摘要：A tissue ablation device creates long linear lesions along a body space wall ofan animal, and primarily between adjacent pulmonary vein ostia in a left atrial wall. Anablation element includes first and second ends that are bordered by first and secondanchors. The anchors are adapted to secure the ablation element ends at predetermined
first and second locations along the body space wall such that the ablation element isadapted to ablate an elongate region of tissue between those locations. The anchorsmay be guidewire tracking members, each including a bore adapted to receive and trackover a guidewire, and may anchor within adjacent pulmonary vein ostia when the engagedguidewires are positioned within the respective veins. Stop members may be provided onthe guidewires and may be adapted for positioning the relative anchors or for forcing theanchors to fit snugly within the vein ostia. A conduit passageway through the catheterhouses a stiffening stylet which may be advanced into the region of the ablation elementin order to impart a shape to that element to conform it to a predetermined region ofanatomy, or to stiffen the underlying catheter in order to advance the assembly intoremote anatomy.
