Claim:
1. A device comprising: an elongate body, wherein the elongate body has a longitudinal axis; a variable length tip portion at a distal end of the elongate body, wherein the variable length tip portion comprises a first elastically deformable electroformed pleated region and the elongate body comprises a second elastically deformable electroformed pleated region, wherein the first and second elastically deformable electroformed pleated regions comprise adjacent pleats that extend perpendicularly to the longitudinal axis, such that the first and second elastically deformable electroformed pleated regions expand axially, and further wherein the first and second elastically deformable electroformed pleated regions are capable of being extended to a length that is greater than the undisturbed length; and at least one lumen; wherein the first elastically deformable electroformed pleated region further comprises at least one ablation element, and wherein the first elastically deformable electroformed pleated region in the variable length tip portion is more flexible than the second elastically deformable electroformed pleated region in the elongate body.
