                an elongate member distal a hub portion and forming a lumen extending to a distal end of the elongate member, the elongate member comprising: 
              a plurality of elastic portions forming a surface of the lumen, wherein deformation of the plurality of elastic portions changes a shape of the surface of the lumen and an outer surface of the elongate member; and 
                  a plurality of sheath portions that are stiffer than the plurality of elastic portions, the plurality of elastic portions and the plurality of sheath portions being disposed in alternating fashion circumferentially around the elongate member, 
                  wherein the plurality of elastic portions and the plurality of sheath portions extend into a distal end of the hub portion.
