Abstract: An ablation device for ablating tissue having an outer wall and an inner wall, approximately parallel and concentric with said outer wall, defining an inner fluid chamber and an outer low pressure chamber. Each of the outer wall and the inner wall have an edge defining an open face of the fluid chamber and the low pressure chamber. An ablative element is contained within the fluid chamber. A source of low pressure is coupled to the low pressure chamber. When the edge of the outer wall and the edge of the inner wall contact a surface, the ablation device is at least partially secured to the surface by low pressure created in the low pressure chamber by the source of low pressure. The fluid chamber is at least partially fluidly isolated from the low pressure chamber when the ablation device is at least partially secured to the surface.

Abstract: Embodiments of the invention provide an ablation apparatus for ablating target tissue adjacent pulmonary veins of a patient. The ablation apparatus can include a tube capable of being advanced around the pulmonary veins to form a loop. The tube can receive or include electrodes to ablate target tissue. Some embodiments provide a loop ablation device, which may include a cannula and two or more electrode rods carrying two or more bipolar electrodes. The electrode rods can be advanced through the distal ends toward the proximal ends of the loop and toward the target tissue. The bipolar electrodes can receive energy to ablate the target tissue. The bipolar electrodes may be surrounded by the liquid within the cannula while ablating the target tissue. The loop ablation device can further include a rotating grasping mechanism coupled to the electrode rods.
