A system forms a cardiac conduction block at a location in a heart of a patient without substantially ablating cardiac tissue. The system includes a delivery system coupled to a source of material that is substantially non-ablative with respect to cardiac tissue. The delivery system delivers the material to the location, and the material at the location forms a conduction block without ablating the cardiac cells there.
