nContact Initiates US Clinical Trials for the Treatment of Atrial Fibrillation

Why Address Atrial Fibrillation (AF)?
Atrial Fibrillation (AF) is a type of arrhythmia. AF is characterized by very fast, irregular beating of the heart's upper chambers (the atria). AF increases the risk of stroke by fivefold¹, and can lead to the progression of heart disease. Learn more >>

Open Chest Trial
nContact Inc. is conducting this trial to evaluate the safety and efficacy of the treatment of longstanding persistent AF using the investigational Numeris^® - AF Tethered Coagulation System with VisiTrax^® in patients scheduled for open heart surgery.  Learn more >>

Closed Chest Trials
nContact Inc. is evaluating the safety and efficacy of a combined epicardial (outer surface of heart tissue) /endocardial (inner surface of the heart tissue) beating heart ablation procedure without chest incisions or ports:

• For the treatment of symptomatic paroxysmal atrial fibrillation using the investigational Numeris^® - AF Guided Coagulation System with VisiTrax^® and the Biosense Webster^® ThermoCool^® Ablation Catheter
• For the treatment of longstanding persistent atrial fibrillation using the investigational Numeris^® - AF Guided coagulation System with VisiTrax^® and the St. Jude Medical Therapy^® Cool Path^® Ablation Catheter.
