Numeris-AF Tethered Coagulation System With VisiTrax Indicated For Treatment of Persistent and Longstanding Persistent Atrial Fibrillation

This is a multi center, non-randomized, prospective, open label, clinical trial evaluating
the safety and efficacy of the nContact Surgical Numeris-AF Tethered Coagulation System when
used to treat patients with persistent and longstanding persistent AF during concomitant
cardiac surgery.

The purpose of this study is to determine the safety and efficacy of the Numeris-AF Tethered
Coagulation System with VisiTrax when used to treat persistent and longstanding persistent
Atrial Fibrillation(AF)during concomitant cardiac surgery.
