No
The device description explicitly lists multiple hardware components including a housing, motor, valve, PCB, battery, flange, connector, diaphragm, valve, and bottle. While it uses embedded software and an optional smartphone app, it is fundamentally a hardware device with integrated software.
Based on the provided information, the Perifit Pump is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The intended use is to "express milk from lactating women in order to collect milk from their breasts." This is a physical process involving the body, not a test performed on samples taken from the body to diagnose a condition.
- Device Description: The description details a mechanical pump with electronic controls, designed to physically extract milk. It does not describe any components or processes related to analyzing biological samples.
- Performance Studies: The performance studies focus on the physical and electrical safety and functionality of the pump itself (biocompatibility, electrical safety, software validation, vacuum levels, battery life, etc.), not on the accuracy or reliability of a diagnostic test.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (like milk itself for diagnostic purposes), reagents, or any other elements typically associated with IVD devices.
In summary, the Perifit Pump is a medical device, specifically a breast pump, but it does not fit the definition of an In Vitro Diagnostic device.

Device Description
The Perifit Pump is an electrically powered wearable single breast pump consisting of the following key components: a housing ("hub") containing pump electronics (motor, valve, PCB, rechargeable battery and associated components), and detachable milk-contacting components: a silicone flange (breast shield), a plastic (polypropylene) connector, silicone diaphragm, a silicone duckbill valve, a plastic bottle. Accessories provided with the Perifit Pump include a screw-on container lid, a USB charging cable, and bra adjustment buckle. The Perifit pump is a closed-system breast pump.
The hub user interface allows the user to power the breast pump on and off, and to operate the breast pump in two modes (stimulation, expression) and to control the vacuum settings within these modes. Each mode consists of 8 vacuum levels, capable of providing suction from 30 to 285 mmHg, with cycle speeds ranging from 68 to 120 cycles per minute in stimulation mode and 28 to 80 cycles per minute in expression mode.
The Perifit Pump is powered by an internal rechargeable lithium-ion polymer battery (3.7V 1500mAh). The breast pump cannot be operated while it is being charged. The Perifit Pump operates on embedded software, and software updates by end-users are supported. The subject device is intended for use in a home healthcare environment.
An optional smartphone app may be used with the Perifit Pump. The app may be used to control the operation of the breast pump (select mode and vacuum level, start and stop pumping), save pumping session history and display the quantity (in ml) of milk in the bottle on the user's smartphone. Use of the app is not mandatory to operate the Perifit Pump.
The Perifit Pump is a closed-system breast pump with an anti-backflow diaphragm which physically separates the air-pumping system from the milk-flow system.

The subject device and predicate device have the same intended use. Both the subject and predicate devices work according to the same technological principle. Suction is applied, then released, to the user's nipple in order to stimulate milk expression from a lactating woman's breasts. The user can control the vacuum intensity and select between two suction modes offering faster and slower suction cycles. The milk expressed from the breasts is collected in a collection container that is self-contained within the user's bra. Both systems are closed-system breast pumps with an anti back-flow diaphraqm physically separating the air-pumping system from the milk-collecting system. The subject device (hub containing the pump electronics plus milk-contacting elements) is fully contained within the user's bra, while the predicate's milkcontacting elements are fully contained within the nursing bra and connected to the pump using external tubing. Despite the difference in configuration, both pumps operate in the same manner, using an anti-backflow diaphragm to physically separate the pumping system from the milk collection system.
Both the subject and predicate device have the option of being used in conjunction with a smartphone app. Use of this app is not mandatory for either device, and both the subject and predicate breast pumps can be operated using only the user control interface on the hub.
The Perifit Pump app also includes some additional features that are not available with the predicate (e.g., estimate of milk volume during pumping session, selecting between several suction patterns).
The technological differences between the Perifit Pump and the predicate device do not raise different questions of safety or effectiveness.
