Abstract
A prosthesis for replacing part or all of the ossicles of the ossicular chain in the tympanic cavity. The prosthesis includes a porous body having an enlarged head for being closely associated with the tympanic membrane and having an elongated shaft for being coupled to the fenestra vestibuli. A metal core is encased within the body for collecting sound vibrations from the tympanic membrane and for transmitting the collected sound vibrations to the fenestra vestibuli. The metal core has substantially higher sound vibration and collecting qualities than the porous body.
