Yes
The device is indicated for "tracheoesophageal voice restoration," which is a therapeutic purpose.
No
The device is a voice prosthesis used for restoration, not diagnosis. Its function is to enable voice for patients who have undergone a total laryngectomy, and the performance studies focus on functional equivalency and safety, not diagnostic metrics.
No
The device description clearly outlines a physical, implantable voice prosthesis made primarily of silicone with mechanical components (valves, strap, flange). It also lists several physical accessory devices. There is no mention of software as the primary or sole component.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices intended for use in vitro for the examination of specimens, including blood, tissue, and urine, derived from the human body, to provide information for diagnostic, monitoring, or compatibility purposes.
- Device Function: The Blom-Singer Indwelling voice prosthesis is a physical device implanted in the body to restore voice after a laryngectomy. It facilitates airflow for speech production.
- Lack of Specimen Examination: The description does not mention the device being used to examine any biological specimens. Its function is mechanical and directly related to the physical structure of the tracheoesophageal passage.
Therefore, the Blom-Singer Indwelling voice prosthesis falls under the category of an implanted medical device, not an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use

Device Description
The Blom-Singer Dual Valve Indwelling Voice Prosthesis is provided for the same indications for use as the other Blom-Singer Indwelling Voice Prosthesis product lines. The Dual Valve Indwelling Voice Prosthesis has been modified from its predicate devices by the addition of a second valve intended to continue to function when leakage occurs in the primary valve.
The Blom-Singer Dual Valve Indwelling Prosthesis has been modified from its predicate devices by the addition of a second valve, consisting of a valve and valve seat, intended to continue to function when leakage occurs in the primary valve. The prosthesis is still primarily silicone. A second modification is the introduction of a slight tension in the voice prosthesis strap when loaded on the inserter with a gel cap containing the prosthesis' esophageal flange. When the gel cap dissolves the inserter moves forward, indicating flange deployment.
Accessory Devices: The device will be offered with the following accessories: inserter stick, flushing device, flange introducer, gel caps, and lubricant,

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Functional equivalency tests have been performed on the Blom-Singer prostheses, which demonstrate the equivalency of the valve performance with the predicate designs. Non-clinical tests referenced for a determination of substantial equivalence are Airflow, Pressure Decay, Flange Retention Force, Valve Attachment Integrity and Inserter Deployment. The conclusions drawn from the nonclinical tests demonstrate that the device is safe, as effective, and performs as well or better than the predicate devices.

§ 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 voice prosthesis is indicated for tracheoesophageal voice restoration following total laryngectomy, when placement, or replacement, of an indwelling voice prosthesis is performed by a qualified, trained medical professional.
VI TECHNOLOGICAL REQUIREMENTS
The Blom-Singer Dual Valve Indwelling Voice Prosthesis is provided for the same indications for use as its predicate devices, the Blom-Singer Indwelling 2000 Voice Prosthesis, the Blom-Singer Indwelling Low Pressure Voice Prosthesis, and the InHealth Blom-Singer Indwelling Valved Insert. All three devices are indwelling devices primarily made of silicone, designed to provide voicing after total laryngectomy. The voice prostheses are placed in a surgically-created fistula between the trachea and esophagus in order to divert air through the prosthesis valve to create 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 Dual Valve Indwelling Prosthesis has been modified from its predicate devices by the addition of a second valve, consisting of a valve and valve seat, intended to continue to function when leakage occurs in the primary valve. The prosthesis is still primarily silicone. A second modification is the introduction of a slight tension in the voice prosthesis strap when loaded on the inserter with a gel cap containing the prosthesis' esophageal flange. When the gel cap dissolves the inserter moves forward, indicating flange deployment.
Functional equivalency tests have been performed on the Blom-Singer prostheses, which demonstrate the equivalency of the valve performance with the predicate designs. Non-clinical tests referenced for a determination of substantial equivalence are Airflow, Pressure Decay, Flange Retention Force, Valve Attachment Integrity and Inserter Deployment. The conclusions drawn from the nonclinical tests demonstrate that the device is safe, as effective, and performs as well or better than the predicate devices.
Accessory Devices: The device will be offered with the following accessories: inserter stick, flushing device, flange introducer, gel caps, and lubricant,
