The Steripath® Micro Blood Collection System is a system to draw blood for in vitro diagnostic testing.

The Steripath® Micro Blood Collection System is indicated for use as a blood collection system that diverts and sequesters the initial specimen prior to collection of a subsequent test sample to reduce the frequency of blood culture contamination when contaminants are present in the initial blood cultures drawn with standard procedure without manual diversion.

Additionally, components of the system may be used for infusion following sample collection after discomection of the Initial Specimen Diversion Device® (ISDD®).

The device, Steripath® Micro Blood Collection System, is a system to draw blood for in vitro diagnostic testing. The purpose of this submission is to expand the product line to include inlet components with the BD Venipuncture® UltraTouch™ Push Button Needle, outlet components with a transfer adapter, and universal models with no inlet component.

The Steripath® Micro Blood Collection System is indicated for use as a blood collection system that diverts and sequesters the initial specimen prior to collection of a subsequent test sample to reduce the frequency of blood culture contamination when contaminants are present in the initial blood sample compared to blood cultures drawn with standard procedure without manual diversion.

The device sequesters and diverts 0.5 - 1.0 mL of the initial specimen of blood (potentially contaminated) into a diversion chamber. Once diversion is complete, a subsequent blood sample flows through a second pathway within the device and is collected either directly into a culture bottle (not provided by Magnolia Medical Technologies), or into a syringe that is used to inoculate culture bottles. Additionally, components of the system may be used for infusion after disconnection of the Initial Specimen Diversion Device® (ISDD®).

The Steripath® Micro Blood Collection System, needle configurations, for the subject device are manufactured using non-sterile BD UltraTouch® needles, which are equivalent to the commercially available BD UltraTouch® Push Button™ Blood Collection Set (K212724), except for the sterilization step. The Steripath® Micro Blood Collection System and UltraTouch® needles have the same intended use. Incorporation of the needle with the ISDD® functions on the same technological characteristics and principles of operation with the difference that the subject device leverages the Initial Specimen Diversion Technology® (ISDT) and mechanically sequesters the initial specimen of blood. Inclusion of this technology does not raise any added questions of safety or effectiveness.

The different configurations of the Steripath® Micro Blood Collection System are made available by using different combinations of the inlet and outlet accessories. Proposed configurations are listed in Table 5.1.

The provided text describes a medical device, the Steripath® Micro Blood Collection System, and its 510(k) premarket notification for substantial equivalence to a predicate device. The information details the device's characteristics and various types of testing performed to demonstrate its safety and effectiveness.

Here's an analysis of the acceptance criteria and the study information as requested:

1. Table of Acceptance Criteria and Reported Device Performance

2. Sample Size Used for the Test Set and Data Provenance

The provided text does not explicitly state the sample sizes used for the individual performance tests (sequestration, vacuum, diversion volume, etc.). It describes the types of tests performed (e.g., Sterilization, Aging/Shelf-Life, Biocompatibility, Packaging Integrity, and Performance Testing) and states that "all design verification and validation activities were performed."

The data provenance is not specified in terms of country of origin or whether it was retrospective or prospective data. The testing appears to be primarily laboratory-based engineering and performance verification testing rather than large-scale clinical studies.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

This information is not provided in the text. The type of testing described (e.g., sterilization, biocompatibility, mechanical performance) typically relies on established standards and laboratory protocols rather than human expert interpretation for "ground truth" in the way a diagnostic imaging study would.

4. Adjudication Method for the Test Set

This information is not applicable or not provided. Since the testing focuses on objective mechanical and biological properties against established standards, an adjudication method for conflicting expert opinions is not relevant in the context of the described tests.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size

No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done based on the provided text. The submission focuses on device characteristics and performance verification for substantial equivalence, not comparative effectiveness of human readers with or without AI assistance.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

No, this device is a physical medical device (blood collection system), not an AI algorithm. Therefore, "standalone" algorithm performance is not applicable.

7. The Type of Ground Truth Used

The ground truth used for the device's performance is based on established industry standards and engineering specifications for medical devices. For example:

• Sterilization: Standards like ISO 11137-1.
• Aging/Shelf-Life: Standards like ASTM F1980-16.
• Biocompatibility: Standards like ISO 10993-1.
• Packaging: Standards like ASTM D4169-16.
• Functional requirements (e.g., diversion volume, vacuum performance) are based on the device's design specifications.

8. The Sample Size for the Training Set

This device is not an AI/ML algorithm that requires a training set. Therefore, this information is not applicable.

9. How the Ground Truth for the Training Set Was Established

This device is not an AI/ML algorithm. Therefore, this information is not applicable.
