No
The summary describes a physical implant for surgical reconstruction and does not mention any software, algorithms, or data processing that would indicate AI/ML.

Yes
The device is used for surgical reconstruction with a partial implant, indicating a therapeutic purpose for the sound conduction chain.

No
This device is a surgical implant designed for reconstruction of the sound conduction chain, not for diagnosing a condition.

No

The device description clearly states it is a "Partial Ossicular Replacement Prosthesis," which is a physical implant, not software.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is for surgical reconstruction of the sound conduction chain in the ear. This is a surgical procedure performed on a patient's body.
  • Device Description: The device is a "Partial Ossicular Replacement Prosthesis," which is an implantable medical device used in surgery.
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or treatment.

IVD devices are used outside the body to analyze samples. This device is used inside the body during surgery.
