Ablation Systems

Medtronic's DiamondTemp Ablation (DTA) system is FDA cleared to treat patients with recurrent, symptomatic paroxysmal atrial fibrillation (AF) and who have been unresponsive to drug therapy. The DiamondTemp system is the first FDA-approved, temperature-controlled, irrigated radiofrequency (RF) ablation system with diamonds currently available to deliver ablations.

Attune Medical’s ensoETM is a single use thermal regulating device that is placed in the esophagus similar to a standard gastric tube and connected to an external heat exchange unit, creating a closed-loop system for heat transfer to increase or decrease patient temperature. EPs are now looking at the device as a way to prevent RF damage to the esophagus during cardiac ablations.
 

The study used cadaver hearts that were images with contrast enhanced MRI and the images used to create a 3-D computation model of the electrical activation in the heart and how it was influenced by adenosine and ablation. Find more images in the original article
