Abstract
An improved forming wire is described. A forming wire in a first embodiment comprises a base comprising a structure with a bore therethrough, a first support arm and a second support arm, each said arm projecting normally from said base, each said arm having a proximal tip connected to said base and a distal tip remote from said base, a bending loop having an arcuate shape and extending from the distal tip of the first support arm to the distal tip of the second support arm, an inner arm having a helical shape and extending from the distal tip of the first support arm to the base; and an outer arm having a helical shape and extending from the distal tip of the second support arm to a point above the base, thereby defining a space between the base and the outer arm. In other embodiments, the forming wire has a single support arm. In some embodiments, the forming wire is made of poly-tetrafluoroethylene tubing over stainless steel rods.
