Dear Caitlin Liang:

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: The Center for Devices and Radiological Health (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

# Device Description

21 CFR 807.92(a)(4)

The Paruu Wearable Breast Pump is a powered breast pump intended to be used by lactating women to express and collect milk from their breast in home healthcare environment. The breast pump stimulates lactation and extracts milk from the breasts by creating a seal around the nipple and applying and releasing suction to the breast. The breast milk is collected in a milk collector. The device consists of a pump motor (main unit), milk collection set (flange, diaphragm, duckbill valve, milk collector, flange cover) and accessories (flange insert, charging cable). The milk collection set and flange insert can be purchased separately.

The device uses a diaphragm-type vacuum pump driven by a microprocessor. The microprocessor provides control over vacuum pressure and cycle speed. The user interface consists of buttons allowing the user to switch between

modes and control the vacuum pressure levels, and LED display that providing information on current mode, level, timer and battery status.

The device includes 23 different models, and based on their technological characteristics, are divided into two broad categories – P16 series consisting of models P16, P16-A, P16-B, P16-C, P16-D, and P20 series consisting of models P20, P9, P10, P10 PRO, P21, P22, P23, P24, P25, P26, P27, P28, P29, P30, P20-A, P20-B, P20-C, P20-D. The models within each series vary in terms of their external color. All device models include 4 working modes (Stimulation, Expression, Two-in-one and Dual frequency for P16 Series and Stimulation, Expression, Lactation, and Traction for P20 Series) and 12 suction levels for each mode.

To prevent milk from flowing into the vacuum system, the milk collection set includes a diaphragm that physically separates the milk-contacting pathway from the vacuum system. The motor unit operates on 3.7V rechargeable lithium battery. The rechargeable battery can be charged from the external power adapter (not included with the device) through the provided charging cable. All milk contacting components of the device are compliant with 21 CFR 177.

The subject and predicate device have similar Indications for Use and the same intended use (i.e., for the collection of breast milk from the breasts of lactating women). The subject and predicate devices have similar technological features, including wearable operation, power supply, and user interface. However, as shown in the table above, there are technological differences between the subject and predicate device, including different overall vacuum/cycle specifications and available suction levels in each mode. The different technological characteristics of the subject device, as compared to the predicate device, do not raise different questions of safety and effectiveness.
