The outer jacket is bonded to the inner liner between the coil turns. The coil turns have a cross-section comprising opposing end portions, and a center portion disposed between the opposing end portions. The center portion has a thickness not exceeding about one-third of a thickness of the end portions for reducing a bending modulus of the coil, and the end portions have a generally curved outer surface. At least a distal end portion of the outer jacket has a durometer between about 70 and 90 on the Shore D scale.
