Intended Use

The Endobronchial Tube is used to isolate the left or right lung of a patient for surgery, one lung ventilation or one lung anesthesia.

Device Description

The Endobronchial Tube is made of Polyvinylchloride and is available in sizes 26fr to 41fr. They are designated as double lumen tube with 2 cuffs and separate 15mm connectors for isolating and ventilating one lung during surgical procedures. The tubes contain an x-ray opaque line that runs through the tube making them detectable by x-ray. Environments of use: Hospital-OR and ICU

AI/ML Overview

The provided text describes the 510(k) submission for the "Endobronchial Tube" by Henan Tuoren Medical Device Co., Ltd. and its substantial equivalence to a predicate device (Well LEAD Endobronchial Tubes, K092886). The evaluation primarily relies on non-clinical testing (bench testing and biocompatibility assessments) to demonstrate that the proposed device meets established standards and performs comparably to the predicate.

Here's an analysis of the requested information based on the provided text:

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

The document provides a detailed table of performance testing for the Endobronchial Tube.

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

The document does not specify the exact sample size for the mechanical performance tests, biocompatibility tests, or endotoxin tests. It mentions "non-clinical testing was performed" and provides "Test result" for each criterion. The data provenance is not explicitly stated in terms of country of origin for the testing, but the manufacturer is Henan Tuoren Medical Device Co., Ltd, China. The testing described is clearly prospective for the device being submitted, as it was performed to demonstrate compliance with standards.

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)

This product is a medical device (Endobronchial Tube, Class II), not an AI or imaging diagnostic device. Therefore, the concept of "experts establishing ground truth for a test set" in the context of image interpretation or clinical diagnosis is not applicable here. The "ground truth" for this device's performance is established by adherence to engineering and biocompatibility standards and quantified through objective physical and chemical measurements.

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

Not applicable. This is not a study involving human interpretation or subjective adjudication. The tests involve objective measurements against predefined criteria in recognized standards (e.g., ISO).

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 not an AI diagnostic device. No MRMC study was performed or required.

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

Not applicable. This is not an algorithm or AI device. The performance is assessed based on the physical properties and biological compatibility of the device itself.

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

The "ground truth" for this device's performance assessment is primarily defined by:

  • Engineering Standards: Specific requirements and limits outlined in international standards like ISO 5361, ISO 594/1, ISO 8836, and ISO 5356-1.
  • Biocompatibility Standards: Criteria for no toxicity, sensitization, or irritation as per ISO 10993 series.
  • Safety Standards: Endotoxin limits as per USP.

These standards provide objective, measurable criteria which serve as the ground truth against which the device's performance is evaluated.

8. The sample size for the training set

Not applicable. This is a physical medical device, not a machine learning model. There is no "training set" in the context of data for an algorithm.

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

Not applicable. As there is no training set, there is no ground truth established for it. The standards mentioned in point 7 serve as the universally accepted benchmarks for this type of device.

8. Product Performance Testing

All testing that is required by the required standards has been performed. Non-clinical testing was performed and included standards such as ISO 5361 and ISO 10993-1. The Endobronchial Tube have been found to fall within the required limits of the testing. The test results can be found in both the Biocompatibility (Section16) and the Performance Testing_Bench (Section19) of this submission. Therefore we have concluded that the Endobronchial Tube are substantially equivalent.

A brief summary of tests relied upon to demonstrate substantial equivalence to the predicate can be found in the table below:
