A liner may be disposed within the lumen and along the inner surface. At least a portion of the liner may be radially spaced from the inner surface of the catheter shaft so that a space is defined therebetween. The liner may include an inner layer, an outer layer, and a polymeric reinforcing member. At least a portion of the polymeric reinforcing member may be disposed between an outer surface of the inner layer and an outer surface of the outer layer.
