#### IV. Device Description
The ATMOS C 051 Thorax (317.0200.0) drainage system is a device for mobile, digital thoracic drainage. It is portable, mains-independent and has an electronic monitoring system with optical and acoustic display. The device takes medical effect as a system in combination with a secretion canister and a hose system. The system creates the (natural) vacuum in the pleural cavity by draining off air and secretion.
The ATMOS C 051 Thorax is equipped with a rechargeable battery. A charging unit which is located within the suction device guarantees the secure charging of the battery.
The hose system is rinsed with air at regular intervals to prevent the collection of debris in the hose. Bacterial and viral filters in the secretion canister and measuring hose prevent contaminated secretions from entering the device. The device is equipped with a disposable strap and a carrying handle. These enable mobility. A universal bracket or the standard rail bracket can be ordered separately as accessories.
The ATMOS C 051 Thorax is a reusable device delivered in non-sterile state. The secretion canister and hose systems are single-use devices and delivered sterile. All other accessories subject to this submission are reusable and delivered non-sterile.
#### V. Indications for Use
The ATMOS C 051 Thorax is indicated for aspiration and removal of surgical fluids, tissue, gases, bodily fluids, or infectious material from a patient's respiratory system after surgery. The general indication of the ATMOS C 051 Thorax is thoracic drainage.
#### VI. Indications for Use Comparison
The subject ATMOS C 051 Thorax and the predicate ATMOS S 201 Thorax are both devices for mobile, digital thoracic drainage. Both devices have the same indications for use - aspiration and removal of surgical fluids, tissue, gases, bodily fluids, or infectious material from a patient's respiratory system after surgery. The general indication is thoracic drainage.

Image /page/6/Picture/1 description: The image features the logo of ATMOS MedizinTechnik. The logo consists of the word "ATMOS" in a bold, sans-serif font, stacked above the words "MedizinTechnik" in a smaller, bolder font. The word "ATMOS" is encircled by a blue ring, giving the logo a clean and modern appearance. The overall design is simple and professional, reflecting the company's focus on medical technology.
#### VII. Technological Comparison
The ATMOS C 051 Thorax has the same technological characteristics regarding operation principle, use and type of accessories, vacuum control and maximum vacuum compared to the predicate device ATMOS S 201 Thorax.
The following differences exist:
- . Size and weight: The subject secretion canister has only 800 ml compared to 2 L of the predicate canister, and the subject device weighs only 1.16 kg compared to 3.27 kg of the predicate device.
- " Home use: Home care use is possible with the subject device but not for the predicate device.
- . Pump performance: Free flow rate is lower for the subject device (5 +/- 0.5 L/min) compared to the predicate device (18 +/- 2 L/min).
The completed verification and validation tests, as well as human factors validation and risk management activities, show that these differences do not raise new or different questions of safety and/or effectiveness.
#### VIII. Summary of Non-Clinical and/or Clinical Tests
Performance tests were carried out to ensure that the subject device functions as intended and meet design specifications. The following performance data were provided in support of substantial equivalence determination:
- . Electrical, Mechanical, and Thermal Safety
The ATMOS C 051 Thorax has been successfully tested for electrical, mechanical, and thermal safety in accordance with AAMI/ANSI and IEC 60601 standards and complies with IEC 60601-1, IEC 60601-1-2, and IEC 60601-4-2.
- l Software
The ATMOS C 051 Thorax contains software. The documentation level for the device software is considered to be "enhanced." Software validation activities were performed in accordance with the FDA guidance "Content of Premarket Submissions for Device Software Functions," issued on June 14, 2023. To fulfill the requirements with regard to cybersecurity, the FDA guidance document "Cybersecurity in Medical Devices: Quality System Considerations and Content of Premarket Submissions," issued on September 27, 2023, was followed.
- 트 Biocompatibility Testing

Image /page/7/Picture/1 description: The image shows the logo for ATMOS MedizinTechnik. The logo consists of the word "ATMOS" in blue, surrounded by a blue circle. Below the circle, the words "MedizinTechnik" are written in black.
A biological evaluation was performed according to ISO 10993-1 and followed the recommendations in the FDA guidance "Use of International Standard ISO 10993-1, "Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process," issued September 8, 2023, including Attachment G: Biocompatibility of Certain Devices in Contact with Intact Skin.
#### l Performance Bench Testing
The completed tests include tests with regard to design and performance, as well as human factors validation. Risk analysis was carried out based on acceptance criteria established in accordance with ISO 14971.
The following bench performance tests of ATMOS C 051 Thorax were performed with no unexpected results or significant deviations:
- -Maximum flow rate
- -Function and accuracy of flow display
- -Minimum to maximum vacuum
- Function, accuracy and control delay of vacuum display -
- -Battery operation at full power mode
- -Battery charge time
- -Over suction protection
- -Weight
- Alarm sound and noise level -
- -Length of hose system
### Human factors validation:
A usability engineering process has been performed in accordance with IEC 62366-1:2015+Cor1:2016+A1:2020, IEC 60601-1-6:2010+A1:2013+A2:2020, and FDA guidance document "Applying Human Factors and Usability Engineering to Medical Devices," issued on February 3, 2016. FDA draft guidance "Content of Human Factors Information in Medical Device Marketing Submission," issued on December 9, 2022, has been followed as well. The use-related risk analysis lists all identified risks associated with the use of the device. The human factors (HF) engineering report summarizes the conducted HF testing. The performed human factors validation shows that the use of the device is safe, especially with regard to the use by lay persons. The residual risks that

The logo is simple and modern, and the use of blue gives it a professional and trustworthy feel.
remain after HF validation testing for the ATMOS Thorax C 051 have been reviewed and determined to be acceptable.
A risk management process is routinely performed by ATMOS as part of the product development in accordance with ISO 14971:2019. The Risk Management Documentation specifies all identified risks and summarizes all conducted risk management activities. Risks specifically related to the home use of the subject device have been considered in the risk management. The benefit-risk analysis shows that the overall benefits of using the device outweigh the risks. The device is safe and effective for use in the intended patient population.
#### " Reprocessing, Sterility, and Shelf-Life
Required cleaning and disinfecting procedures for the ATMOS C 051 Thorax are described in the instructions for use. A sterile validation was performed for the secretion canister and hose systems. Sterilization was performed according to ISO 11135.
#### IX. Conclusion
The performance testing demonstrates that the ATMOS C 051 Thorax is as safe and effective as, and substantially equivalent to, the predicate device for the same intended use. Any differences between the subject and predicate devices do not raise new or different questions of safety and effectiveness.
