Abstract: A middle ear prosthesis comprises a body of deformable material capable of retaining different shapes. The body comprises a slotted wall defining a cavity for receiving a bone of the middle ear. The wall is deformable proximate slots in the wall between an open position for receiving the bone and a closed position wherein the body is reshaped to grasp the bone.

Abstract: A middle ear prosthesis comprises a member adapted to supplement an ossicular bone when implanted in an ear. An anatomically conforming structure is secured to the member comprising an upper arcuate portion and a lower arcuate portion, each having near and distal ends. A crimp assist portion is connected to the near ends of the upper and lower arcuate portions so that the upper and lower arcuate portions generally define portions of a circle for partially surrounding a bone. The crimp assist portion extends outside of the circle. The crimp assist portion is of a crimpable metal capable of retaining different shapes so that the crimp assist portion can be crimped to close the structure around the bone without crimping within the circle.

Abstract: A middle ear prosthesis comprises a one piece disk shaped prosthesis including a generally circular malleable body including a bore. The body engages a tympanic membrane and the bore receives a head of a stapes when implanted in a middle ear. More particularly, the middle ear prosthesis comprises a body comprising an annular head, a collar, and a plurality of radially extending members connecting the head to the collar. The head engages a tympanic membrane and the collar receives a head of a stapes when implanted in a middle ear.

Abstract: A titanium incudo-stapedial joint prosthesis comprises a body including a generally tubular wall defining a first cavity for receiving a head of a stapes. A generally U-shaped wall is connected to the tubular wall defining a second cavity extending generally perpendicular to the first cavity for receiving an incus. The tubular wall comprises slots to enable the first cavity to be sized to fit the head of the stapes. The general U-shaped wall comprises slots to enable the second cavity to be sized to fit to the incus.
