A vascular access catheter used for, infusion and withdrawal of blood, blood products, and fluids, central venous blood pressure monitoring (CVP), acute hyperalimentation, continuous or intermittent drug infusion.

The Triple Lumen Central Venous consists of a three-lumen, silicone shaft and manifold hub. With three separate lumens, it is possible to infuse/withdraw several different medications simultaneously. The catheter will be available in 12.5 Fr. The catheter will be part of a set which contains a percutaneous entry needle, peel-away sheath, curved wire guide, introducer and Luer-slip syringe. This set will be supplied sterile, packaged in trays.

The provided text describes a 510(k) premarket notification for a Triple Lumen Central Venous Catheter. This type of regulatory submission focuses on demonstrating substantial equivalence to a predicate device, rather than proving a new device's efficacy through extensive clinical trials. Therefore, the information typically requested in your prompt regarding acceptance criteria, specific performance metrics against those criteria, and detailed study designs (like sample sizes for test/training sets, expert qualifications, adjudication methods, MRMC studies, and standalone performance) would generally not be found in such a document for this type of medical device.

The study described is more akin to verification and validation testing to ensure the device performs as intended and is safe, rather than a clinical effectiveness study.

Here's an analysis based on the information provided:

1. A table of acceptance criteria and the reported device performance:

• Note: The document states that the test results "provide reasonable assurance that the device has been designed and tested to assure conformance to the requirements for its use." However, it does not explicitly list the quantitative acceptance criteria for each test or the specific quantitative performance values achieved by the device. This level of detail is typically found in the full submission, not the summary.

2. Sample sized used for the test set and the data provenance:

• Sample Size for Test Set: Not specified in the provided text.
• Data Provenance: The tests are "Testing conducted on the Triple Lumen Central Venous Catheter," implying bench testing rather than clinical data from a specific geographical origin. It's likely prospective in the sense that the device was manufactured and then tested according to a plan, but it's not a prospective clinical trial.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

• This type of information is not applicable as the "tests" described are engineering and material performance tests (tensile, flow, leak, occlusion, biocompatibility), not diagnostic or interpretative tasks requiring expert consensus for ground truth.

4. Adjudication method for the test set:

• Not applicable for the type of engineering and material performance tests described. Adjudication typically applies to expert review of diagnostic images or clinical outcomes.

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:

• No, an MRMC comparative effectiveness study was not done. This device is a physical medical catheter, not an AI-powered diagnostic or assistive tool.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

• Not applicable. This pertains to AI algorithms, which this device is not. The "standalone" performance here would refer to the device's physical performance in isolation, which is what the "Test Data" section addresses.

7. The type of ground truth used:

• The "ground truth" for these tests would be established through scientific and engineering standards and specifications. For example:
  • Tensile: Material strength specifications (e.g., ISO standards for medical devices).
  • Flow: Fluid dynamics principles and medical requirements for infusion rates.
  • Leak/Pressure: Pressure holding capacity standards for catheters.
  • Catheter Occlusion: Functional criteria to ensure patency.
  • Biocompatibility: ISO 10993 standards for biological evaluation of medical devices.

8. The sample size for the training set:

• Not applicable. This typically refers to training data for AI/machine learning models. The development of this physical medical device would involve engineering design and iterative prototyping, not a "training set" in the AI sense.

9. How the ground truth for the training set was established:

• Not applicable. See point 8.
