The provided text is a 510(k) Premarket Notification from the FDA regarding a medical device called the MiniSpacer Dual Spray MDI Adapter. This document is a regulatory submission for a device, which typically describes an engineering verification and validation study rather than a clinical study for AI software.
Therefore, the requested information regarding acceptance criteria and performance against those criteria, especially details such as sample size for test sets, data provenance, expert ground truth adjudication, MRMC studies, standalone algorithm performance, and training set information (which are all highly relevant to AI/ML device evaluations), is not present in this document. The document primarily focuses on demonstrating substantial equivalence to predicate devices based on design, materials, intended use, and general performance, rather than AI-specific metrics.
However, I can extract the following relevant information based on the request, reinterpreting some categories in the context of a non-AI medical device submission:
Acceptance Criteria and Device Performance
- Product: MiniSpacer® 1024, 1025, 1543 and 1024A, 1025A, 1543A Dual Spray MDI Adapter
- Study Type: This document describes a premarket notification (510(k)) to establish substantial equivalence to predicate devices, not a clinical trial or AI performance study. The "study" here refers to the engineering verification and biocompatibility assessment for the physical device.
| Acceptance Criterion (Standard or Predicate Equivalence) | Reported Device Performance |
|---|---|

| Legacy SBC. | biological safety for the intended device population compared to |

| intended device population, despite a change in the body resin. |
Additional Requested Information (as applicable to this document):
-
Sample sizes used for the test set and data provenance:
- Test Set Sample Size: Not specified in the document. The testing described appears to be bench testing for material and functional equivalence.
- Data Provenance: Not explicitly stated, but the toxicological assessment and comparisons against predicate devices would be based on internal testing and regulatory standards. It's a regulatory submission, not a clinical trial, so "country of origin" of data or "retrospective/prospective" does not apply in the typical sense for patient data.
-
Number of experts used to establish the ground truth for the test set and their qualifications:
- Not applicable in the context of this device. Ground truth is established through engineering specifications, material standards, and regulatory requirements (e.g., biocompatibility testing interpreted by toxicologists) rather than expert consensus on medical images or patient outcomes.
-
Adjudication method for the test set:
- Not applicable. This is not a study requiring adjudication of expert interpretations. Compliance is determined by engineering testing and regulatory assessment.
-
If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and its effect size:
- No, an MRMC study was not done. This device is a physical medical component (an actuator for MDI medication), not an AI diagnostic or treatment planning system that would involve human readers interpreting data.
-
If a standalone (i.e., algorithm only without human-in-the-loop performance) was done:
- Not applicable. This device does not involve an algorithm or AI component.
-
The type of ground truth used:
- For material and functional performance, the "ground truth" is defined by established engineering specifications, performance standards, mechanical testing results, and toxicological assessment standards. For regulatory approval, the ultimate "ground truth" is established by demonstrating substantial equivalence to legally marketed predicate devices through comparative analysis and testing.
-
The sample size for the training set:
- Not applicable. This device does not involve machine learning or a training set.
-
How the ground truth for the training set was established:
- Not applicable, as there is no training set for an AI/ML algorithm.

Dear Amy Fowler:
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 (the 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 available 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}------------------------------------------------
Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).
Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30. Design controls; 21 CFR 820.90. Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).
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 Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-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 Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).

COMPARISON OF TECHNOLOGICAL CHARACTERISTICS:
SUMMARY OF PERFORMANCE TESTING:
Biocompatibility: There are no direct patient contacting parts to this device. The patient contact is External Communicating, Tissue, Long Term (> 30 d). A thorough toxicological assessment has been written on the data from the biocompatibility tests. The assessment supports substantial equivalence and biological safety for the intended device population.
No animal or clinical testing was necessary for evaluation of substantial equivalence.
SUBSTANTIAL EQUIVALENCE CONCLUSION:
Based upon the above comparisons, the subject device is substantially equivalent to the predicate devices. The only difference is the modification to the resin for the body, and the toxicological testing and risk assessment support that the subject device is substantially equivalent to the predicate(s). The information submitted demonstrates that the device is as safe and effective as the legally marketed devices.
