摘要： 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.

摘要： 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.

摘要： An improved tissue engagement device such as a suction stabilizer or retractor is provided withone or more suction pods (22) mounted to the distal end of a flexible arm (20). The flexible arm is coupled to abase assembly (24) that includes a fixed portion, which is coupled to a rotatable turret, allowing rotation of the arm relative to the fixed portion of the base assembly. A tensioning mechanism mounted to the turret applies tension to rotationally lock the turret and to lock the arm in its current configuration. If the device is a suction stabilizer, it may carry a spreading/tightening mechanism (21) along with two suction pods (22) and the tensioning mechanism may lock the relative location of the spreading/tightening mechanism relative to the arm. If the device is a suction retractor, the tensioning mechanism may lock a pivotably mounted carrier for a single enlarged suction pod so that the suction pod is held in its desired orientation relative to the arm.

摘要： Methods and apparatus employed in surgery involving making precise incisions through body vessel walls, particularly coronary arteries. A body vessel cutting instrument comprises an elongated instrument shaft extending between a shaft proximal end adapted to be manipulated outside the patient's body and a shaft distal end and having a shaft axis and first and second cutting blades supported at the shaft distal end. The first cutting blade extends substantially orthogonally or laterally to the shaft axis and has a first cutting edge extending along a trailing side, a cutting tip at the first cutting blade free end, and an atraumatic blunt surface along the leading side. The second cutting blade has a second cutting edge extending along a leading side, whereby the first and second cutting edges face one another and are brought together to slit a vessel wall.
