Intended Use

An ossicular replacement prosthesis is a device intended to be implanted for the functional reconstruction of segments of the ossicular chain and facilitates the conduction of sound wave from the tympanic membrane to the inner ear. Ossicular replacement prostheses are indicated for the functional restoration of the ossicular chain when a conductive hearing loss is present. Indications for use include: (a) Chronic middle ear disease, (b) Otosclerosis, (c) Congenital fixation of the stapes, (d) Secondary surgical intervention to correct for a significant and persistent conductive hearing loss from prior otologic surgery, and (e) Surgically correctible injury to the middle ear from trauma.

Device Story

Family of Nitinol-based ossicular replacement prostheses (ORPs) designed for middle ear reconstruction. Devices include Incudo-Stapedial Joint, Angular Piston, Piston, Malleus Piston, PORP, and Footplate Shoe. Implants facilitate sound conduction from tympanic membrane to inner ear. Used in surgical settings by otolaryngologists. Attachment via manual or heat-activated crimping. Nitinol provides shape-memory properties for secure fixation to ossicles. Benefits include restoration of hearing in patients with conductive loss. No software or electronic components.

Clinical Evidence

Bench testing only. No clinical data provided.

Technological Characteristics

Materials: Nitinol (ASTM F2063-05), Unalloyed Titanium (ASTM F67), Titanium alloy (ASTM F136), Hydroxylapatite (ASTM F1185), Fluoroplastic (ASTM D1710, ASTM F754), Medical grade silicone. Mechanical fixation via manual or heat-activated crimping. Sterile, single-use implants. No software or energy source.

Indications for Use

Indicated for patients with conductive hearing loss due to chronic middle ear disease, otosclerosis, congenital stapes fixation, prior failed otologic surgery, or middle ear trauma requiring functional reconstruction of the ossicular chain.

Regulatory Classification

Identification

You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); good manufacturing practice requirements as set forth in the quality systems (OS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050. {5}------------------------------------------------ This letter will allow you to begin marketing your device as described in your Section 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally premated nevice results in a classification for your device and thus, permits your device to proceed to the market. If you desire specific advice for your device on our labeling regulation (21 CFR Part 801), please contact the Office of Compliance at (240) 276-0115. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR Part 807.97).
