CombiSet Hemodialysis Blood Tubing Set
The Blood Tubing Set is a sterile, single use, disposable indicated for use with a prescribed hemodialyzer. For use with a compatible hemodialyzer, as per the labeling.
The Blood Tubing Set is intended for acute and chronic hemodialysis therapy.
The Blood Tubing Set is intended to be used with Fresenius Medical Care 2008® Series K, K2 and T Hemodialysis Machines.
The CombiSet Bloodline is a single-use, ethylene oxide (EO) sterilized blood tubing set. The CombiSet Bloodline is part of the extracorporeal hemodialysis circuit. During hemodialysis, the extracorporeal circuit transports arterial blood from the patient's arterial access (e.g., fistula or catheter), through a hemodialyzer, and back to the patient's venous access.
This document describes the premarket notification (510(k)) for the CombiSet Hemodialysis Blood Tubing Set. It does NOT describe a study involving an AI device or algorithm. Therefore, I cannot provide the requested information about acceptance criteria, study details, sample sizes, expert involvement, or comparative effectiveness with AI.
The document focuses on the substantial equivalence of the CombiSet Hemodialysis Blood Tubing Set to a predicate device (CombiSet SMARTECH Hemodialysis Blood Tubing Sets, K201207) through various performance, sterilization, and biocompatibility tests.
Here's the relevant information about the non-AI device's performance testing:

| Labeling Content per FDA Guidance (Blood Tubing Set) and ISO 8638 | Verify the Instructions for Use, color-coded components, unit labels, shipping carton graphics, and case labels for the bloodline meet the requirements of ISO 8638:2010 and FDA Guidance. | Met criteria |
| Readability of Barcode with Human Readable Identification Codes | Demonstrate that the barcode information on the outer container labels and unit labels for the bloodlines is capable of being scanned. | Met criteria |

Note: The document explicitly states: "All testing met predetermined acceptance criteria."
2. Sample size used for the test set and the data provenance:
The document does not provide specific sample sizes (e.g., number of units tested) for each performance or biocompatibility test. It mentions that "samples" were tested.
- Data Provenance: The studies were conducted by Fresenius Medical Care Renal Therapies Group, LLC, likely internally or through contracted labs, as part of their 510(k) submission to the FDA. The country of origin for the data is not specified beyond being part of a US FDA submission. It is implicitly prospective testing of the manufactured device.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
This information is not applicable as the document describes performance testing of a physical medical device (blood tubing set), not an AI device requiring expert ground truth for classification or diagnosis.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set:
This information is not applicable as the document describes performance testing of a physical medical device. The results of the physical tests (e.g., pressure resistance, leak tests) are objective measurements.
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 document is for a physical medical device (blood tubing set), not an AI device. No human reader studies or AI assistance were involved.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
Not applicable. This document is for a physical medical device, not an AI device or algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
The "ground truth" for the device's performance is based on established engineering standards and regulatory requirements (e.g., ISO 8638:2010, ISO 80369-7:2016, AAMI/ANSI/ISO 10993-7:2008, ANSI/AAMI/ST72:2019, ISO 10993-1:2018, ASTM F1671-13). The device's ability to resist pressure, prevent leaks, sustain flow rates, and demonstrate biocompatibility according to these standards serves as the ground truth.
8. The sample size for the training set:
Not applicable. This document describes the testing of a physical medical device, not an AI device that requires a training set.
9. How the ground truth for the training set was established:
Not applicable. See point 8.
