The Numeris® Coagulation System with VisiTrax® epicardial ablation device will transform the cardiac ablation market through the advancement of less invasive, and potentially more efficacious ablation alternatives. In order to achieve this, two other ablation limitations needed addressing:

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 erratic electrical signals.
In order to create complete lesions, an ablation device must remain in constant contact with cardiac tissue in order to deliver consistent energy along the lesion. Maintaining uniform tissue contact is a problem and challenge for most ablation devices, including catheters, and why reported consistent and positive patient 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.

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 complete 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.
