Intended Use

The Nova HD+ is intended for use by adults for the stimulation of healthy muscles in order to improve or facilitate muscle performance.

Device Story

Nova HD+ is a noninvasive powered muscle stimulator using electrically generated magnetic fields to stimulate healthy muscles. System comprises a main control unit and a large loop coil applicator. Operated by user or clinician in home or clinical settings. User selects treatment duration (1-20 minutes) and intensity (levels 1-10) via control unit interface.

Above the word "AURA" is a circular design made up of many small, colored dots. The dots are arranged in concentric circles, with the colors ranging from green and blue on the outside to purple, orange, and yellow in the center.

#### VII Equivalence Rationale

## Principle of Operation

The principle of operation for the Nova HD+ is identical to the predicate, Bemer Classic Set and Bemer Pro-Set (K210174). The Nova HD+ and the predicate systems deliver therapeutic massage to the patient through the use of low-level magnetic fields administered directly to the body.

## Use Mode

The use of the Nova HD+ is essentially the same as the predicate device. Both units have main control units have interchangeable treatment applicators (coils) for administering the therapy to desired area of the controls on the control unit allow the user to select the time and intensity of the therapy and allow for adjustment of the intensity during the session.

## Non-clinical Testing

Performance testing demonstrated that the subject treatment applicator performed equivalent to the predicate applicator. Testing included:

Performance testing involved multiple measurements of:

- Signal waveform output (volts) generated from Nova HD+ with its applicators. ●
- Magnetic flux output (mT) generated from the applicator at all signal intensity input levels 1-10.

## Software

- All software features documented and tested in accordance with IEC 62304 for 'Moderate' level of concern.
Electrical / EMC evaluated per

## CONCLUSIONS

The analysis of the differences between Nova HD+ and the predicate device does not raise new questions of safety and effectiveness for the subject device performance test results, Aura Wellness determines that the Nova HD+ system performs within its design specifications and is equivalent to the predicate device.

The information in this 510(k) submission demonstrates that the Nova HD+ system is substantially equivalent to the predicate device.
