Claim 7:
8. A method, comprising:
providing a single-pass lead configured for implantation in a patient, the lead including:
a proximal portion configured to be connectable to the implantable therapy generator;
a body portion having at least two electrodes; and
a distal portion having at least two electrodes; and

providing instructions, the instructions comprising:
implanting the single-pass lead in the patient such that the at least two electrodes on the body portion are positioned within or adjacent a right atrium of a heart of a patient, and such that the at least two electrodes on the distal portion are positioned within a blood vessel proximate the left atrium, and further such that no electrodes are within a right ventricle of a heart of the patient; and

causing the implantable therapy generator to deliver a multi-stage therapy according to a program, wherein various combinations of at least one electrode of the body portion of the lead and at least one electrode of the distal portion of the lead are activated in response to an indication an atrial arrhythmia has occurred, the multi-stage therapy including at least a first stage for unpinning of one or more singularities associated with the atrial arrhythmia, a second stage for anti-repinning of the one or more singularities associated with the atrial arrhythmia, and a third stage for extinguishing of the one or more singularities associated with the atrial arrhythmia.
