This document describes the premarket notification for the "PowerLoc™ Max Power Injectable Infusion Set" and "SafeStep™ Huber Needle Set". The study presented focuses on demonstrating substantial equivalence to a predicate device (K171735) through performance testing, rather than a standalone clinical study to establish new acceptance criteria. Therefore, much of the requested information regarding clinical studies, expert-established ground truth, and training data is not applicable in this context.

Here's a breakdown of the available and applicable information:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria for each test are implied by the "All testing passed the predetermined acceptance criteria" statement. Specific quantitative acceptance criteria or detailed performance results are not provided in this summary. Instead, the document lists the type of test conducted and the standard it references, indicating compliance.

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

• Sample Size: The document does not specify the exact sample sizes used for each individual performance test. It broadly states "All testing passed the predetermined acceptance criteria."
• Data Provenance: The studies were conducted "by or for Bard Access Systems (BD)". The data is presumably from laboratory testing, not patient data (retrospective or prospective), given the nature of the device and the tests performed. The country of origin for the data is not specified, but the applicant's address is in Salt Lake City, Utah, USA.

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

This information is not applicable. The device's substantial equivalence was established through engineering and performance testing against recognized standards, not through clinical trials requiring expert-established ground truth on patient data.

4. Adjudication Method for the Test Set

This information is not applicable, as no clinical study with human observers or adjudication committees was performed.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done, If So, What was the Effect Size of How Much Human Readers Improve with AI vs. Without AI Assistance

This is not applicable. This is a medical device (infusion set and Huber needle set), not an AI-powered diagnostic or assistive tool.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done

This is not applicable. This is a physical medical device, not an algorithm.

7. The Type of Ground Truth Used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" for the performance tests would be the established requirements and limits defined by the referenced ISO standards, USP standards, and internal protocols for a device of this type. For example, for "Assembly Burst," the ground truth is that the device must withstand a certain pressure without bursting, as defined by ISO 10555-1.

This document is a 510(k) Premarket Notification from the FDA regarding the PowerLoc® MAX Power-Injectable Infusion Set and SafeStep® Huber Needle Set. It establishes substantial equivalence to existing predicate devices, indicating that no new clinical study was required to prove safety and effectiveness for a new medical device. Instead, the submission focuses on demonstrating that the new packaging configurations and additional kit components of the subject devices do not alter their fundamental safety and performance characteristics compared to the previously cleared predicate devices.

Therefore, the typical acceptance criteria and study design for proving the performance of a novel AI-powered medical device are not applicable in this context. This submission is for a conventional medical device (infusion sets and needles) and relies on bench testing, material comparisons, and risk management rather than clinical performance studies with AI.

However, I can extract information related to the acceptance criteria for this specific submission, which pertains to the device's substantial equivalence and safety/performance after changes, rather than a de novo AI device.

Here's a breakdown of the relevant information from the document:
