ABSTRACT:
A composite ventilation tube is disclosed which is specifically useful for ventilating the middle ear. The tube assembly includes an outer tube formed of inert, slightly flexible material, such as Teflon or polyethylene, which includes an elongated thin-walled tubular section having a central bore and a plurality of axially spaced, angularly staggered transverse openings. A flange is formed at one end of the tube, the plane of the flange being disposed at an acute angle relative to the axis of the tube with at least one portion of the flange terminating closely adjacent to the tubular wall. A cylindrical piston fits within the tube and includes a slightly enlarged head engaging the open, outer end of the tube. The piston is formed of porous polyethylene having pores of the order of 20 to 50 microns.
