Abstract
A prosthetic device formed of a biodegradable material and useful as a ventilation tube for insertion between the middle ear and the outer ear. The device includes a shaft with an axial passage, an inner flange and an outer flange. At least a portion of the outer surface of the shaft is tapered, with the taper increasing from the inner to the outer flange. The larger diameter outer flange and any attached portion of the shaft are, therefore, forced outwardly when the tapered portion of the shaft is in contact with animal tissue biodegrades before other portions of the prosthesis.
