The Argyle™ Polyurethane Umbilical Vessel Catheter is intended for short-term vascular access via umbilical vessels in neonatal patients.

The Argyle™ Polyurethane Umbilical Vessel Catheter is a single-lumen catheter made of a polyurethane catheter tube which is insert molded to a polypropylene hub. The insertion tip of the catheter has been heat melted to form a smooth, rounded tip to reduce tissue trauma upon insertion. Encapsulated within the catheter walls are three barium sulfate strips spaced 120° apart, which run the length of the catheter. Placement of the device is facilitated by depth markings, which are printed on the catheter at 1 cm intervals, beginning at 5 cm from the insertion tip and continuing to 25 cm from the tip. Catheter placement must be confirmed by x-ray. The Argyle Polyurethane Umbilical Vessel Catheter will continue to be available in three sizes: 2.5 Fr.; 3.5 Fr.; and 5 Fr. Each device will continue to be packaged in a Tyvek pouch; 10 pouches are packaged in a carton. The Argyle Polyurethane Umbilical Vessel Catheter does not contain DEHP and is Ethylene Oxide sterilized. The product and packaging is not made of natural rubber latex.

The provided document is a 510(k) summary for a medical device called the Argyle™ Polyurethane Umbilical Vessel Catheter. It describes the device, its intended use, and states that it has undergone non-clinical performance testing to demonstrate substantial equivalence to a predicate device.

Crucially, this document notes that no clinical testing was performed for the determination of substantial equivalence (Section 8. Clinical Data).

Therefore, I cannot provide information on acceptance criteria and a study that proves the device meets those criteria from this document. The device's approval was based on non-clinical performance data (laboratory testing) demonstrating that the modified device continues to meet product specifications and is substantially equivalent to an existing device.

The document states:

• "Laboratory testing was completed to support substantial equivalence between the modified device and the current device. The modified device was evaluated to show compliance to the standards requirements as well as performance characteristics related to the modification of the device. The results of the testing show that the modified device continues to meet the requirements of the product specifications and supports the determination of substantial equivalence." (Section 7. Non-Clinical Performance Data)
• "No clinical testing was performed for the determination of substantial equivalence." (Section 8. Clinical Data)

Without clinical data, the concept of "acceptance criteria" and "device performance" in the context of clinical studies, human readers, ground truth established by experts, etc., as requested in your prompt, does not apply to this specific submission. The non-clinical performance data would involve engineering tests (e.g., material strength, fluid flow, biocompatibility) against predetermined specifications, but these are not equivalent to the clinical study parameters you've asked for.
