The Cardioblate Surgical Ablation System is cleared in Canada and Europe for ablation of cardiac tissue for the treatment of cardiac arrhythmias. In the United States, the Cardioblate bipolar is approved for soft tissue ablation, while the Cardioblate Pen is approved for cardiac tissue ablation. The purpose of the clinical study is to obtain a labeling claim for the US market that the Cardioblate Surgical Ablation System can be used for ablation of cardiac tissue in the treatment of cardiac arrhythmias such as atrial fibrillation among permanent and persistent AF patients.
A prospective, non-randomized, multi-center clinical trial. The patient population includes patients with permanent or persistent AF requiring valve replacements or repairs, ASD repairs, PFO closure or coronary artery bypass grafts (CABG) procedures. Patients are not allowed to have had previous atrial ablation, AV-nodal ablation, or surgical Maze procedure.
