The deflectable intermediate section includes at least two elongated bias members that extend along the length and lie on a plane perpendicular to the plane of deflection so as to resist flexure outside of the plane of deflection. In a more detailed embodiment, the deflectable intermediate section has an integrated tubular 10 construction that includes an inner layer, a braided mesh surrounding the inner layer and an outer layer, where the bias members can be situated between the inner layer and the braided mesh, or between the braided mesh and the outer layer. 09/09/10.va 18836 speci.doc.201/10 0 CNN NI I I
