## 6. Device Description

The Compact Wearable Pump is a battery-powered breast pump which consists of the following components: pump body, breast flange, flange insert, diaphragm, manifold disk, collection cup, charging cord, and carrying bag. The subject device is capable of single pumping (using both packaged pumps independently). It is provided non-sterile and can be re-used by a single user. It does not incorporate off-theshelf (OTS) software or wireless technology/mobile app software functionality. The subject device cannot be operated while plugged into AC power.

The Compact Wearable Pump is designed to work in a user's bra. The main body includes a press-button user interface, pump body, and LED indicator lights. The user interface allows the user to switch from stimulation to expression mode and control the vacuum levels within those modes. Stimulation mode consists of 8 vacuum levels and fixed cycle speeds when used. Expression mode includes 8 vacuum levels with three different cycle speed configurations that vary duration between suction and let down for further customization by the user.

{4}------------------------------------------------

The Compact Wearable Pump is capable of providing vacuum levels from 36-159 mmHg with cycling rates of 1.67-3.04 cycles per second in stimulation mode and vacuum levels from 78-280 mmHg with cycling rates from 0.53-1.99 cycles per second dependent on which expression mode is used. The Compact Wearable Pump is charged with a 5 V DC USB type C adaptor and powered by a 3.8 V, 1300mAh internal rechargeable lithium-ion battery.

The breast pump expresses breast milk by creating a seal around the nipple using a flange and applying and releasing suction to the milk is collected in a milk collection container, which can be used for storage. To prevent milk from flowing into the vacuum system, a backflow protection membrane physically separates the milk-contacting pathway from the vacuum system.

All other components (i.e., motor unit) of the subject device are not in contact with the breast. All milk contacting components are compliant with 21 CFR 174-179.

# 7. Indications for Use

The Compact Wearable Pump is intended to express and collect breastmilk from lactating women for the purpose of feeding collected breastmilk to a baby. The Compact Wearable Pump is intended for a single user.

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

The subject and predicate devices have similar technological features, including expression mode options, control mechanism, backflow protection, and device indicators. However, as shown in the table above, there are technological differences between the subject and predicate device, including different vacuum and cycle specifications, power supply, wear configurations, and vacuum levels. The different technological characteristics of the subject device, as compared to the predicate device, do not raise different questions of safety and effectiveness.
