Hydrogel Heart Model Having Temperature Indicating Function

We developed a hydrogel heart model having temperature indicating function for evaluating surgical skills of the catheter ablation. Left atrium model was fabricated using hydrogel material to elaborate human heart properties such as mechanical, thermal, and electrical properties. Irreversible temperature indicator was impregnated into the heart model to detect the temperature increase on the heart model by color change. We demonstrated color change of the fabricated left atrium model by heating the model.
