Development of a Radiofrequency Ablation Device with Simultaneous Determination of the Transmural Effect Achievement

The aim of the study is to develop a radiofrequency ablation device with simultaneous determination of the transmural effect achievement. In this case, the device should provide high-quality heating of the inner layers of tissue and determine the effect of achieving transmurality in a shorter time compared to analogs. The structure of the hardware part of the radiofrequency ablation device with the simultaneous determination of the achievement of the transmural effect is proposed. An algorithm for the functioning of the system to determine the achievement of the transmurality effect, capable of controlling additional parameters, has been developed. In particular, the control and regulation of the heating rate of the tissue is carried out, the volume of the processed tissue is estimated, the required amount of energy to heat a certain volume of tissue is calculated, and the correspondence of the actually consumed amount of energy to the calculated one is monitored. It can significantly improve the uniformity of myocardial damage in its different layers.
