The HeartPad^® is a versatile system intended for ablation of cardiac tissue from an epicardial (outer surface of the heart) location, while simultaneously protecting adjacent structures from unintentional ablation injury. Designed for minimally invasive ablation, our proprietary technology utilizes potent cryothermal energy coupled with a sophisticated delivery system. The intended result is effective and safe transmural (full-thickness) ablation of broad areas of complex cardiac tissue – and to accomplish this despite the barriers of thick tissue, warm cardiac blood flow and the presence of insulating fat tissue on the outer heart surface.
