1. A clamping ablation tool for ablating target tissue adjacent pulmonary veins of a patient, the clamping ablation tool comprising:

  • an upper arm including an upper neck, a link assembly, and an upper actuator, the link assembly including a distal electrode and a proximal electrode, the link assembly capable of being guided around the pulmonary veins, the upper actuator controlling movement of the link assembly; and

    a lower arm that mates with the upper arm, the lower arm including a lower neck, a distal jaw, and a lower actuator, the distal jaw including a jaw electrode, the lower actuator controlling movement of the distal jaw;

    the upper actuator and the lower actuator being independently operable in order to position the link assembly and the distal jaw independently;

    the distal electrode and the proximal electrode receiving energy independently of the jaw electrode in order to allow partial blood flow through the pulmonary veins and create a continuous lesion.
