The PowerMidline™ Catheters are indicated for short term access to the peripheral venous system for selected intravenous therapies, blood sampling, and power injection of contrast may be used for any patient population with consideration given to adequacy of vascular anatomy and appropriateness of the procedure. The PowerMidline™ Catheters are suitable for use with power injectors.
The dual lumen PowerMidline™ catheters are a family of peripherally placed catheters made from radiopaque body-softening polyurethane materials. Each dual lumen PowerMidline™ catheter is designed with kink-resistant, reverse taper design. The dual lumen PowerMidline™ catheters are offered in a 4 F dual lumen (DL) and 5 F dual lumen (DL) configuration for reliable short term (less than 30 days) vascular access. These catheters are offered in 20 cm trimmable lengths. The dual lumen PowerMidline™ catheters are suitable for use with power injectors.
This document is a 510(k) summary for the PowerMidline Catheter (K162900) by Bard Access Systems, Inc. It describes the device, its intended use, indications for use, and a comparison to its predicate device (K153393). The document primarily focuses on demonstrating substantial equivalence to a previously cleared device, rather than defining and proving new acceptance criteria for an innovative device feature or algorithm.
Therefore, the requested information about acceptance criteria and a study proving a device-specific, newly established acceptance criteria cannot be fully extracted from this document in the way it's usually applied to a new AI/medical device. The document explicitly states: "The performance tests completed on the subject device were limited to those tests required to support a determination of substantial equivalence to the predicate device." and "when technological characteristics between the subject and predicate device were found to be identical, results of the performance testing conducted on the predicate device were applied to the subject device."
The "acceptance criteria" here are essentially "meets the performance requirements of the predicate device" or "meets the requirements of the specified ISO/FDA guidance documents."
However, I can extract the types of performance tests conducted and the standards/guidances used, which implicitly define what was considered acceptable performance.
1. Table of Acceptance Criteria and Reported Device Performance
Instead of explicit numerical acceptance criteria, the document states that the device "met all predetermined acceptance criteria" derived from various performance tests. The "reported device performance" is the confirmation that these implicit criteria were met, leading to a determination of substantial equivalence.
| Acceptance Criteria (Implicit) | Reported Device Performance |
|---|---|
| Priming Volume: The priming volume of the dual lumen PowerMidline™ Catheter should be measured and reported in accordance with FDA Guidance on Premarket Notification [510(k)] Submission for Short-Term and Long-Term Intravascular Catheters, March 16, 1995, and BAS Internal Protocols/Procedures. (Implicit criterion: The device must have a measured priming volume that is safe and acceptable for its intended use, comparable to similar devices if applicable). | "Test and Report Priming Volume" - Met (as implied by the statement "the subject device met all predetermined acceptance criteria"). Specific values are not provided in this summary. |

2. Sample Size Used for the Test Set and the Data Provenance
The document does not specify an exact "sample size" for the performance tests in terms of number of catheters tested for each criterion. It simply states that "performance tests completed on the subject device were limited to those tests required to support a determination of substantial equivalence."
- Sample Size: Not explicitly stated as a numerical count for each test. The tests were performed on "the subject device" which includes 4 F DL and 5 F DL configurations.
- Data Provenance: The tests were conducted internally by Bard Access Systems, Inc. ("BAS Internal Protocols/Procedures"). This implies the data is prospective in nature, generated specifically for this submission, rather than retrospective clinical data. The country of origin is implicitly the USA, where the manufacturer is located.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts
Not applicable in the context of this device. This is a physical medical device (catheter), and the "ground truth" for its performance is established through objective engineering and biological performance testing against recognized standards (ISO, FDA guidance). There is no "ground truth" derived from expert interpretation of data in the way one would for an AI diagnostic algorithm.
4. Adjudication Method for the Test Set
Not applicable. This concept is relevant for studies involving human interpretation or clinical outcomes where discrepancies need to be resolved. Performance testing of a physical device against standards does not typically involve adjudication in this sense. The acceptance relies on the measured performance meeting the predefined (or implicitly defined by the standard) thresholds.
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
Not applicable. This is a physical medical device (catheter), not an AI algorithm intended for interpretation by human readers. Therefore, an MRMC study and analysis of human reader improvement with AI assistance is not relevant.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
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 this device's performance is established by:
- Compliance with recognized international standards (e.g., ISO 10555-1:2013, ISO 10993-1:2009, BS EN ISO 14971:2012).
- Compliance with FDA Guidance documents (e.g., "Guidance on Premarket Notification [510(k)] Submission for Short-Term and Long-Term Intravascular Catheters, March 16, 1995").
- Internal protocols and procedures developed by the manufacturer, which would be designed to ensure the device meets its design specifications and is safe and effective for its intended use.
Essentially, the "ground truth" is adherence to established engineering, materials, and biological performance specifications and regulatory requirements.
8. The sample size for the training set
Not applicable. This is a physical device submission; there is no "training set" in the context of machine learning or AI models. The design and manufacturing processes are analogous to a training process, leading to the final device design.
9. How the ground truth for the training set was established
Not applicable. As there is no training set in the AI sense, there is no ground truth establishment for it. The development of the device's design (analogous to "training") is guided by medical necessity, engineering principles, material science, regulatory requirements, and feedback from previous predicate devices. The "ground truth" for the predicate device would have been its demonstrated safety and effectiveness in previous clearances.
