Primary Outcome Measures:
  • AF free, off all Class I and III Anti Arrhythmic Drugs (AADs) [ Time Frame: 12 months ]
    The primary efficacy data will be an evaluation of the number of subjects free from AF and free of all Class I and III Anti Arrhythmic Drugs (AADs) from 3 months through 12 months post procedure.


Secondary Outcome Measures:
  • AF free regardless of the Class I and III AADs status [ Time Frame: 12 months ]
    The secondary efficacy data will be an assessment of the number of subjects free from AF regardless of their Class I and III AADs status from 3 months through 12 months post procedure.


Enrollment: 7
Study Start Date: April 2010
Study Completion Date: April 2013
Primary Completion Date: October 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Numeris-AF Guided Coagulation System Device: Numeris®-AF Guided Coagulation System with VisiTrax®
Combined epicardial / endocardial procedure using the nContact Numeris®-AF Guided Coagulation System with VisiTrax® epicardially and the St. Jude Medical Therapy™ Cool Path™ Ablation Catheter endocardially.

Detailed Description:
The purpose of this feasibility study is to evaluate the safety and efficacy of the epicardial / endocardial combined procedure using the nContact Numeris®-AF Guided Coagulation System with VisiTrax® epicardially and the St. Jude Medical Therapy™ Cool Path™ Ablation Catheter endocardially to treat longstanding persistent Atrial Fibrillation (AF) patients.
