The HeArTPAD™ device is not for sale in the United States. It is delivered and positioned adjacent to the heart using video guidance for minimally invasive ablation procedures and is intended to ablate generally large contiguous areas of cardiac tissue, such as atrial tissue, with each individual application. Once in position the device is expanded by inflating its insulation chamber. This causes the unique ablating surface to come into contact with an external (epicardial) surface of the heart that is targeted for ablation. Integrated sensors provide data to help direct ablation therapy.  Once an appropriate target is identified ultra-cold Argon gas is channeled through the ablating surface attaching the ablation pad to the contacted heart by a process called cryoadhesion.  The contacted surface of the heart is ablated while adjacent areas are protected from ablation injury by the insulation chamber. Standard catheter ablation (i.e. pulmonary vein ablation) can be performed simultaneously using commercially available devices. After ablation is completed Helium gas is supplied to thaw the ablation pad which reverses the cryoadhesion and allows re-positioning of the device if additional ablation is required. Once the desired degree of ablation is completed the HeArTPAD™ device is collapsed and withdrawn from the pericardial cavity.

About Ablation

Ablation is a general methodology to destroy or disable abnormal tissue in the body that is causing disease or dysfunction. Ablation therapies have been used to destroy cancerous tumors and to disrupt electrical energy that causes heart rhythm disturbances. Many energy sources can be used for ablation, including extreme heat, microwave, ultrasound, laser, and cryothermy (freezing).
