Patent number: 7658764Abstract: 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.Type: GrantFiled: August 4, 2006Date of Patent: February 9, 2010Assignee: Clarity CorporationInventors: Harlan J. Reitan, Michael D. White

Patent number: 7288113Abstract: 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.Type: GrantFiled: October 29, 2004Date of Patent: October 30, 2007Assignee: Clarity CorporationInventors: Harlan J.

Patent number: 6942696Abstract: An ossicular prosthesis delivery system having an ossicular prosthesis including an enlarged head and a shaft axially, moveably mounted to the head to adjust shaft length. An elongate main body having an operating portion, including a cylindrical through bore, connected to an adjusting portion, including a generally semi-cylindrical upwardly opening channel coaxial with the bore. An end wall at a distal end of the adjusting portion includes a through passage coaxial with the channel and an upwardly opening cavity. An elongate cylindrical plunger has a claw at one end. The plunger is received in the bore with the claw in the channel and an opposite end extending outwardly of the operating portion. The ossicular prosthesis' shaft is positioned in the channel with the head received in the cavity and the plunger is rotatable in the bore to capture the shaft and is reciprocally moveable in the bore to adjust shaft length of the ossicular prosthesis.Type: GrantFiled: April 28, 2004Date of Patent: September 13, 2005Assignee: Clarity CorporationInventors: Michael D. White, Anthony D. Prescott, Harlan J. Reitan

Patent number: 5163957Abstract: A prosthesis for use with an intact ossicular chain to allow a magnet to be coupled to the ossicular chain, the magnet being moved by an electromagnetic induction hearing aid. The prosthesis has a body having a first groove which cooperates with the manubrium and a second groove formed by an arm extending from the body and a hooked end, the second groove cooperating with the long process. A magnet is connected to a planar surface developed by the arm and the hooked end and is generally parallel to the tympanic membrane when installed. A conventional disk shaped magnet can be utilized inside a biocompatible housing.Type: GrantFiled: September 10, 1991Date of Patent: November 17, 1992Assignee: Smith & Nephew Richards, Inc.Inventors: Yacov Sade, T.
