Abstract
Devices and methods of use for treating atrial arrhythmias. A single-pass lead includes a body portion having at least two electrodes configured to be positioned within or adjacent a right atrium of a heart of a patient, and a distal portion having at least two electrodes configured to be positioned within a blood vessel proximate the left atrium. The lead is configured to be operated by an implantable therapy generator programmed to deliver a multi-stage therapy by activating 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.

(canceled)
A method, comprising:
- providing a lead configured for implantation in a patient, the lead including:
- a proximal portion configured to be connectable to an implantable therapy generator;
- a body portion having at least two electrodes;
- and
- a distal portion having at least two electrodes;
- and
- implanting the lead in the patient such that the at least two electrodes on the body portion are positioned at a first heart location of the patient, and such that the at least two electrodes on the distal portion are positioned at a second heart location 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 arrhythmia has occurred, the multi-stage therapy including at least a first stage for unpinning of one or more singularities associated with the arrhythmia, a second stage for anti-repinning of the one or more singularities associated with the arrhythmia, and a third stage for extinguishing of the one or more singularities associated with the arrhythmia, wherein each of the stages includes a plurality of pulses.
