RADIO-FREQUENCY BASED CATHETER SYSTEM FOR ABLATION OF BODY TISSUES
摘要
A method of ablating body tissue using a catheter which has an ablating element to deliver radio-frequency frequency energy to body tissue and an electrical hollow cable to conduct radio-frequency energy between a radio-frequency energy source and the ablating element. The electrical hollow cable used has first and second coaxial elongate electrically conductive tubular members coupled to the ablating element. A tubular dielectric member is disposed between the first and second tubular members without an air gap therebetween. There is an axial lumen through which the deployable guide is slidably received. In the method, the ablating member is deployed out of the catheter by eliding the electrical hollow cable over the deployable guide; and the body tissue is ablated with the ablating element.
