The summary describes a mechanical prosthesis made of Nitinol and titanium, relying on material properties (shape memory) and mechanical design for its function. There is no mention of software, algorithms, or data processing that would indicate the use of AI/ML.
Yes
The device is a prosthesis intended to restore functionality to the middle ear by replacing ossicular structures, which is a form of therapeutic intervention for pathological changes in the sound transmission system.
No
This device is a prosthesis intended for surgical implantation to restore functionality to the middle ear, not to diagnose a condition.
No
The device is a physical prosthesis made of Nitinol and titanium, intended for surgical implantation in the middle ear. The description details the materials, physical components (loop, piston), and mechanical properties (shape memory). It also mentions an accessory (Thermo-Dummy) and performance testing related to physical characteristics and biocompatibility. There is no mention of software as the primary or sole component of the device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for the diagnosis, treatment, or prevention of disease.
- Device Function: The described device is a stapes prosthesis, which is an implantable medical device used to physically replace or repair a damaged part of the middle ear's sound transmission system. It directly interacts with the patient's anatomy to restore function.
- Intended Use: The intended use clearly states that the prostheses are for "partial ossicular replacement to restore functionality to the middle ear." This is a surgical intervention, not a diagnostic test performed on a specimen outside the body.
The device is a surgical implant, not a diagnostic tool that analyzes biological samples.
N/A
Intended Use / Indications for Use
The prostheses are intended for partial ossicular replacement to restore functionality to the middle ear in cases of pathological changes of the sound transmission system. The NiTiBOND Stapes Prosthesis act as a bridge between the long process of the incus and the base of the stapes, with the piston extending into the perilymphatic space of the inner ear.
The loop consists of a nickel-titanium alloy (Nitinol), while the piston is made of pure titanium.
Specifically, the devices are designed for the treatment of
- Otosclerosis (stapedial fixation) / congenital stapedial fixation
- Traumatic injury to the ossicular chain
- Malformation of the middle ear
- Revision surgery to correct inadequate hearing improvement, e.g. through dislocation of a prosthesis

Device Description
The stapes prosthesis consists of a Nitinol loop and the standard KURZ shaft made of pure titanium (ASTM F67).
The flat loop band diffuses the impact of pressure on the incus. When applying heat to the ContactFree Zones, the shape memory features of Nitinol cause the loop to close. The ContactFree Zones serve as heat blockers, limit heat dispersion on the mucosa and minimize the risk of incus s-tranqulation. The prosthesis comes with an accessory, the Thermo-Dummy®, to predetermine the lowest laser setting that will close the prosthesis loop outside the patient's ear before inserting the implant.

[807.92 (b)(3)]
The differences between the KURZ NiTiBOND Stapes Prosthesis and the predicate devices are designed to enhance the safety and effectiveness of stapedotomy procedures.
Nonclinical and clinical testing demonstrate that the KURZ NiTiBOND is as safe and effective as the predicate devices.
There are no known characteristics that would introduce adverse effects.
The results of non-clinical and clinical design and performance validations raise no new issues of safety and effectiveness.
