METHOD AND SYSTEM FOR POSITIONING AN ENERGY SOURCE
First Claim
1. An ablation system for treating atrial fibrillation in a patient, said system comprising:
- an elongate inner shaft having a proximal end, a distal end and a lumen therebetween;
a distal tip assembly adjacent the distal end of the inner shaft, the distal tip assembly comprising an energy source and a sensor, wherein the energy source is adapted to deliver energy to a target tissue so as to create a zone of ablation in the target tissue that blocks abnormal electrical activity thereby reducing or eliminating the atrial fibrillation in the patient; and
an elongate outer shaft having a proximal end, a distal end and a lumen therebetween,wherein the inner shaft is slidably disposed in the outer shaft lumen, and wherein the inner shaft is rotatable, bendable and linearly slidable relative to the outer shaft, and wherein the outer shaft is rotatable, bendable and linearly slidable relative to the target tissue.

Abstract
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.

44. A method for treating atrial fibrillation in a patient by ablating tissue, said method comprising:
-
providing an ablation system comprising an outer shaft and an inner shaft having a distal tip assembly, the distal tip assembly comprising an energy source and a sensor, wherein the outer shaft is slidably disposed over at least a portion of the inner shaft; positioning the distal tip assembly adjacent the tissue; manipulating the inner shaft or the outer shaft so as to place the energy source in a desired position relative to the tissue; delivering energy from the energy source to the tissue; and creating a partial or complete zone of ablation in the tissue thereby blocking abnormal electrical activity and reducing or eliminating the atrial fibrillation. - View Dependent Claims (45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85)
