## CLASSIFICATION NAME: 21 CFR 884.5160 (Powered breast pump)

## PRODUCT CODE: HGX (Pump, Breast, Powered)

### PREDICATE DEVICE:

K151632; Medela Symphony Breast Pump. The predicate device has not been subject to a design-related recall.

### DEVICE DESCRIPTION:

The Sonata™ breast pump and kit are used to express and collect mills from the breast of a lactating woman. The system is intended for daily use in a home (or similar environment such as an office) to supplement breastfeeding by a single user. The system is not designed for mobile use. Pumping with the Sonata™ breast pump can be performed on one breast (single pumping) or on both breasts at the same time (double pumping).

Two suction rhythms are pre-programmed with variable vacuum levels and cycle rates (pump speed). The Sonata™ breast pump is capable of providing vacuum levels from -50 to -240 mmHg with cycle rates up to 120 cycles per minute.

The Sonata™ breast pump provides the following user features:

- Gear-driven vacuum pump design (linear piston), for quiet operation.
- LCD display, for user assistance/device status.
- Capacitive touch controls for user adjustment of vacuum level/cycles, phase selection "Letdown", pattern selection, and audio chimes.
- 2-Phase Expression® Technology designed to mimic a baby's natural nursing rhythm:
- . Stimulation Phase (phase 1): Suction pattern with fast cycles and low vacuum to start milk flowing
- . Expression Phase (phase 2): Suction pattern with slower cycles and higher vacuum to express more milk gently and efficiently.
- "Let-down" control to change between stimulation phase and expression phase.
- Option of either single or double breast pumping.
- Protective membrane, designed to isolate the pump mechanism from the breast milk collection apparatus (prevent milk overflow into the pump). No vacuum can be created if the protective membrane is missing or damaged.
- User-friendly pump exterior, designed for ease of cleaning.

## INDICATIONS FOR USE:

The Sonata™ breast pump is a powered breast pump to be used by lactating women to express and collect milk from their breast. The Sonata breast pump is intended for a single user.

### DETERMINATION OF SUBSTANTIAL EQUIVALENCE:

#### SUMMARY OF TECHNOLOGICAL CHARACTERISTICS OF THE DEVICE COMPARED TO THE PREDICATE DEVICE

The indications for use of Medela's Sonata™ breast pump are the same as the predicate devices with the additional statement that it is intended for a single user. The subject and predicate device have the same intended use – to express and collect milk from the breast.

Sonata™ and the predicate device generate vacuum in a similar manner. A microprocessorcontrolled DC motor provides motive force to a drive train which in turn moves a linear element to create volumetric expansion and vacuum.

The table below identifies key similarities and differences of the proposed Sonata breast pump to the legally marketed predicate device, the Symphony breast pump (K151632).

## TABLE 1. COMPARISON OF SONATA TO PREDICATE DEVICE

{6}------------------------------------------------

{7}------------------------------------------------

{8}------------------------------------------------

{9}------------------------------------------------

The technological characteristics of the subject device are different – the subject device utilizes a different vacuum pumping mechanism, has a different user interface, different material components, batteries, dimensions, weight, operating and storage temperature/humidity, suction levels, cycle speeds, and overflow protection mechanisms. However, different types of safety or effectiveness questions are not raised by these differences in technological characteristics.

## SUMMARY OF NON-CLINICAL TESTS:

The Sonata breast pump complies with voluntary standards for electrical safety, electromagnetic compatibility, use in the home healthcare environment and usability. The following data were provided in support of the substantial equivalence determination:

- Risk Analysis developed in accordance with ISO 14971:2007 Medical devices – Application of risk management to medical devices.
- . Biocompatibility Evaluation was completed according to the FDA guidance "Use of International Standard ISO- 10993, Biological Evaluation of Medical Devices Part 1: Evaluation and Testing" and concluded that no new testing was required as all patient contacting materials are identical to those used in the predicate Symphony Breast Pump.
- . Software verification and validation testing were conducted and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." The software for this device was considered as a "moderate" level of concern, since prior to mitigations of hazards, failure of the software could lead to minor injury, such as pain or engorgement.

{10}------------------------------------------------

- . Electrical safety and electromagnetic compatibility testing per IEC 60601-1:2005 (3rd Edition) with US deviations per AAMI/ANSI ES60601-1:2005/(R)2012 and A1:2012 standard and IEC 60601-1-2: 2014 standards, respectively
- . Safety testing for use in the home per IEC 60601-1-11: 2010 standard
- . Performance Testing to determine the vacuum performance, including minimum and maximum vacuum levels for the pump as compared to the predicate device, vacuum stability, battery performance, overflow performance, design life, durability, and acoustic testing.

# CONCLUSION:

The differences between the Sonata breast pump and its predicate device do not introduce a new intended use and do not raise new issues of safety and effectiveness. Verification and Validation testing demonstrated that no adverse effects have been introduced by these differences and that the device performs as intended.

From the results of nonclinical testing described, Medela Inc. concludes that the Sonata breast pump is as safe and as effective as the predicate device and supports a determination of substantial equivalence.
