AI/ML Overview

This is a tricky request as the provided text doesn't describe a study to prove acceptance criteria for a device in the traditional sense of an AI/software device. The document is an FDA 510(k) clearance letter for two physical devices: "Potty Pal" and "Forever-Dry," which are enuresis alarms. The clearance is based on substantial equivalence to devices marketed before May 28, 1976, not on performance metrics from a specific study against acceptance criteria as one would expect for an AI algorithm.

Therefore, many of the requested fields cannot be directly answered from the provided text. I will explain where the information is missing or not applicable within the context of these documents.

Acceptance Criteria and Device Performance

Since this is a 510(k) clearance based on substantial equivalence for physical enuresis alarms, there aren't explicit, quantified "acceptance criteria" and "reported device performance" in the same way an AI algorithm might have. The "performance" is implicitly tied to the predicate devices and the functionality described.

Table of Acceptance Criteria and Reported Device Performance (as inferred from the context):

Acceptance Criteria (Inferred)	Reported Device Performance (Inferred)
Functional Equivalence: Device effectively functions as an enuresis alarm.	The device consists of "Training parts, which has sewn in mylar conductive strips. The strips are connected to an audible alarm." It is "Powered by a 9V battery," implying functionality similar to predicate enuresis alarms.
Intended Use: Device is suitable for its stated indications.	"Potty Pal: ...daytime enuresis alarm... to assist toddlers in toilet training." "Forever Dry: ...nighttime enuresis alarm to aid in solving a child's nighttime bedwetting problem." This aligns with the fundamental purpose of enuresis alarms.
Safety: Device operates without undue harm.	(Not explicitly stated in the provided text, but assumed under general regulatory requirements for medical devices).
Predicate Equivalence: Device is substantially equivalent to a legally marketed predicate device.	The FDA letter states: "we have determined the device is substantially equivalent... to devices marketed in interstate commerce prior to May 28, 1976." The product code 78 KPN for "Enuresis Alarm" indicates it falls into an established category.

Study Details (Based on available information and the nature of a 510(k) for these devices)

Sample size used for the test set and the data provenance:
- Sample Size: Not applicable. The provided documents describe a 510(k) clearance for physical devices based on substantial equivalence, not a testing study with a "test set" in the context of an AI algorithm. There is no mention of clinical data or performance testing in terms of patient sample sizes.
- Data Provenance: Not applicable for a test set. The determination is based on a comparison to predicate devices legally marketed prior to May 28, 1976, as well as the device's design description.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts:
- Not applicable. There was no "ground truth" established by experts for a "test set" in the context of these physical devices. The FDA's review process involves regulatory experts evaluating the submission against existing regulations and predicate devices.
Adjudication method for the test set:
- Not applicable. No "test set" or adjudication method described for performance evaluation.
If a multi-reader multi-case (MRMC) comparative effectiveness study was done:
- No. An MRMC study is relevant for evaluating human reader performance, often with or without AI assistance. This is a clearance for physical enuresis alarms, not an AI software.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:
- Not applicable. These are physical, non-AI devices.
The type of ground truth used:
- For the substantially equivalent determination, the "ground truth" is adherence to existing regulatory standards and the known performance characteristics of legally marketed predicate enuresis alarms. There's no specific "ground truth" in terms of pathology or clinical outcomes data described for this 510(k) submission. The devices' efficacy is implied by their classification and equivalence to established technologies.
The sample size for the training set:
- Not applicable. These are not AI/machine learning devices, so there is no concept of a "training set."
How the ground truth for the training set was established:
- Not applicable as there is no training set.

Summary: The provided documents pertain to an FDA 510(k) clearance for two physical enuresis alarm devices ("Potty Pal" and "Forever-Dry") based on substantial equivalence to predicate devices. This regulatory pathway does not typically involve the kind of detailed performance study with acceptance criteria, test/training sets, expert ground truth, or MRMC studies that would be associated with evaluating an AI algorithm. The clearance signifies that the FDA has determined the device is as safe and effective as a legally marketed predicate device.

Re: K971855 Potty Pal and Forever-Dry Dated: April 12, 1997 Received: May 20, 1997 Regulatory class: II 21 CFR §876.2040/Product code: 78 KPN

Dear Mr. Sheppard:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, subject to the general controls provisions of the Act. 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.

If your device is classified (see above) into either class II (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under Radiation Control provisions, or other Federal laws or regulations.

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in yitre diagnostic devices), please contact the Office of Compliance at (301) 594-4613. Additionally, for question and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR 807.97).
