The electrode assembly includes conductive struts that define a spherical shape in the expanded state having a proximal portion coupled to the elongated shaft, a central portion having a maximum radial dimension and a distal portion opposite the elongated shaft. A proximal insulation portion is disposed on the proximal portion of the electrode assembly surrounding each of the plurality of conductive struts. The proximal insulator portion extends from the proximal end to at least the central portion.
