Patent ID: 8465479

Claim:
A method of coagulating tissue to create a bi-atrial coagulation pattern on a first and a second atrial surfaces where the first atrial surface and the second atrial surface are located on opposite sides of the cardiac tissue, the method comprising: positioning a first coagulation device adjacent to the first atrial surface of the cardiac tissue; creating a first partial coagulation pattern on the first atrial surface with the first coagulation device, where the first partial coagulation pattern comprises at least a first plurality of lesions where at least two of the first plurality of lesions are separated by a gap section, where the gap section allows an electrical impulse to flow therethrough in the cardiac tissue; positioning a second coagulation device adjacent to the second atrial surface of the cardiac tissue; and creating a second partial coagulation pattern on second surface with the second coagulation device, where the second partial coagulation pattern comprises at least one lesion across the gap to form the complete coagulation pattern such that the electrical impulse cannot flow across the complete coagulation pattern.
