Zusammenfassung:An apparatus and method of manufacture includes a helical wire coil body having a proximal body end portion and a distal body end portion that extend along a longitudinal coil axis. The apparatus also includes a non-extensible, core wire assembly configured to inhibit longitudinal elongation of the helical wire coil body along the longitudinal coil axis. The core wire assembly has a first core wire and a second core wire respectively extending from the proximal body end portion toward the distal body end portion. The second core wire proximally terminates relative to the first core wire such that the distal body end portion is more flexible than the proximal body end portion. The first and second core wires transversely overlap to provide a collective column strength to the helical wire coil body along the longitudinal coil axis.
