Intended Use

The VF Gel Plus is indicated for vocal fold medialization in the treatment of vocal fold insufficiency, where insufficiency may be improved by injection of a soft tissue bulking agent. VF Gel Plus injection augments the size of the displaced or deformed vocal fold so that it may meet the opposing fold at the midline for improved glottal closure. Improved glottal closure may allow improved phonation, improvement of cough, and an improved ability to protect the airway during swallowing. VF Gel Plus is a temporary implant that degrades over time. The product is intended to be durable for a minimum of one month.

Device Story

VF Gel Plus is a sterile, semi-solid, cohesive subdermal implant used for vocal fold medialization. It consists of synthetic calcium hydroxylapatite particles (25-45 microns, 30% by volume) suspended in a thixotropic gel carrier (sterile water, glycerin, mannitol, and carbomer). The device is injected into the vocal fold to augment its size, enabling the displaced or deformed fold to meet the opposing fold at the midline. This improves glottal closure, phonation, cough, and airway protection during swallowing. It is a temporary, degradable implant intended to be durable for at least one month. The device is intended for clinical use by a physician.

Clinical Evidence

Bench testing only. Performance evaluations and comparison testing were conducted to substantiate the indications for use and demonstrate substantial equivalence to the predicate device.

Technological Characteristics

Subdermal implant; synthetic calcium hydroxylapatite particles (25-45 microns) in a thixotropic gel carrier (sterile water, glycerin, mannitol, carbomer). Sterile, latex-free, non-pyrogenic. Semi-solid, cohesive form factor.

Indications for Use

Indicated for patients with vocal fold insufficiency requiring vocal fold medialization via soft tissue bulking agent injection to improve glottal closure, phonation, cough, and airway protection.

Regulatory Classification

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.

## DEVICE DESCRIPTION

Sterile, latex free, non-pyrogenic, semi-solid, cohesive subdermal implant. The principal durable component is synthetic calcium hydroxylapatite. The semi-solid nature is created by suspending the calcium hydroxylapatite particles in a high yield strength thixotropic gel. The isotonic gel carrier consists primarily of sterile water for injection (USP), glycerin (USP) and mannitol (USP). The thixotropic high yield strength gel is created by the carbomer (NF). The calcium hydroxylapatite particles are 25 to 45 microns in size while being smooth but irregular in shape and are present in the product at 30% by volume.

# INTENDED USE STATEMENT

The VF Gel Plus is indicated for vocal fold medialization in the treatment of vocal fold insufficiency, where insufficiency may be improved by injection of a soft tissue bulking agent. VF Gel Plus injection augments the size of the displaced or deformed vocal fold so that it may meet the opposing fold at the midline for improved glottal closure. Improved glottal closure may allow improved phonation, improvement of cough, and an improved ability to protect the airway during swallowing. VF Gel Plus is a temporary implant that degrades over time. The product is intended to be durable for a minimum of one month.

## SUBSTANTIAL EQUIVALANCE COMPARISON

#### 1. Indications Summary

The "Indication Statement" for the VF Gel Plus is substantiated by the results of the performance evaluations and comparison testing to the predicate device. The differences between the Subject and the Predicate do not affect.the safety and effectiveness of the VF Gel Plus.

#### 2. Technological Characteristics Summary

The VF Gel Plus is substantially equivalent in design, materials and fundamental scientific technology to the predicate device. Any differences between the Subject and the Predicate device are minor and do not raise issues regarding safety or effectiveness.

#### 3. Performance Summary

The VF Gel Plus performance data meet the applicable standards and fulfill the device requirements as defined in the user specifications.

#### SUBSTANTIAL EQUIVALENCE CONCLUSION

Based on the design, materials, function, intended use, and performance evaluations discussed herein, Coapt Systems believes the VF Gel Plus is substantially equivalent to the predicate device currently marketed under the Federal Food, Drug and Cosmetic Act. No new issues of safety or effectiveness were raised for the VF Gel Plus Device. Therefore, safety and effectiveness are reasonably assured, justifying 510(k) clearance for commercial sale.
