The description focuses on standard tympanometry and reflex testing techniques and does not mention any AI/ML components or algorithms. The performance studies are related to safety, EMC, and bench testing against standards, not AI/ML model validation.
No
The device is used for detection of possible otologic disorders and measurement, not for treatment.
Yes
The "Intended Use / Indications for Use" section explicitly states that the device is designed for "detection of possible otologic disorders" and performs measurements (Tympanometry and Reflex tests) for this purpose.
No
The device description explicitly states it is a "small desk-top device" powered by mains or batteries, includes a probe, transducer, integral screen, and connections for PC and printer, indicating it is a hardware device with embedded software (firmware).
Based on the provided information, the Amplivox Otowave 202 is not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro (outside the body) to examine specimens, including blood, tissue, and urine, from the human body to provide information for diagnosis, monitoring, or screening.
- Amplivox Otowave 202 Function: The Amplivox Otowave 202 performs measurements in vivo (within the body) by applying stimuli to the ear canal and measuring the response of the tympanic membrane and middle ear. It does not analyze biological specimens.
- Intended Use: The intended use clearly states it's for "detection of possible otologic disorders... associated with the functioning of the middle ear" by performing measurements directly on the patient.
Therefore, the Amplivox Otowave 202 is a medical device, but it falls under a different classification than an IVD. It is a diagnostic device that performs measurements directly on the patient's body.

Intended Use / Indications for Use
The Amplivox Otowave 202 is designed for use by trained operators (audiologists, general practitioners, hearing aid dispensers, and child health professionals) in hospitals, ENT clinics, and audiologist offices for the detection of possible otologic disorders in the general population associated with the functioning of the middle ear. The instrument performs two types of measurement: Tympanometry is used to measure the tympanic membrane and middle ear at a fixed frequency over a range of pressures. Reflex tests are used to measure stapedial reflexes. The Otowave measures ipsilateral reflexes and, when selected, reflex measurement is automatically carried out after a tympanogram is taken.

Device Description
The Otowave 202 relies heavily on long-established practice in the clinical area of middle-ear measurements, and implements tympanometer functionality in a small desk-top device that may be powered from the mains (via a d.c. adapter) or by internal batteries. Stimuli are applied to the patient by means of a probe mounted on a flexible connecting lead for ease of use (especially with neonates) and additional contralateral stimuli are available if required via a separate plug-in transducer. Operation is via an intuitive menu-driven user interface, with test data displayed on the integral screen and capable of download to a PC via a USB connection and to a printer via an infrared communications (IrDA) interface. Tympanometers work by measuring the admittance of the tympanic membrane while the pressure in the ear canal is varied. The admittance is at a maximum when the air pressure across the tympanic membrane is balanced.

§ 874.1090 Auditory impedance tester.
(a)
Identification. An auditory impedance tester is a device that is intended to change the air pressure in the external auditory canal and measure and graph the mobility characteristics of the tympanic membrane to evaluate the functional condition of the middle ear. The device is used to determine abnormalities in the mobility of the tympanic membrane due to stiffness, flaccidity, or the presence of fluid in the middle ear cavity. The device is also used to measure the acoustic reflex threshold from contractions of the stapedial muscle, to monitor healing of tympanic membrane grafts or stapedectomies, or to monitor followup treatment for inflammation of the middle ear.(b)
Classification. Class II (special controls). The device, when it is a tympanometer or auditory impedance tester that complies with FDA-recognized consensus standard ANSI S3.39, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 874.9.

- Summary of clinical testing: Not applicable. Not required to establish substantial equivalence.
- Conclusion: After analyzing bench testing, safety, EMC, and software validation (with risk 9. analysis) testing we conclude that the Otowave 202 is as safe and effective as the predicate device, and has essentially the same technological characteristics, thus rendering it substantially equivalent to the predicate device.
