Abstract: Method and apparatus for ablating target tissue adjacent pulmonary veins of a patient. A clamping ablation tool can include an upper arm (12) having an upper neck (24), a link assembly (25), and an upper actuator (18). The link assembly can include a distal electrode and a proximal electrode. The clamping ablation tool includes a lower arm (14) that mates with the upper arm (12). The lower arm (21) can include a lower neck (42), a distal jaw (44), and a lower actuator (46). The distal jaw can include a jaw electrode (48), and the lower actuator (46) can control movement of the distal jaw (44).
