摘要：
An ablation system for treating atrial fibrillation in a patient comprises an inner shaft having proximal and distal ends as well as a lumen therebetween. A distal tip assembly is adjacent the inner shaft distal end, and the distal tip assembly comprises an energy source and a sensor. The energy source is adapted to deliver energy to a target tissue so as to create a zone of ablation in the target tissue. This blocks abnormal electrical activity and thus reduces or eliminates atrial fibrillation in the patient. The system also has an outer shaft with proximal and distal ends, and a lumen therebetween. The inner shaft is slidably disposed in the outer shaft lumen, and the inner shaft is rotatable, bendable and linearly slidable relative to the outer shaft. The outer shaft is rotatable, bendable and linearly slidable relative to the target tissue.
