1. A method of forming a lesion in body tissue, comprising the steps of:
- positioning a first probe including a first probe body defining a proximal portion and a distal portion, a loop structure associated with the distal portion, and at least one operative element associated with the loop structure such that the loop structure is at least adjacent the tissue;
positioning a second probe including a second pmbe body defining a proximal portion and a distal portion and an expandable push structure associated with the distal portion such that the expandable push structure is adjacent the loop structure; and
urging the loop structure in the direction of the tissue with the expandable push structure.

Abstract
An apparatus that facilitates the creation of circumferential lesions in body tissue. The apparatus includes a first probe having a loop structure that supports electrodes or other operative elements against the body tissue and a second probe with an expandable push structure that may be used to urge the loop structure against body tissue.
