SYSTEM AND METHOD FOR DELIVERING ENERGY TO TISSUE
First Claim
1. An ablation device for treating atrial fibrillation in a patient, said device comprising:
- a housing having a proximal end and a distal end; and
an energy source adjacent the distal end of the housing, the energy source having an active portion and an inactive portion,wherein the active portion is adapted to deliver energy to tissue when the energy source is energized thereby creating a partial or complete zone of ablation in the tissue that blocks abnormal electrical activity therethrough, reducing or eliminating atrial fibrillation in the patient, andwherein the inactive portion does not emit energy or emits substantially no energy when the energy source is energized.

Abstract
Methods and apparatus for treating a patient include an ablation device for treating atrial fibrillation. The device includes a housing having proximal and distal ends, and an energy source adjacent the distal end of the housing. The energy source has an active portion and an inactive portion. The active portion is adapted to deliver energy to tissue when the energy source is energized. This creates a partial or complete zone of ablation in the tissue that blocks abnormal electrical activity, thereby reducing or eliminating atrial fibrillation in the patient. The inactive portion does not emit energy or emits substantially no energy when the energy source is energized.

30. A method of ablating tissue in a patient as a treatment for atrial fibrillation, said method comprising:
-
providing a housing having a proximal end, a distal end, and an energy source adjacent the distal end; energizing the energy source so that the energy source delivers energy to the tissue, wherein the energy source comprises an active portion and an inactive portion, and wherein the active portion delivers the energy when the energy source is energized, and wherein the inactive portion does not emit energy or emits substantially no energy when the energy source is energized; and creating a zone of ablation that blocks abnormal electrical activity in the tissue thereby reducing or eliminating atrial fibrillation in the patient. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58)
