The Duploject® is intended for use in the simultaneous delivery of two non-homogenous fluids or solutions onto a surgical site. The Duploject® is equipped with a syringe holder, which assures controlled, accurate dispensing, and a needle holder, which allows the contents of the syringes to mix prior to dispensing.

Device Description

The Duploject® is a single-use, disposable syringe, which is used in the application of two nonhomogenous fluids or solutions onto a surgical site. The Duploject® consists of two disposable syringes and withdrawal needles for reconstitution of the solutions. It also contains the following components for use in the simultaneous application of the two solutions: a clip, with a common plunger, is used to join the two identical disposable syringes together and ensures that equal volumes of the two components are fed through a common joining piece and mixed prior to dispensing. Three extra application needles and one extra joining piece are included in the package to use as replacements, if needed. The Duploject® is sterile and non-pyrogenic.

AI/ML Overview

This looks like a 510(k) premarket notification for a medical device called Duploject®. However, it does not contain the specific information you requested regarding acceptance criteria or the study proving the device meets those criteria.

The provided text focuses on:

Device Description: What the Duploject® is and how it works.
Intended Use: The purpose of the device.
Comparison to Predicate Devices: How the Duploject® is similar to other legally marketed devices (Duoflo Dispenser, RMI Dual Fluid Irrigating Syringe, Surgical Sealant Dispenser). This comparison table is a key part of establishing substantial equivalence, which is the basis for 510(k) clearance.
FDA Clearance Letter: Official communication from the FDA stating that the device is substantially equivalent and can be marketed.

While the table labeled "Comparison of device characteristics to predicate" does list "Delivery Accuracy," it only states "The slide bar on the syringe holder ensures delivery of equal amounts of the contents of the syringes." This is a feature description, not a quantitative acceptance criterion or a report of measured performance. There is no study data presented to "prove" this beyond the assertion.

Therefore, I cannot provide the requested information from the given text alone. The document is a regulatory submission for substantial equivalence based on comparison to predicate devices, not a detailed performance study report.

Dear Dr. West:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions The general controls provisions of the Act of the Act. include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major requlations affecting your device can be found in the Code of Federal Requlations, Title 21, Parts 800 to 895. ਸ substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Requlation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory In addition, FDA may publish further announcements action. concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531
