1. An apparatus comprisinga fluid-tight tube with a substantially round cross section;

  • a helical support structure disposed outside the tube, the helical support structure having (a) an inner surface that is bonded to the tube and (b) an outer surface; and

    an elastomeric material disposed on the tube and on the outer surface of the helical support structure, the elastomeric material having an outer surface with a substantially round cross section, so that portions of the elastomeric material disposed on the helical support structure are thinner than portions of the elastomeric material disposed directly on the tube, resulting in a groove in the elastomeric material that facilitates preferential tearing of the elastomeric material at the groove.
