CONVERGE CAP Study-For The Treatment Of Symptomatic Persistent or Long-standing Persistent AF

The epicardial lesion pattern will be created using the EPi-Sense®-AF Guided Coagulation System with VisiTrax®. Epicardial linear lesions will be created endoscopically using the EPi-Sense-AF Guided Coagulation System with VisiTrax throughout the posterior left atrium and along the pericardial reflections from a trans-diaphragmatic or sub-xyphoid access without any chest incisions. An endocardial ablation catheter will be used to ablate endocardially to connect lesions at the reflections, complete the isolation of the pulmonary veins and create a cavotricuspid lesion to prevent typical atrial flutter. Once the study lesion pattern has been created by coagulating cardiac tissue using the EPi- Sense-AF Guided Coagulation System and the endocardial ablation catheter, the pulmonary veins must be evaluated for entrance and/or exit block to confirm isolation.
