Intended Use

The Oro-Facial Myographic Measurement Instrument is intended as a diagnostic aid for the quantitative evaluation of oro-facial muscle strength. It is indicated for use in the oro-facial cavity.

Device Story

The Oro-Facial Myographic Measurement Instrument (OMMI™) is a diagnostic tool designed to measure oro-facial muscle strength. It functions as a myographic measurement instrument used within the oro-facial cavity. The device provides quantitative data to assist clinicians in evaluating muscle strength, aiding in clinical decision-making regarding patient muscle function. It is intended for prescription use.

Clinical Evidence

Bench testing only; includes pressure validation and biocompatibility evaluation.

Technological Characteristics

Myographic measurement instrument for oro-facial muscle strength. Technological characteristics are similar to mechanical dynamometers. Biocompatibility evaluated for oro-facial cavity use.

Indications for Use

Indicated for quantitative evaluation of oro-facial muscle strength in the oro-facial cavity.

Regulatory Classification

Identification

An AC-powered dynamometer is an AC-powered device intended for medical purposes to assess neuromuscular function or degree of neuromuscular blockage by measuring, with a force transducer (a device that translates force into electrical impulses), the grip-strength of a patient's hand.

Special Controls

*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 886.9.

## DEVICE NAME:

Oro-Facial Myographic Measurement Instrument (OMMI™) Class II

#### DEVICE DESCRIPTION:

The Oro-Facial Myographic Measurement Instrument (OMMI™) is a myographic measurement method for direct strength measurement of the oro-facial muscles.

### INDICATIONS FOR USE:

The Oro-Facial Myographic Measurement Instrument is intended as a diagnostic aid for the quantitative evaluation of oro-facial muscle strength.

{1}------------------------------------------------

## PREDICATE DEVICE:

John Chatillon & Sons, Inc. Dynamometer (K964685).

## TESTING in SUPPORT of SUBSTANTIAL EQUIVALENCE DETERMINATION:

The results of bench testing (Pressure Validation) and biocompatibility evaluation support the substantial equivalence claims of the OMMI™ for its intended use in the oro-facial cavity. Results of the test, in conjunction with the substantial equivalence claims as outlined in the premarket notification, effectively demonstrate the OMMI's substantial equivalence to the predicate device.

{2}------------------------------------------------

## SUBSTANTIAL EQUIVALENCE CONCLUSIONS:

Substantial equivalence is based on the fact that the Oro-Facial Myographic Measurement Instrument has the same intended use, although different indications, and similar technological characteristics as the predicate device. In instances where the technological characteristics are different, it has been demonstrated that there are no new questions raised regarding safety or efficacy of the Oro-Facial Myographic Measurement Instrument. Therefore, it can be concluded that the Oro-Facial Myographic Measurement Instrument is substantially equivalent to the predicate device.
