Details and patient eligibility

About

A prospective, single arm, multi-center exploratory study of safety and feasibility in the treatment of patients undergoing cardiothoracic surgery.

Full description

To assess the safety and feasibility of electroporation/Pulsed Electric Field (PEF) as a technology to achieve selective GP ablation. This treatment will be performed on 30 patients undergoing cardiothoracic surgery. Primary feasibility endpoint will be demonstration of ability to access and deliver Pulsed Electric Field energy to all of the targeted ablation sites.
