[The development of a RF electrical pole catheter for heart ablation]
Abstract:
This article describes a RF electrical pole catheter for heart ablation. There is a device in the catheter, that can adjust the bending of the catheter tip on which there are a pair of electrical poles that is able to record and map the electrical potential of the heart, and to transfer 50 W electrical energy for focus ablution of heart disease.
