The description focuses on the mechanical and software control of a rotary chair for vestibular testing, with no mention of AI or ML for data analysis, interpretation, or control beyond basic software commands.
Yes
The device is used to "elicit Vestibulo-Ocular Reflexes" and for "stimulation of the patients balance organs" in order to test for "lesions in the peripheral vestibular organs," which suggests a therapeutic or diagnostic purpose related to a medical condition. The presence of a predicate device (K922037) also implies its classification as a medical device.
Yes
The device "elicit[s] Vestibulo-Ocular Reflexes in patients... who are being tested for bilateral or unilateral lesions in the peripheral vestibular organs," which is consistent with a diagnostic purpose.
No
The device description clearly states it is a rotation chair, including a chair unit and a motor pedestal unit, which are hardware components. While it is controlled by software, it is not solely software.
Based on the provided information, the Nydiag 200 rotary chair is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD devices are used to examine specimens derived from the human body. The Nydiag 200 rotary chair is used to stimulate the patient's balance organs and elicit a physiological response (Vestibulo-Ocular Reflexes) in the patient themselves. It does not analyze blood, tissue, or other bodily fluids or substances.
- The intended use describes a diagnostic procedure performed directly on the patient. The chair is used to test for lesions in the peripheral vestibular organs by observing the patient's eye movements in response to rotation. This is an in-vivo (within the living body) diagnostic method, not in-vitro (in glass/outside the body).
Therefore, the Nydiag 200 rotary chair is a diagnostic device, but it falls under the category of in-vivo diagnostic equipment, not IVD.

Intended Use / Indications for Use
The Nydiag 200 rotary chair is an optional accessory for the Interacoustics eye movement recording systems. The rotary chair is used to elicit Vestibulo-Ocular Reflexes in patients aged 2 years or older who weigh less than 135 kg / 300 lbs who are being tested for bilateral or unilateral lesions in the peripheral vestibular organs.
