Abstract
This invention relates to an ablation device, comprising a handle; a catheter with a proximal end connected to the handle and a distal end forming a flexible ablation segment suitable for insertion into a patient's body cavity through a body channel, the ablation segment having a first working section and a second working section in a working state; multiple electrodes disposed on the ablation segment; an energy generator for providing ablation energy to the electrodes; and a blocking member disposed on the ablation segment to prevent the two working sections from abutting each other, ensuring that the distance between the electrodes located on the two working sections is greater than a predetermined distance. The blocking member of the ablation device can also be used to increase the electrical clearance between adjacent electrodes. This invention, by providing a blocking member on the ablation segment, can create a certain space around the catheter, preventing adjacent first and second working sections of the catheter's ablation segment from abutting each other, maintaining the shape and structure of the ablation segment, avoiding arcing between electrodes, ensuring smooth operation, and patient safety.
