ABSTRACT:
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.
