The device description and performance studies focus on vacuum measurement, recording, and basic status indicators (lights). There is no mention of AI, ML, or any algorithms that learn or adapt from data.
No
The device is solely for measurement and recording purposes, providing data related to vacuum-assisted delivery. It does not exert any direct therapeutic action or influence clinical outcomes.
No
The device measures and records data related to vacuum-assisted delivery, such as vacuum, number and duration of pulls, and pop-offs. While it provides data, its primary function is measurement and monitoring during a procedure, not diagnosing a condition or disease.
No
The device description explicitly states it is a "small, battery powered single-use vacuum measuring device" and describes physical components like LEDs and electrical cables, indicating it is a hardware device with embedded software.
Based on the provided information, the VacuLink is not an In Vitro Diagnostic (IVD) device.
Here's why:
- Intended Use: The VacuLink is intended for "obstetric use in the measurement and recording of data related to vacuum-assisted delivery". This involves monitoring a physiological parameter (vacuum applied to the fetal head) during a medical procedure performed on a living patient.
- Device Description: The device measures vacuum applied to the fetal head and connects to maternal/fetal monitors. This is a direct measurement of a physical force applied during a delivery, not an analysis of biological samples (like blood, urine, tissue, etc.) which is the hallmark of IVD devices.
- Anatomical Site: The device is used in relation to the "Fetal head," which is part of a living organism.
- Lack of Biological Sample Analysis: There is no mention of the VacuLink analyzing any biological samples.
IVD devices are specifically designed to examine specimens derived from the human body (such as blood, tissue, urine, etc.) to provide information for the diagnosis, monitoring, or treatment of diseases or conditions. The VacuLink does not perform this function. It is a monitoring device used during a medical procedure.

Device Description
The VacuLink is a small, battery powered single-use vacuum measuring device. It is connected in-line to the vacuum chamber of commercial handheld vacuum extractors (e.g., Mityvac & Kiwi PalmPump). As a redundant gauge to pressure gauges on those devices, it electronically measures the vacuum applied to the fetal head during a vacuum assisted delivery. It connects to the vacuum channel of the maternal/fetal monitor (i.e. HP, Corometrics and Spacelabs) via electrical cable. The vacuum value is numerically displayed in centimeters of mercury (cm Hg). The vacuum value is also recorded from the uterine activity channel of the maternal/fetal monitor and it is permanently stored in the hospital database. The information may also be displayed on a video monitor as well.
The VacuLink incorporates a light sequence of red, yellow, and green. When the VacuLink is initially connected to the maternal/fetal monitor, all three lights will flash in sequence as a quick test of the internal components. At the successful completion of the test, the green LED illuminates until the VacuLink is disconnected from the maternal/fetal monitor. A flashing yellow LED illuminates when the battery voltage is low and the VacuLink should be replaced. If the VacuLink was used previously and is reconnected, the red LED illuminates indicating the VacuLink is no longer operational.

Summary of Performance Studies
Performance testing of VacuLink has been conducted in three main phases:
- Initial bench testing to compare VacuLink technology to certified reference gauges and other gauges in use at community hospitals.
- Initial clinical phase (feasibility study)
- Secondary bench testing on the current configuration of the VacuLink device
Performance testing of VacuLink as well as the reusable handheld vacuum devices reveals that the VacuLink is as accurate as the claimed accuracy of the comparable vacuum gauges. In actual clinical situations, because of the lack of calibration of the comparable vacuum gauges, the VacuLink was more accurate by a factor of 10. Electrical safety and EMC testing was also performed to demonstrate conformance to applicable medical standards. Software validation and sterilization process information have also been provided.

(a)
Identification. A fetal vacuum extractor is a device used to facilitate delivery. The device enables traction to be applied to the fetal head (in the birth canal) by means of a suction cup attached to the scalp and is powered by an external vacuum source. This generic type of device may include the cup, hosing, vacuum source, and vacuum control.(b)
