Intended Use
The Elvie Stride is a powered breast pump to be used by lactating women to express and collect milk from their breasts. The Elvie Stride is intended for a single user.
Device Description
Elvie Stride is an electric breast pump that is intended for lactating women to express and collect breast milk. It is intended for a single user. It may be operated as a single or double pumping system. Elvie Stride has adopted the in-bra aesthetic. It is designed to work in the user's nursing bra and has a rechargeable battery so it can be used hands-free without any external power cords. The pump is located off the body and the milk collection bottle is located on the breast. It expresses milk by applying negative pressure to the nipple so that expressed milk may collect in the milk collection bottle. It can be controlled through the physical interface on the pump or through a mobile companion app. Elvie Stride consists of 15 components: Hub, Breast Shield, Cup Front, Diaphragm Seal, Valve, Stopper, Tubing, Tube Splitter, Hub Connector, Cover, Cup Seal, Cap, Cap Seal, Clip and USB Charging Cable. All components are reusable and may be manually cleaned or placed on the top shelf of a dish washer.
More Information

No
The summary does not mention AI, ML, or any related concepts like image processing, training sets, or performance metrics typically associated with AI/ML devices. The performance studies focus on standard medical device testing (biocompatibility, electrical safety, software validation, and basic performance metrics like vacuum pressure).

No.

A therapeutic device is typically used for the treatment or prevention of a medical condition. A breast pump, while assisting with a biological process, is not classified as a therapeutic device. It is designed to express and collect milk, not to treat a disease or medical condition.

No

The device is a breast pump, used to express and collect milk, and does not perform any diagnostic function.

No

The device description explicitly lists 15 physical components (Hub, Breast Shield, Cup Front, etc.) and describes it as an "electric breast pump," indicating it is a hardware device with accompanying software.

Based on the provided information, the Elvie Stride is not an IVD (In Vitro Diagnostic) device.

Here's why:

  • Intended Use: The intended use is to "express and collect milk from their breasts" for lactating women. This is a physical process involving the body, not a test performed on a sample taken from the body to diagnose a condition.
  • Device Description: The description details a mechanical pump that applies negative pressure to the nipple to collect milk. This is a physical intervention, not a diagnostic test.
  • Lack of Diagnostic Testing: There is no mention of analyzing biological samples (like milk) for diagnostic purposes. The performance studies focus on the mechanical and electrical functionality of the pump, not on the analysis of milk composition or the diagnosis of any condition.
  • Anatomical Site: The device interacts with the breasts, which is a physical interaction for milk expression, not a site for collecting a sample for in vitro analysis.

IVD devices are specifically designed to perform tests on samples (like blood, urine, tissue, etc.) taken from the human body to provide information for the diagnosis, monitoring, or treatment of diseases or conditions. The Elvie Stride does not fit this description.
