The T-Port HP Infusion Port is indicated for patient therapies requiring repeated access to the vascular system. The port system can be used for infusion of medications, IV fluids, parenteral nutrition solutions, blood products and for the withdrawal of blood samples.
When used with a power injectable needle, the T-Port HP Infusion Port is indicated for power injection of contrast media. For power injection of contrast media, the maximum recommended infusion rate is 5 ml/sec with a 19G or 20G non-coring power injectable needle or 2 ml/sec with a 22G non-coring power injectable needle.
The T-Port HP Infusion Port is an implantable device designed to provide repeated access to the vascular system without the trauma associated with multiple vena puncture. The system consists of a self-sealing injection port and a delivery catheter for the receipt and delivery of medications to the selected body site. The T-Port HP Infusion Port is offered with the polyurethane catheter either preattached by the manufacturer or attachable for application by the inserting physician. The port can be anchored with sutures in the port pocket for secure seating. The catheter lock provides securement of the catheter to the port. Introduction of solution into the implanted port and catheter system is through a non-coring needle.
The base of the port has the letters "CT" to signify that it can be used for power injection on contrast agents. The serial number is laser etched into the base of the port. The suture holes may contain clear silicone to prevent tissue in growth to the suture holes.
Power injection of contrast media, can be safely administered with a 19 or 20 gauge power injectable infusion non-corning needle at a maximum recommended infusion rate of 5 ml/sec or a 22 gauge power injectable non-coring needle at a maximum recommended infusion rate of 2 ml/sec. Maximum pressure should not exceed 300 psi.
The T-Port HP Infusion Port is packaged with the necessary accessories to facilitate catheter insertion.
The port and catheter are manufactured and sterilized at the same manufacturing and sterilization facilities as the predicate device cleared under K071993. .

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
| Acceptance Criteria (Inferred from substantial equivalence to predicate) | Reported Device Performance (Inferred from specifications and equivalence) |
|---|---|
| Biocompatibility: Materials used are safe for implantation. | Materials are the same as those used in legally marketed devices under comparable conditions of use. |
| Functional Equivalence: Provides repeated vascular access for infusion and blood withdrawal. | Functions as an implantable port and catheter system for repeated vascular access. |
| Power Injection Capability: Supports specified infusion rates and pressures for contrast media. | - Max infusion rate: 5 ml/sec with 19G/20G non-coring needle. |
- 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.
§ 880.5965 Subcutaneous, implanted, intravascular infusion port and catheter.
(a)
Identification. A subcutaneous, implanted, intravascular infusion port and catheter is a device that consists of a subcutaneous, implanted reservoir that connects to a long-term intravascular catheter. The device allows for repeated access to the vascular system for the infusion of fluids and medications and the sampling of blood. The device consists of a portal body with a resealable septum and outlet made of metal, plastic, or combination of these materials and a long-term intravascular catheter is either preattached to the port or attached to the port at the time of device placement. The device is available in various profiles and sizes and can be of a single or multiple lumen design.(b)
