    applying force against the submucosal tissue with the convex shape of the tissue-contact surface to at least temporarily deform the submucosal tissue;

    delivering an energy based therapy to the submucosal tissue through the treatment element, by delivering radiofrequency energy between the two rows of electrode pairs, to at least one of reshape, remodel, strengthen or change a property of the submucosal tissue; and
