Dear Jenni Vescovo:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

The predicate device has not been subject to a design-related recall.

## 5.0 Device Description

Pump In Style Pro+ is a powered breast pump intended to be used in a home environment (or similar such as an office). It features 2-Phase Expression technology, which runs pumping in two phases (Stimulation and Expression) by applying a cyclic negative pressure to mimic a baby's natural nursing rhythm.

K253498
Page 2 of 6
K253498

Pump In Style Pro+ comprises a pump unit, which includes:
- User-adjustable controls: "On/Off" for powering on/off the device, "Let-down" for switching between pumping phases, and "Increase vacuum"/ "Decrease vacuum" for controlling vacuum intensity levels;
- a port for connection of the tubing that channels the vacuum;
- a port for connection of the power supply;
- an internal, non-replaceable, rechargeable lithium-ion battery providing users the option to power the breast pump without reliance on a wall-connection or external power source;
- a LED battery status indicator which informs users of available charge;
- a pump phase LED status indicator which informs users of the active pump phase;
- vacuum level LED indicators (total of 16, one for each vacuum level).

Pump In Style Pro+ is a double electric breast pump that can be used to extract breast milk from one breast at a time (i.e., single pumping) or from both breasts simultaneously (i.e., double pumping). A DC (direct current) motor is used to drive a membrane aggregate. This membrane aggregate creates the negative pressure (suction) required to extract the breast milk.

The materials of the milk-contacting components are compliant with 21 CFR 177 and 21 CFR 178.

## 6.0 Indications for Use

The Pump In Style Pro+ breast pump is a powered breast pump to be used by lactating women to express and collect milk from their breasts. The powered breast pump is intended for a single user. This breast pump is intended to be used in a home environment.

The indications for use of the subject and predicate device are similar, and both devices have the same intended use (i.e., for the collection of breast milk from the breasts of lactating women). The technological differences between the subject and

Page 4 of 6

K253498
Page 5 of 6
K253498

the predicate device are the number of suction levels, suction level vacuum range, user-interface, the rechargeable Li-ion battery, and replaceable/detachable components of the breast pump (patient-contacting components). These differences do not raise different questions of safety and effectiveness and can be evaluated through performance testing.

## 8.0 Summary of Non-Clinical Testing

The following data were provided to support the substantial equivalence determination:

### Electrical Safety:

Testing was conducted in accordance with ANSI AAMI ES60601-1:2005/(R)2012 & A1:2012 C1:2009/(R)2012 & A2:2010/(R)2012 (Cons. Text) [Incl. AMD2:2021], Medical electrical equipment - Part 1: General requirements for basic safety and essential performance (IEC 60601- 1:2005/AMD2:2020) and IEC 60601-1-11:2015 Medical electrical equipment – Part 1-11: 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

### Electromagnetic Compatibility:

Testing was conducted in accordance with IEC 60601-1-2:2014/AMD1:2020 Medical Electrical Equipment - Part 1-2: General Requirements For Basic Safety And Essential Performance - Collateral Standard: Electromagnetic Compatibility - Requirements And Tests

### Software/Firmware Verification and Validation:

Software verification and validation testing as recommended in the 2023 FDA Guidance Document "Content of Premarket Submissions for Device Software Functions."

### Biocompatibility Evaluation:

Biocompatibility testing was leveraged from the predicate device submission in accordance with 2023 FDA Guidance Document "Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process".

### Non-clinical Performance Testing:

Performance testing was conducted to show that the device meets its design requirements and performs as intended. The performance tests include:

- Vacuum level verification testing conducted at each vacuum level demonstrated that the devices meet vacuum and cycle speed specifications.
- Battery performance testing was conducted to demonstrate that the battery remains

Page 5 of 6

{9}

K253498
Page 6 of 6
K253498

functional during its stated battery use-life.
- Battery status indicator testing was conducted to demonstrate that the battery status indicator remains functional during its stated battery life.
- Backflow protection testing was conducted to verify liquid does not backflow into the pump motor unit.

## 9.0 Conclusion

The results of the performance testing described above demonstrate that Pump In Style Pro+ is as safe and effective as the predicate device and supports a determination of substantial equivalence.
