Flexible ablation tube and ablation method using the same

Abstract

The flexible ablation tube includes a flexible ablation element, a power cord, and a cooling tube. The flexible ablation element has a current-limiting space. The power cord is electrically connected to the flexible ablation element. The cooling tube connects to the current-limiting space and provides cooling fluid.

Claims
