Jan 8, 2002

Appl. No.:

10/041324

Inventors:

Patrick Antonelli - Gainesville FL 32610-0264
Anthony D. Prescott - Bartlett TN 38133

International Classification:

A61F 218

US Classification:

623 10, 623 11, 600 25, 607 55, 607137

Abstract:

A middle ear prosthesis comprises a piston adapted to extend through an oval window when implanted in a human ear. A pair of jaws engage an ossicle when implanted in a human ear. A spring is coupled to the jaws for biasing the jaws toward one another to provide clamping pressure. The jaws are in turn connected to the piston.

Assignee:

Clarity Corporation - Memphis TN

International Classification:

A61F002/18

US Classification:

623 10

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.

Clarity Corporation - Memphis TN

International Classification:

A61F 2/18

US Classification:

623 10

Abstract:

A stapedial prosthesis includes a body defining a bucket and a shaft, and a bail handle coupled to the bucket. The bucket is preferably adjustable in diameter to fit the incus lenticular process. The shaft preferably has a varying diameter, with a central portion of a smaller diameter than a distal portion which aids in depth perception during implantation and reduces mass to permit better sound energy transmission by the prosthesis. The bail handle is preferably spring-loaded and preferably constructed of titanium. The bail handle is preferably coupled to the body without crimping, twisting or welding and preferably biases the incus toward the bucket. A method of implanting a stapedial prosthesis is also provided.

Abstract:

A lacrimal insert includes a body defining a reservoir, and a head provided at an end of the body and closing the reservoir. The body is made from a material impermeable to the medication while the head is made from a permeable material adapted to release the medication from the reservoir to the eye at a determinable rate. In one manufacture, the body of the insert is molded and includes a hole at a tip end; the head is molded onto the body; the medication is injected into the insert through the tip end hole; and the tip end is sealed. The portion of the insert at which the medication is released is precisely fabricated in order to control release of the medication, and the reservoir is filled and then closed away from the area of medication permeability.

US Classification:

623 10

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.
