Abstract
An electrode loop assembly for a catheter includes a form wire shaped as a loop, an activation wire coupled to the form wire, and a support tube defining a lumen and enclosing the form wire and the activation wire therein. The activation wire is operable to selectively vary a diameter of the loop, and is routed along a radial inner side of the form wire. The support tube extends along a longitudinal axis from a proximal end to a distal end, and has an oblong cross-section having a major axis. The support tube is twisted about the longitudinal axis such that an orientation of the major axis changes along a length of the support tube.
