This document is a 510(k) summary for the T-Port HP Infusion Port, which is an implantable device used to provide repeated access to the vascular system. It is important to note that this document is a 510(k) summary, not a detailed study report. Therefore, it focuses on demonstrating substantial equivalence to a predicate device rather than presenting a comprehensive study with detailed acceptance criteria and performance data for a new AI or diagnostic device.

Based on the provided text, the device is a physical medical device (infusion port and catheter system), not an AI or imaging diagnostic device. As such, the information requested in your prompt (e.g., sample size for training/test sets, expert qualifications, MRMC study, standalone algorithm performance, AI vs. human improvement) are not applicable to this type of device and are not found in the document.

The document describes the device, its intended use, and its equivalence to a previously cleared device (K071993). The "acceptance criteria" here are tied to demonstrating substantial equivalence for regulatory clearance, primarily through material biocompatibility and functional specifications that match or are equivalent to the predicate device.

Here's an attempt to address your points based on the available information, with many points being "Not Applicable":

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

• Max infusion rate: 2 ml/sec with 22G non-coring needle.
• Max pressure: 300 psi. |
  | Mechanical Integrity: Withstands specified infusion pressures without failure. | (Implicit in meeting power injection specifications and substantial equivalence to predicate) |
  | Sterilization: Sterilized according to established practices. | Manufactured and sterilized at the same facilities as the predicate device (K071993). |
  | Labeling/Instructions for Use (IFU): Provides clear and accurate information for safe use. | Provides necessary accessories (e.g., guide wire, dilator, Huber needle, IFU) and outlines intended use and power injection parameters. |

2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)

• Not Applicable. This is a physical medical device. The "test set" in the context of a 510(k) for such a device refers to bench testing, material testing, and potentially some animal studies (though not detailed here) comparing it to the predicate, rather than a clinical data set for an AI algorithm.
  • No specific sample sizes for clinical data are mentioned, as the focus is on device specifications and equivalence.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)

• Not Applicable. Ground truth, in the context of expert consensus, is not relevant to demonstrating substantial equivalence for a physical medical device like an infusion port. The "ground truth" for this device would be its physical and mechanical properties, material safety, and functionality, verified through engineering and biocompatibility testing.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

• Not Applicable. Adjudication methods are relevant for subjective assessments, typically in diagnostic imaging or clinical trials. This document pertains to the regulatory clearance of a physical device based on objective specifications and equivalence.

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. MRMC studies are used for evaluating diagnostic performance, especially with AI assistance. This device is an infusion port, not a diagnostic tool where "human readers" would be involved in interpreting its output.

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

• Not Applicable. The T-Port HP Infusion Port is a physical device, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

• For physical device characteristics: The "ground truth" is established through engineering specifications, material standards, biocompatibility testing results (e.g., ISO standards), and verified manufacturing processes.
• For performance claims (e.g., power injection rates): The ground truth would be volumetric and pressure measurements performed during bench testing, ensuring the device can safely handle the stated flow rates and pressures without failure.

8. The sample size for the training set

• Not Applicable. This is not an AI/machine learning device. No "training set" in that sense exists.

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

• Not Applicable. As above, no training set is involved.

The provided 510(k) summary for the T-Port HP Infusion Port does not contain information about acceptance criteria or a study proving its performance against acceptance criteria in the manner typically described for AI/ML-based devices or complex diagnostic tools.

This document describes a medical device, specifically an implantable infusion port, and its substantial equivalence to previously marketed devices. The "performance" discussed relates to its physical characteristics and functionality, not to a diagnostic or predictive algorithm.

Therefore, I cannot populate the requested table and answer many of the questions as the information is not present in the provided text.

However, I can extract information related to the device's technical specifications and how its "performance" (in terms of physical capabilities) is established through comparison to predicate devices.

Explanation of Missing Information:

• Acceptance Criteria & Reported Device Performance (Table): This type of information is typically for devices that perform a measurement or make a diagnostic determination, where criteria like sensitivity, specificity, accuracy, or specific thresholds for a measurement are set. For an infusion port, "performance" is more about structural integrity, flow rates, and biocompatibility, which are verified through engineering tests and material comparisons, not typically reported in terms of specific "acceptance criteria" and "reported device performance" in a 510(k) summary like this. The document states its capabilities (e.g., maximum infusion rates, pressure) but doesn't frame them as acceptance criteria for a study.
• Sample Size, Ground Truth, Adjudication, MRMC, Standalone Study, Training Set Info: These are all concepts relevant to studies evaluating the performance of algorithms, diagnostic devices, or AI/ML systems. They are not applicable to the clearance of an implantable infusion port which relies on demonstrating substantial equivalence to predicate devices through comparisons of material, design, and intended use, often supported by bench testing and sometimes animal studies (though not detailed here beyond biocompatibility).

What the document does provide regarding "performance" and "studies":

The document primarily focuses on demonstrating substantial equivalence to predicate devices. This is the "study" in this context.

Description of Device Capabilities (which could be considered performance specifications):

• Maximum Recommended Infusion Rate:
  • 19 or 20 gauge non-coring needle: 5 ml/sec
  • 22 gauge non-coring needle: 2 ml/sec
• Maximum Pressure: Not to exceed 300 psi.
• Biocompatibility: Materials are used in legally marketed devices under comparable conditions of use.

Nature of the "Study" (Demonstration of Substantial Equivalence):

The "study" or justification for clearance is based on comparing the T-Port HP Infusion Port to two predicate devices:

1. pfm Medical, Inc Manufacturer: MedComp Name: Jet Port Plus Catheter System (Cleared under K000125) - This is for the basic functionality as an implantable infusion port.
2. Power Injectable Implantable Infusion Port (Cleared under K070003) - This is for the addition of power injection capability.

The document states: "The port and catheter are manufactured and sterilized at the same manufacturing and sterilization facilities as the predicate device cleared under K000125. The addition of power injection capability is comparable to the currently marketed Power Injectable Implantable Infusion Port cleared under K070003."

This implicitly means that the performance specifications (flow rates, pressure limits) for power injection are comparable to the K070003 predicate device, and the general port functionality (repeated access, material, sterilization) is comparable to the K000125 predicate device.

Therefore, I cannot fill out the requested template in full, but can summarize the device capabilities and the basis of its clearance.
