The Gabriel 3-way EnFit valve is a three-way closed system valve with three ports for control of fluid flow (nutrition, medication and water) between devices with EnFit connectors and catheter tip syringe. It can be used in pediatric, adult and elderly patients, for up to 7 days.
The Gabriel 3-way EnFit Valve is a three-way stopcock valve that is intended to control fluid flow between enteral devices (feeding tubes and feeding lines) with EnFit compatible connectors in a closed system fashion that reduces the need for frequent connection of the EnFit ports. It has one male EnFit port, one female EnFit port and one catheter tip port. The catheter tip port can be used for flushing and administration of medication using a catheter tip syringe. The male EnFit port is provided with a tethered cap and the catheter tip port is provided with a tethered cap. The ability to use a catheter tip syringe for flushing and administration of medicine in health care facilities that do not carry EnFit syringes, may facilitate adoption of feeding tubes and feeding lines with EnFit connectors.
The provided text describes a medical device, the "Gabriel 3-Way EnFit Valve," and its 510(k) submission to the FDA. However, this document does not contain information about an AI/ML-enabled device or its acceptance criteria and study results for such a device.
The document primarily focuses on demonstrating substantial equivalence of a physical medical device (a 3-way valve) to a predicate device based on design, materials, intended use, and bench testing for mechanical performance and biocompatibility.
Therefore, I cannot answer the questions related to AI/ML acceptance criteria, performance studies (like MRMC or standalone performance), ground truth establishment, sample sizes for training/test sets, or expert qualifications/adjudication. These concepts are not discussed in the provided text.
The closest information provided is the summary of bench testing for the physical valve. Below is a table of the acceptance criteria (stated as "PASS" for each test) and the reported device performance from the document.

| Leakage by Pressure Decay Test | No leakage under pressure decay conditions | PASS |
| Positive Pressure Liquid Leakage Test | No leakage under positive pressure liquid conditions | PASS |
| Stress Cracking Test | Resistant to stress cracking | PASS |
| Resistance to Separation from Axial Load Test | Resists separation from axial load | PASS |
| Resistance to Separation from Unscrewing Test | Resists separation from unscrewing | PASS |
| Thread Overriding Resistance Test | Resistant to thread overriding | PASS |
| Disconnection by Unscrewing Test | Resists disconnection by unscrewing | PASS |
| Flexure modulus | Above 700 Mpa | PASS |
