Intended Use

The miraDry System is indicated for use in the treatment of primary axillary hyperhidrosis. Note: The miraDry System is not indicated for treating hyperhidrosis related to other body areas or generalized hyperhidrosis.

Device Story

The miraDry System is a microwave-based device used to treat primary axillary hyperhidrosis by heating tissue at the dermal-hypodermal interface where sweat glands reside. The system comprises the DTS3000 console, a handpiece, and a sterile, disposable bioTip. The console includes a microwave generator, vacuum system, cooling system, and touch-screen interface. The handpiece delivers microwave energy to the skin while the bioTip provides a sterile barrier. The device is operated by a clinician in a clinical setting. The system provides controlled thermal energy to target sweat glands; the healthcare provider uses the interface to manage energy delivery. The treatment aims to reduce sweat production, providing clinical benefit to patients with primary axillary hyperhidrosis.

Clinical Evidence

Clinical evidence includes a randomized, blinded study of 120 subjects with primary axillary hyperhidrosis. The study compared treated subjects (n=81) to sham-treated subjects (n=39). The primary endpoint was met, demonstrating a statistically significant difference in sweat reduction efficacy. Adverse events were generally mild and resolved, with one exception.

Technological Characteristics

Microwave-based tissue heating system. Components: DTS3000 console, handpiece, disposable sterile bioTip. Features integrated vacuum and cooling systems. Conforms to IEC 60601-1, 60601-1-2, 60601-1-4, 60601-1-6, 60601-2-2, and 60601-2-6. Biocompatible patient-contacting materials. Software-driven console with touch-screen interface.

Indications for Use

Indicated for treatment of primary axillary hyperhidrosis. Not indicated for generalized hyperhidrosis or other body areas.

Regulatory Classification

Identification

miraDry System

Console: the miraDry Handpiece; and a disposable, sterile miraDry bioTip that snaps onto the Handpiece to provide a sterile protective cover.

The DTS3000 Console is a software-driven device which contains circuit boards, a microwave generator, integrated vacuum and cooling systems, and an integrated touch-screen user interface.

The non-invasive miraDry Handpiece is specifically designed to deliver microwave energy to the skin at specified frequency and power levels. The proximal end of the Handpiece has a cable bundle and console connector that supplies the energy and cooling to the Handpiece. The distal end has a sterile, disposable barrier, the miraDry bioTip, that contacts the patient.

### Materials

All materials used in the manufacture of the miraDry System are suitable for this use and have been used in numerous previously cleared products. Patient-contacting materials have been demonstrated to be biocompatible.

### Performance Testing

Product and animal testing was conducted to ensure conformance to product specifications, and equivalence to the predicate device. In particular, animal testing demonstrated that thermal zones created with the predicate device were similar to those created with the miraDry System.

The miraDry System has been shown to conform to the applicable requirements of the following:

- IEC 60601-1: (1988 + A1:1991 + A2:1995) Medical Electrical Equipment . Part 1: General Requirements for Safety Requirements for Medical Electrical Systems
- IEC 60601-1-2: (2001+A1:2004) Medical Electrical Equipment Part 1-2: . General Requirements for Safety: Electromagnetic Compatibility
- IEC60601-1-4:2000. Medical Electrical Equipment Part 1-4 General . requirement for safety - Collateral Standard: Programmable electrical medical systems
- IEC60601-1-6:2004. Medical electrical equipment Part 1-6: General . requirements for safety - Collateral Standard: Usability
- IEC 60601-2-2:2006. Medical electrical equipment Part 2-2: Particular . requirements for the safety of High Frequency Surgical Equipment
- IEC 60601-2-6:1984. Medical electrical equipment Part 2: Particular . requirements for the safety of microwave therapy equipment.

Clinical testing showed that the device provides a safe and effective means to treat axillary hyperhidrosis. A randomized, blinded study with 120 subjects with primary axillary hyperhidrosis was conducted. The study primary endpoint was met, which demonstrated a statistically significant difference in sweat

reduction efficacy between the treated subjects (n=81) and the subjects that received a sham treatment (n=39). Adverse events were generally mild in severity and all but one (persistent hyperhidrosis on the face) resolved.

## Summary of Substantial Equivalence

The miraDry System is substantially equivalent to the predicate product for the following reasons:

- 1. The miraDry System has the same intended use as the legally marketed DTS G2 System, i.e., a localized and controlled heating of soft tissue.
- 2. The indication for use for the miraDry System is a specific indications for use within the "functional" indications for use for the DTS G2 System that were cleared by FDA, i.e., "The DTS G2 System is indicated for use for coagulation of soft tissue".
- 3. The materials used in the miraDry System, the device's methods of manufacturing and overall function are the same as the FDA cleared DTS G2 System.
- 4. While the miraDry System has the same intended use and basic technological characteristics as the predicate, the specificity of the miraDry System's indications for use prompted Miramar Labs to conduct a clinical study to ensure that the performance specifications of the device met user needs. On the basis of direct comparison with the predicate device and the results of preclinical and clinical testing, the miraDry System has been demonstrated to be substantially equivalent to the legally marketed DTS G2 System.
