The iNAP One Sleep Therapy System is indicated for home use in the treatment of obstructive sleep apnea (OSA) in adults in whom positive airway pressure is not the preferred treatment choice.

The iNAP One Sleep Therapy System consists of six (6) main components. The components include a console (Model R07-A), a saliva container, a saliva absorbent (iNAP DryPad), a flexible polymer tubing (iNAP Tubing Set), soft polymer oral interfaces (iNAP Oral Interface), a Muffler (Optional) and a software application for mobile devices (iNAP Lab+). One additional accessory set (102C) is included, which is a combination of the iNAP Oral Interface and iNAP Tubing Set. The function of iNAP One Sleep Therapy System (Console Model: R07-A) is to develop a negative pressure gradient in user's oral cavity which can be adjusted between -20 to -90 mmHg (-27 to -122 cmH2O) via the App (iNAP Lab+) to achieve or maintain proper vacuum pressure for users.

Here's a breakdown of the acceptance criteria and study information based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The acceptance criteria for the iNAP One Sleep Therapy System are primarily focused on its pressure setting range, accuracy, and clinical performance in treating Obstructive Sleep Apnea (OSA). The reported device performance is based on the clinical study described.

• 72.2% (13 subjects) achieved a successful response (treated AHI 50% from baseline and treated AHI 5), baseline AHI, and post-treatment AHI after 28 days of therapy. While PSG is the gold standard for diagnosing OSA and establishing AHI, the document does not specify the number of experts (e.g., sleep specialists, polysomnographic technologists) used to interpret these PSG studies or their specific qualifications.

4. Adjudication Method for the Test Set

The document does not describe any specific adjudication method (e.g., 2+1, 3+1) for establishing the ground truth from the PSG results. It can be inferred that the PSG interpretations likely followed standard clinical protocols for sleep studies, which inherently involve expert interpretation.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done, and the effect size of how much human readers improve with AI vs without AI assistance

There is no mention of a Multi-Reader Multi-Case (MRMC) comparative effectiveness study or any evaluation of human readers improving with AI assistance. The device is a "Sleep Therapy System" that generates negative pressure for OSA treatment, not an AI-assisted diagnostic tool for human readers.

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

The device itself is a physical therapy system, not an algorithm. Therefore, a "standalone algorithm only" performance evaluation, as might be done for an AI diagnostic tool, is not applicable in this context. The clinical study evaluates the performance of the device in use by patients.

7. The Type of Ground Truth Used

The ground truth for evaluating the device's efficacy was established using Polysomnogram (PSG), which is considered the gold standard for diagnosing and quantifying Obstructive Sleep Apnea (OSA). The key metric used was the Apnea-Hypopnea Index (AHI).

8. The Sample Size for the Training Set

The document does not mention the existence of a "training set" in the context of machine learning. The clinical study described is an evaluation of the device's performance after its development, not a study to train an algorithm.

9. How the Ground Truth for the Training Set was Established

As no training set (in the machine learning sense) is mentioned, this question is not applicable. The clinical study serves to demonstrate the safety and effectiveness of the device itself.

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.

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

The Attune Sleep Apnea System consists of three (3) main components: a small electronic bedside console, a soft polymer mouthpiece, and a flexible polymer tube that connects the mouthpiece to the console. A mouthpiece holder is provided for mouthpiece storage and use during weekly system cleaning.

The mouthpiece is an intraoral device that is worn during sleep. The system is designed to increase airway patency and decrease airway obstruction.

Console: The console generates a gentle negative pressure, collects excess saliva, records patient use time, and monitors pressure. The console is provided with a power cord, which connects to a standard electrical outlet. An optional laboratory console is available for use in a sleep laboratory. The laboratory console includes wires that extend from the console. The wires connect to the sleep laboratory's polysomnography (PSG) system, allowing the sleep technicians to view the console's pressure on the same monitor as the other PSG channels.

Mouthpiece: The mouthpiece is provided in ten (10) discrete sizes. Sleep technicians use a bite wax to obtain an impression of each patient's teeth and a sizing template to determine the best mouthpiece size.

Tubing: The tubing connects to the console by screwing into the console base and to the mouthpiece with luer connectors.

Use: The patient connects the system and places the mouthpiece in his or her mouth. The mouthpiece is worn during sleep. The console generates a gentle, negative pressure, which is delivered through the mouthpiece into the oral cavity and holds the tongue and soft palate out of the airway.
