No
The description focuses on material composition, mechanical design, and functional performance of a voice prosthesis, with no mention of AI or ML.
Yes
The device is described as being for "voice rehabilitation following total laryngectomy," indicating its purpose is to restore or improve a physiological function (speech) that has been impaired by a medical condition (laryngectomy).
No
Explanation: The device is a voice prosthesis used for rehabilitation following a laryngectomy. Its purpose is to facilitate speech, not to diagnose a medical condition.
No
The device description clearly states it is made of medical grade silicone elastomer and is comprised of physical components like a body, flanges, a strap, and a flap valve. This indicates a physical medical device, not a software-only one.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "voice rehabilitation following total laryngectomy where placement/replacement of the voice prosthesis is done by a clinician." This describes a device used in vivo (within the body) for a therapeutic purpose (voice rehabilitation).
- Device Description: The description details a physical prosthesis made of silicone elastomer with flanges and a valve, designed to be implanted. This is consistent with an implantable medical device, not a diagnostic test performed on samples in vitro (outside the body).
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting analytes, or providing diagnostic information.
The mention of "in-vitro studies" for the antibacterial properties of an additive refers to testing the material's properties in a lab setting, not the device itself being an IVD.

Intended Use / Indications for Use
The Blom-Singer Indwelling 2000 Voice Prosthesis is for voice rehabilitation following total laryngectomy where placement/replacement of the voice prosthesis is done by a clinician. The Blom-Singer Indwelling 2000 Voice Prosthesis may be placed at the time of surgery or may be placed at a later date secondary to the laryngectomy.

Device Description
The design of the Blom-Singer Indwelling 2000 Voice Prosthesis is substantially equivalent to the current Blom-Singer Indwelling Low Pressure Voice Prosthesis. Both devices are manufactured sterile and nonsterile, out of medical grade silicone elastomer, and are comprised of a body with an outer esophageal flange and a tracheal flange with a strap. Both devices utilize a flap valve to control the passage of air through the device. The Blom-Singer Indwelling 2000 has the addition of an assembled cartridge, consisting of a valve seat, to optimize the valve performance and longevity. The valve now has an additive which has demonstrated antibacterial properties in in-vitro studies.
To aid in placing the gel cap onto the device, the esophageal flange on the outer portion of the device has been modified. The esophageal flange now has contoured areas, which allow the flange to fold along the contours for easy insertion into a gel cap for atraumatic placement of the device.

§ 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.

V. INTENDED USE
The Blom-Singer Indwelling 2000 Voice Prosthesis is for voice rehabilitation following total laryngectomy where placement of the voice prosthesis is done by a clinician.
The Blom-Singer Indwelling 2000 Voice Prosthesis may be placed at the time of surgery or may be placed at a later date secondary to the laryngectomy.
VI. TECHNOLOGICAL CHARACTERISTICS
The Blom-Singer Indwelling 2000 Voice Prosthesis is provided for the same indications for use as its predicate devices, the Blom-Singer Indwelling Low Pressure Voice Prosthesis and the Provox 2 Voice Prosthesis. All three devices are indwelling devices 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. The use of an indwelling device means that routine removal for cleaning by the patient is not necessary, thus making it easier for the patient to maintain the device while reducing the risk of accidental dislodgment of the device.
The Blom-Singer Indwelling 2000 Voice Prosthesis has been modified from its predicate device by the addition of the assembled cartridge, consisting of a valve and valve seat, to isolate the valve and valve seat from tissue contact. The valve has an antibacterial additive.
Functional equivalency tests have been performed on the two Blom-Singer prostheses, which demonstrate the equivalency of the valve performance with the two designs.
Accessory Devices: The Blom-Singer Indwelling 2000 Voice Prosthesis will be offered with the following accessories as optional items:
The Inserter Tool and Gel Caps
Blom-Singer Flushing Device.
Blom-Singer Brush
Blom-Singer Plug Insert .
