Device Description

The devices are breathing circuit filters used to filter the inhaled and/or the exhaled air of the patient against microbiological and particulate matter from the gases in the breathing circuit. They enclose a filter material in a housing that fits to standard breathing system connectors. Additionally, there are breathing system filters combined with a foam to function as HME (Heat and Moisture Exchangers) for passively humidifying the inspired air. The portfolio contains the following types of breathing circuit filters: - Filter CareStar Plus are electrostatic filters for use against contamination with microorganisms - . Filter SafeStar Plus are mechanical filters for use against contamination with microorganisms - Filter/HME TwinStar Plus are filters for use against contamination with microorganisms and for passive humidification of breathing gases

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 explicitly state the sample sizes used for each non-clinical test. It mentions that "The devices... have undergone extensive testing" but does not detail the number of units tested for each criterion. The data provenance is also not specified; however, given that the submitter is "Drägerwerk AG & Co. KGaA" based in "Lübeck, Germany" and they tested against international standards (ISO, ASTM, IEC), it is likely that the testing was conducted in a controlled laboratory environment, potentially in Germany or by a certified testing facility adhering to these standards. The testing appears to be prospective, specifically designed to verify the devices' adherence to the mentioned standards.

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

The document does not mention the use of experts to establish ground truth for the non-clinical test set. The validation relies on adherence to established international and national standards (e.g., ISO, ASTM, IEC) rather than expert consensus on a test set. This implies that the "ground truth" is defined by the objective metrics and methodologies outlined in these standards.

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

There is no mention of an adjudication method in the text for the non-clinical test set. Given the nature of the tests (physical and performance characteristics against standards), it's a pass/fail determination based on quantitative measurements against predefined criteria, not a subjective assessment requiring adjudication.

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

The document explicitly states "Summary of Clinical Testing N/A" (page 20). This indicates that no clinical studies, including MRMC comparative effectiveness studies involving human readers or AI assistance, were performed or submitted. The entire submission focuses on non-clinical performance and substantial equivalence based on technical characteristics and adherence to standards.

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

Since the devices are breathing circuit filters and not software or AI-powered devices, the concept of a "standalone (algorithm only)" performance study is not applicable. The device's performance is intrinsically mechanical and material-based, not algorithmic.

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

The ground truth for this submission is based on established international and national consensus standards (e.g., ISO 9360-1, ISO 5356-1, ISO 80369-7, IEC 60601-1, ISTA 3A, ISO 23328-1, ASTM F2101, ISO 10993, ISO 18562-1). The device's performance is measured against the quantitative requirements and methodologies specified within these standards.

8. The sample size for the training set

This question is not applicable. The document describes physical medical devices (filters), not machine learning or AI models that require a "training set."

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

This question is not applicable, as there is no training set for these devices.

Dear Luise Lang:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

{1}------------------------------------------------

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-

combination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to https://www.fda.gov/medical-device-safety/medical-device-reportingmdr-how-report-medical-device-problems.
