No
The device description and intended use are purely mechanical, describing physical prostheses for ossicular chain reconstruction. There is no mention of software, algorithms, data processing, or any terms related to AI/ML.
Yes
The device is used for ossicle replacement to restore middle ear function, which is a therapeutic intervention aimed at treating a medical condition and improving patient health.
No
This device is described as a reconstruction prosthesis used to restore middle ear function by replacing missing or malformed ossicles, indicating a treatment or surgical function rather than a diagnostic one.
No
The device description explicitly states the system consists of "various implants, instrumentation, and storage containers," which are physical hardware components, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
- Device Description and Intended Use: The description clearly states that these are implants (prostheses) used for surgical reconstruction of the ossicular chain in the middle ear. They are physically placed within the body to restore mechanical function.
- Lack of Diagnostic Testing: There is no mention of this device being used to analyze samples or provide diagnostic information about a patient's condition. Its purpose is purely therapeutic and reconstructive.
Therefore, the Lelbinger titanium ossicular chain reconstruction prostheses and accessories fall under the category of implantable surgical devices, not In Vitro Diagnostics.

§ 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.
