Description

STATEMENT OF RELATED APPLICATION

[0001] This application claims the benefit of priority of U.S. Provisional Patent Application No. 60 / 618,753, filed Oct. 14, 2004, entitled “Ablation Catheter,” which is incorporated by reference herein in its entirety.FIELD OF THE INVENTION

[0002] The present invention relates generally to catheters and methods for performing targeted tissue ablation in a subject. In particular, the present invention provides devices comprising catheters having distal ends configured to treat two dimensional regions of target tissue, including deployable distal ends, and methods for treating conditions (e.g., cardiac arrhythmias) with these and similar devices. BACKGROUND OF THE INVENTION

[0003] Tissue ablation is used in numerous medical procedures to treat a patient. Ablation can be performed to remove undesired tissue such as cancer cells. Ablation procedures may also involve the modification of the tissue without removal, such as to stop electrical propagation t...
