This allows surgeons direct visualization while ablating on the posterior of the heart. nContact is the first ablation company that allows direct access to the posterior of the atrium without handling the heart. Creating long, linear, epicardial lesions on the posterior eliminates the need for EPs to do extensive endocardial ablation on the posterior. By accessing the heart through the diaphragm, the need for chest incisions is eliminated. This SUBTLE™ access created by the physician using the cannula enables a truly closed chest endoscopic approach.
