The summary describes a mechanical voice prosthesis and its accessories. There is no mention of software, algorithms, or any technology that would typically incorporate AI/ML.
Yes
The device is described as a "Voice Rehabilitation System" intended for "prosthetic voice rehabilitation after total laryngectomy," indicating its use in restoring or improving a physiological function.
No
Explanation: The device is described as a voice prosthesis used for rehabilitation after total laryngectomy, not for diagnosing a condition. Its purpose is to facilitate prosthetic voice, which is a therapeutic function.
No
The device description explicitly states it is a "non-indwelling (Standard) voice prosthesis equipped with a safety medallion, an insertion tool and some accessories," and mentions different sizes and a re-usable inserter, indicating it is a physical medical device with hardware components.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "prosthetic voice rehabilitation after total laryngectomy." This is a therapeutic and rehabilitative purpose, not a diagnostic one.
- Device Description: The device is a "non-indwelling (Standard) voice prosthesis." This is a physical device used to facilitate speech, not to perform tests on biological samples.
- Lack of IVD Characteristics: The description does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Providing information about a patient's health status, disease, or condition based on in vitro testing.
- Using reagents or assays.
The device is a medical device used for rehabilitation, not for in vitro diagnostic testing.

Device Description
The Provox® NID™ Rehabilitation System is a non-indwelling (Standard) voice prosthesis equipped with a safety medallion, an insertion tool and some the accessories.
The Provox NID voice prosthesis is available in two outer diameters (17 and 20 French) and six different lengths, (6, 8, 10, 12, 14 and 18 mm). Each prosthesis comes individually packed with a re-usable inserter. The design of the device is based on the indwelling voice prostheses Provox1, Provox2 and ActiValve.

Performed by Princess Alexandra Hospital, Brisbane, Australia. The Human Clinical Test Research Ethics Committee of the hospital approved the study. All of the patients were using the Blom-Singer Low Pressure Voice Prosthesis prior to this study. In total, 14 patients participated in this clinical trail.
Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Test results support the conclusion that the actual device performance satisfies the design intent. Functional equivalency test have been performed on the three prostheses, which demonstrate the equivalency of the valve performance with the three designs.

§ 874.3730 Laryngeal prosthesis (Taub design).
(a)
Identification. A laryngeal prosthesis (Taub design) is a device intended to direct pulmonary air flow to the pharynx in the absence of the larynx, thereby permitting esophageal speech. The device is interposed between openings in the trachea and the esophagus and may be removed and replaced each day by the patient. During phonation, air from the lungs is directed to flow through the device and over the esophageal mucosa to provide a sound source that is articulated as speech.(b)
Classification. Class II (special controls). The device, when it is a voice amplification device, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 874.9.

All of the patients were using the Blom-Singer Low Pressure Voice Prosthesis prior to this study. In total, 14 patients participated in this clinical trail. Test results support the conclusion that the actual device performance satisfies the design intent. The proposed device is substantially equivalent to the legally marketed predicate Technological Characteristics devices in design, intended use and materials of manufacturer. The Provox® NID™ Rehabilitation System is provided for the same indications for use as its predicate devices, the Provox®2 Voice Prosthesis System and the Blom-Singer Low Pressure Voice Prosthesis. All three devices are designed to provide voicing after total laryngectomy. The devices are placed in a surgically created fistula between the trachea and esophagus in order to divert air through the
prosthesis valve to created voicing.
Functional equivalency test have been performed on the three prostheses, which demonstrate the equivalency of the valve performance with the three designs.
