## Device Description:

The Pump In Style® Advanced breast pump and kit are used to express and collect milk 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. Pumping with the Pump In Style® Advanced breast pump can be performed on one breast (single pumping) or on both breasts at the same time (double pumping).

The Pump In Style® Advanced breast pump employs a control knob (potentiometer) for the user to adjust the vacuum levels. Two suction rhythms are pre-programmed with variable vacuum levels and cycle rates (pump speed). The powered breast pump is capable of providing vacuum levels from -50 to -240 mmHg with cycle rates up to 120 cycles per minute.

The device employs a gear-driven diaphragm-type vacuum pump, powered by a DC motor supervised by a microcontroller. The microcontroller drives the "H" bridge providing speed and directional control over the DC motor. The device is electrically powered from external batteries (AA batteries) or from an external direct plug-in AC power supply or from a vehicle lighter adapter. The device is provided non-sterile.

The Pump In Style® Advanced breast pump provides the following user features:

- . Rotary knob for user adjustment of vacuum level/cycles and on/off
- 2-Phase Expression® Technology designed to mimic a baby's natural nursing rhythm: ●
- o Stimulation Phase (phase 1): Suction pattern with fast cycles and low vacuum to start milk flowing
- o 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. .

#### Indications for Use:

The Pump In Style® Advanced breast pump is a powered breast pump to be used by lactating women to express and collect milk from their breast. The powered breast pump is intended for a single user.

Table 5.1 Comparison of Pump In Style® Advanced to Predicate Device

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

The subject and predicate devices have identical indications for use and the same intended use expressing milk from the breasts of lactating women. Although the current version of the Pump In Style® Advanced has the same fundamental technology and principles of operation as the previously cleared version, several modifications have been made to the subject device. The subject and predicate devices do not have identical technological characteristics because the current version utilizes a switching AC power supply (Input: 100-240, 50/60Hz, 0.7A; Output: 9VDC, 2A) rather than a linear power supply of the predicate device (Input:110-120 VAC, 60Hz18W; Output: 9Vdc, 1.0A). In addition, the subject device includes oval shaped breast shields which are manufactured with a different material compared to the round breast shields of the

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

predicate device. These differences between the subject and predicate devices do not raise different questions of safety or effectiveness.

#### SUMMARY OF NON-CLINICAL TESTS:

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

- Biocompatibility evaluation in accordance with ISO 10993-1:2009 Biological evaluation ● of medical devices -- Part 1: Evaluation and testing within a risk management process.
- Cytotoxicity testing per ISO 10993-5:2009 O
- Guinea Pig Maximization Sensitization testing perISO 10993-10:2010 O
- Irritation testing per ISO 10993-10:2010 O
- Electrical Safety testing in accordance with:
- AAMI / ANSI ES60601-1:2005/A1:2012, Medical Electrical Equipment: Part O 1: General Requirements.
- Electrical safety testing for use in home in accordance with IEC 60601-1 o 11:2015. General requirements for basic safety and essential performance --Collateral standard: Requirements for medical electrical equipment and medical electrical systems used in the home healthcare environment.
- Risk analysis in accordance with ISO 14971:2007 ●
- . Electromagnetic compatibility testing in accordance with IEC 60601-1-2:2014 Medical electrical equipment - Part 1-2: General requirements for basic safety and essential performance - Collateral Standard: Electromagnetic disturbances - Requirements and tests.
- Software Validation: The software/firmware verification and validation was provided in ● accordance with the FDA Guidance document, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices," dated May 11, 2005.
- . Bench performance testing was conducted with internal test protocols to determine the minimum and maximum vacuum levels of the pump, as well as cycle rate and overflow protection, as compared to its specifications. The specifications were met for vacuum levels, cycle rate and overflow protection. Battery use life testing was also conducted to demonstrate the subject device maintains its specifications throughout its use life. These results held under conditions of single and double pumping modes with varying power sources (e.g. AC/DC power, vehicle lighter adapter, external battery pack).

## Conclusion:

The subject and predicate devices have the same intended use and the technological differences do not raise different questions of safety or effectiveness. The performance data demonstrate the subject device is substantially equivalent to the predicate device.
