Overview
The elegance of the technology is in its simplicity. The device design solves the critical requirement for creation of complete, non conductive lesions in order to interrupt the erratic electrical signals that cause atrial fibrillation.

The Numeris® and EPi-Sense™ Coagulation System with VisiTrax® epicardial ablation devices will transform the arrhythmia market through the advancement of less invasive, and potentially more efficacious ablation alternatives. In order to achieve this, two other treatment limitations needed addressing:
|
In order to create complete lesions, an ablation device must remain in constant contact with the cardiac tissue in order to deliver consistent energy over the lesion. Maintaining uniform tissue contact is a problem and challenge for most ablation devices, including catheters, and why consistent and positive outcomes are limited over time. That is why nContact engineered proprietary suction capabilities in all of its ablation system devices to ensure consistent and predictable contact with cardiac tissue during the creation of linear lesions.
The surgical Maze pattern has proven efficacy but the procedure's invasiveness precludes adoption. By addressing these limitations, the nContact technology has enabled physicians to develop new less invasive procedures. The nContact ablation devices integrate suction, perfusion, and RF energy and are specifically designed for minimally invasive applications.

Gently draws the uneven surface of cardiac tissue into consistent contact with the radiofrequency energy source Provides both audible and visual confirmation of tissue contact |
Perfusion through a dedicated lumen acts to cool the external surface of the device to prevent collateral tissue damage Directs the energy deep into the tissue to prevent charring and create consistent lesions |
Radiofrequency energy is the most common and well-known of energy sources Energy applied epicardially is absorbed by circulating blood flow in the atrium, which acts as a natural heat sink |

It is the integration, not the combination, of these three critical components that forms the basis for the Company’s proprietary technology platform. All three components integrated together ensures consistent tissue contact and complete, visible lesions. nContact’s development advances can be attributed to studying the experience and the limitations of past technologies.
