The Winx Sleep Therapy System is indicated for home use in the treatment of obstructive sleep apnea (OSA) in adults.

The Winx Sleep Therapy System consists of four (4) main components and two (2) sizing methods. The components are: a small electronic bedside console, a soft polymer mouthpiece, a flexible polymer tube that connects the mouthpiece to the console, and a physicians' software application (Winx Data Management Software) that allows clinicians to download usage data from the console and generate patient usage reports. The sizing methods include: a sizing template and an iPhone sizing application (Winx Mouthpiece Sizing Application). The mouthpiece is an intraoral device that is worn during sleep. The system is designed to increase airway patency and decrease airway obstruction.

The provided text is a 510(k) summary for the Winx Sleep Therapy System, which is an intraoral device for obstructive sleep apnea. It describes the device, its intended use, and states that it is substantially equivalent to a predicate device based on performance data from bench testing.

However, the document does not contain the following information:

• A table of acceptance criteria and reported device performance. The document only states that "Results of bench testing demonstrate that the Winx Sleep Therapy System is safe and effective for its intended use and substantially equivalent to the predicate." It does not provide specific performance metrics or acceptance thresholds.
• Details about any clinical study, including sample sizes, data provenance, ground truth establishment, expert qualifications, adjudication methods, or MRMC studies. The approval explicitly states it's based on "bench testing" and not clinical trial data.
• Sample sizes for training sets. As there's no mention of a clinical study or an AI/algorithm-only performance evaluation, this information is not applicable and not present.

Therefore, many of your specific questions cannot be answered from the provided text. The document refers to "Performance Data" but then immediately states that "Results of bench testing demonstrate..." This indicates that the evaluation for substantial equivalence was primarily based on non-clinical (bench) testing, not on human clinical trials that would involve the collection of efficacy data against specific acceptance criteria.

Summary of available information vs. requested information:

1. A table of acceptance criteria and the reported device performance: Not provided. The document states "Results of bench testing demonstrate that the Winx Sleep Therapy System is safe and effective for its intended use and substantially equivalent to the predicate" but does not quantify performance or acceptance criteria.
2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): Not applicable/Not provided. The evaluation was based on bench testing, not a clinical test set.
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): Not applicable/Not provided. No clinical test set.
4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable/Not provided. No clinical test set.
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/Not provided. This device is for sleep therapy, not an AI diagnostic imaging tool; therefore, MRMC studies are not relevant in this context and not mentioned.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable/Not provided. No mention of an AI algorithm being evaluated.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not applicable/Not provided. The evaluation was based on a comparison to a predicate device via bench testing, not clinical outcomes or expert ground truth.
8. The sample size for the training set: Not applicable/Not provided. No AI algorithm is mentioned, and therefore no training set.
9. How the ground truth for the training set was established: Not applicable/Not provided. No AI algorithm and no training set.
