The description focuses on the physical materials and design of the ossicular implants, with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes
The device is described as an implant used for the elective reconstruction of the ossicular chain to facilitate conduction of sound energy, bridging complete auditory ossicle defects, which indicates it restores or improves a physiological function (hearing).
No
The device is an implantable prosthesis intended for the reconstruction of the ossicular chain, meaning it's used to treat a condition rather than diagnose one.
No
The device description clearly states it is a physical implant made of gold and titanium, intended for surgical implantation. It is a hardware device, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Device Function: The KURZ Aerial implants are implants designed to physically reconstruct the ossicular chain in the middle ear. They are surgically placed within the body to restore sound conduction.
- Intended Use: The intended use clearly states the device is for "elective reconstruction of the ossicular chain to facilitate conduction of sound energy." This is a mechanical function within the body, not an analysis of a specimen outside the body.
- Device Description: The description details the physical components of the implant (gold/titanium mesh, shaft, bell/piston). There is no mention of reagents, test strips, or any components used for analyzing biological samples.
- Anatomical Site: The device is implanted in the "Middle ear," which is an internal anatomical site, not a source of specimens for in vitro testing.
The information provided clearly describes a surgical implant, not a device used for in vitro diagnostic testing.
N/A
Intended Use / Indications for Use
The KURZ Aerial implants are intended for the elective reconstruction of the ossicular chain to facilitate conduction of sound energy from the ear drum to the inner ear. The prosthesis is implanted into the middle ear during a tympanoplasty procedure and is retained in the middle ear by the design configuration of the device and the favorable biocompatible characteristics of gold and titanium.
Ossicle replacement in case of interrupted sound conducting chain and intact, mobile stapes footplate.
The Aerial Total Prosthesis is intended for bridging a complete auditory ossicle defect.
The prosthesis is placed on the basis of the stapedis and the defect is bridged as far as the ear drum or up to the manubrium mallei.

Device Description
Standard The implant consists of a golden wire rectangle Gold a. with a structured outer surface and a stem which is available in various lengths. It ends in a 'bell' with two slits.
Dresden The implant consists of an extremely thin mesh plate made of gold and a thin shaft, which is available in different lengths. It has a split piston at the end.
Titanium Düsseldorf The implant consists of a titanium mesh plate b. that is textured on the surface that makes contact with the tympanum and a shaft that is available in various lengths.
Tübingen The prosthesis consists of a titanium mesh plate that is connected eccentrically with a shaft available in various lengths. A hollow piston, open at the bottom, the inside of which is also textured, is located at the end of the shaft.
The device is a single patient use only implant. It comes in an individual sterile package in a sealed carton.

§ 874.3495 Total ossicular replacement prosthesis.
(a)
Identification. A total ossicular replacement prosthesis is a device intended to be implanted for the total functional reconstruction of the ossicular chain and facilitates the conduction of sound waves from the tympanic membrance to the inner ear. The device is made of materials such as polytetrafluoroethylene, polytetrafluoroethylene with vitreous carbon fibers composite, porous polyethylene, or from a combination of these materials.(b)
Classification. Class II.

The device is a single patient use only implant. It comes in an individual sterile package in a sealed carton.
Intended Use of Device {{807.92(a)(5)] (5)
The KURZ Aerial implants are intended for the elective reconstruction of the ossicular chain to facilitate conduction of sound energy from the ear drum to the inner ear. The prosthesis is implanted into the middle ear during a tympanoplasty procedure and is retained in the middle ear by the design configuration of the device and the favorable biocompatible characteristics of gold and titanium.
The device can be used on adults and children.
(6) Technological Characteristics [807.92(a)(6)]
The implants can be bent and easily shaped to the individual conditions in the middle ear, yet hold their shape after placement.
(7) Information Bearing on the Safety and Effectiveness
The KURZ Aerial total ossicular replacements have the same intended use as predicate devices. There are no additional characteristics known that should adversely affect the safety and effectiveness of these implants.

Dear Mr. Maser:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, 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 misbranion.
If your device is classified (see above) into either class III (Premarket Approval), it may be subject * 1 such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under Radiation Control provisions, or other Federal laws or regulations.
This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.
