No
The summary describes a mechanical ossicle replacement prosthesis made of titanium and does not mention any software, algorithms, or AI/ML capabilities.
Yes
The device is intended for ossicle replacement to restore sound conduction, which is a therapeutic intervention.
No
This device is an ossicle replacement prosthesis, which is a therapeutic device designed to restore the sound-conducting chain, not to diagnose a condition.
No
The device description clearly states it is a physical prosthesis made of titanium, consisting of a clip, shaft, and head plate. This indicates 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 perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health. These tests are performed outside of the body.
- Device Description and Intended Use: The provided information describes a titanium prosthesis intended for surgical implantation in the middle ear to replace ossicles and restore sound conduction. This is a device that is surgically placed inside the body to perform a mechanical function.
The device's function is to physically replace damaged ossicles within the middle ear, not to analyze biological samples for diagnostic purposes.

Device Description
The all-titanium prosthesis consists of a clip with seven (7) resilient prongs, a shaft, and a head plate. Holding the device vertically to the stapes axis, the clip is gently pushed over the stapes head so that the titanium prongs with their built-in tension securely grasp the stapes head and upper part of the stapes and the two somewhat shorter rear prongs are positioned on either side of the stapedial tendon. The head plate is covered with a thinned cartilage slice and placed under the manubrium mallei or under the tympanic membrane.

§ 874.3450 Partial ossicular replacement prosthesis.
(a)
Identification. A partial 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. The device is made of materials such as stainless steel, tantalum, polytetrafluoroethylene, polyethylene, polytetrafluoroethylene with carbon fibers composite, absorbable gelatin material, porous polyethylene, or from a combination of these materials.(b)
Classification. Class II.

Tübinger Straße 3 The all-titanium prosthesis consists of a clip with seven (7-72144 Dussinge resilient prongs, a shaft, and a head plate. Telefon (0 70 72) 91
Reasons for Device Modification: [807.92 (d)] 2.8 Material:
Internet:
- http://www.kurzme Titanium provides excellent sound conduction even E-Mail: info@kurzm at higher frequencies
- Due to the lower specific weight of titanium, the 2. device is substantially lighter than the gold KURZ Bell "Dresden" prosthesis
Design:
By pushing the elastic clip over the stapes head and upper part of the stapes, a more secure connection is established that not only eliminates the need for device manipulation in situ but also the chance of implant dislocation with a high degree of certainty.
2.9 Intended Use: [807.92 (a)(5)]
Ossicle replacement in case of interrupted sound conducting chain in patients with intact, mobile stapes
Industry Standards: [807.92 (d)] 2.10
KURZ certifies compliance with all appropriate industry standards and the validation of methods and processes covered by these standards.
2.11 MRI Environment: [807.92 (d)]
Testing in a 0.5 Tesla nuclear magnetic resonance (NMR) tomograph has revealed no implant movement and no adverse tissue effects attributable to MRI-generated heating.
Information Bearing on the Safety and Effectiveness: 2.12
[807.92 (b)(3)]
The KURZ Clip Partial Prosthesis -- Titanium "Dresden" has the same intended use as the previously cleared device made of pure gold. With the exception of the described material and design changes, there are no additional characteristics known that should adversely affect the safety and effectiveness of these implants.
The results of design validation raise no new issues of safety and effectiveness.

Changes
[807.92 (b)(1)] | Titanium is a clinically well-
established implant material with
excellent biocompatibility. The
much lighter weight appears to
be better suited for implantation
in the middle ear. Clinical
evidence suggests that titanium
has excellent sound conduction
properties resulting in improved
hearing gain.
The tensile clip mechanism
significantly reduces the risk of
implant implant dislocation while
the secure but vibrant connection
to the stapes head is expected to
improve long-term hearing gains
with appropriate physiological
conditions.
