The device description and intended use describe an injectable gel for vocal fold augmentation, with no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes
The device, Vocalis Gel, is indicated for vocal fold medialization and vocal fold insufficiency to improve phonation and address aspiration difficulties, which are therapeutic interventions.
No
The provided text describes Vocalis Gel as an injectable implant used for vocal fold medialization and insufficiency, which is a therapeutic intervention, not a diagnostic tool.
No
The device description clearly states it is an "injectable implant" consisting of a gel, which is a physical substance, not software.
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, solely or principally for the purpose of providing information concerning a physiological or pathological state, or a congenital abnormality, or to determine the safety and compatibility with potential recipients, or to monitor therapeutic measures.
- Vocalis Gel's Intended Use: Vocalis Gel is an injectable implant used to augment vocal folds within the body. It is a therapeutic device, not a diagnostic one. It is used to physically modify tissue to improve function (phonation and reduce aspiration), not to analyze a specimen to diagnose a condition or provide information about a physiological state.
- Device Description: The description details the composition and physical properties of an injectable gel, consistent with a medical implant.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information.
Therefore, Vocalis Gel is a medical device, specifically an implantable soft tissue bulking agent, but it does not fit the definition of an In Vitro Diagnostic.
N/A
Intended Use / Indications for Use
Vocalis Gel is indicated for vocal fold medialization and vocal fold insufficiency that may be improved by injection of a soft tissue bulking agent. Vocalis Gel injection augments the size of the displaced or deformed vocal fold so that it may meet the opposing fold at the midline for improved phonation. Vocal fold insufficiency associated with serious aspiration difficulties may be an urgent indication. The product is intended to be durable for a minimum of one month.

Device Description
Sterile, latex free, non-pyrogenic, high yield strength, isotonic, clear gel injectable implant. The gel consists primarily of sterile water for injection (USP), glycerin (USP) and mannitol (USP). The high yield strength is created by small amounts of carbomer (USP). The gel carrier allows tissue infiltration over time. All components are listed as GRAS (Generally Recognized as Safe 21 CFR 182). The character of the gel allows it to be very thick and cohesive but sheer to be easily injected through very fine needles with minimal force.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Pre-clinical tests were performed. In vivo and in vitro tests were performed to address irritation, sensitization, cytotoxicity, acute and sub-chronic toxicity, genotoxicity and hemolysis. Results identified Vocalis Gel as a non-irritant, and nontoxic with no concerns for long-term safety.
The primary risks with Vocalis Gel have been identified through a risk assessment procedure in accordance with EN 1441. The risks identified are primarily associated with nasopharyngoscopy and injection laryngoplasty.
Vocalis Gel is a safe and effective implant used as a space filling material for soft tissue augmentation in laryngeal procedures for vocal fold medialization and augmentation.

(a)
Identification. Ear, nose, and throat synthetic polymer material is a device material that is intended to be implanted for use as a space-occupying substance in the reconstructive surgery of the head and neck. The device is used, for example, in augmentation rhinoplasty and in tissue defect closures in the esophagus. The device is shaped and formed by the suregon to conform to the patient's needs. This generic type of device is made of material such as polyamide mesh or foil and porous polyethylene.(b)
