The Thoraguard System is intended to be used for aspiration and removal of surgical fluids, tissue, gases, bodily fluids or infectious materials. The Thoraguard System is indicated for all situations where chest drains are applied - especially for thoracic drainage in the pleural and mediastinal cavity in situations such as pneumothorax, after cardiac or thoracic surgery (post-operative), thorax injury, pleural effusion, pleural empyema or other related conditions. The Thoraguard System is intended for use on patients in appropriate care settings.

Device Description

The Thoraguard Surgical Drainage System is an AC/DC powered suction pump designed for the aspiration and removal of surgical fluids, tissue, gases, bodily fluids or infectious materials. The Thoraguard System offers automated drainage functionality, acquisition and display of drainage information, and safety alarms associated with changes in patient output.

The Thoraguard System consists of the three sub-systems: the Thoraguard Control Module, a reusable electronic device for generating and regulating suction; the Thoraguard Drainage Kit, a disposable drainage canister and dual lumen drainage tubing set; and the Thoraguard Chest Tube Kit, a dual lumen drainage catheter with a passive valve and filter.

Similar to traditional chest drainage systems, the Thoraguard System drains accumulated blood and fluid through the chest tube using regulated suction. The control module facilitates this drainage automatically and works in conjunction with the drainage kit to function as a powered suction pump. The system may be used with any drainage catheter; when used with the Thoraguard Chest Tube Kit, the system provides automated clearance of clogs within the chest tube itself. During normal operation, the control module displays relevant system information via the touchscreen graphical user interface.

AI/ML Overview

The provided text is a 510(k) premarket notification summary for the Thoraguard System, which is a powered suction pump. This document describes the device, its intended use, and performance data supporting its substantial equivalence to a predicate device.

However, the provided text does not contain the specific details required to answer your request about acceptance criteria and a study proving the device meets those criteria.

Here's why and what information is missing:

Table of Acceptance Criteria and Reported Device Performance: This information is not explicitly presented in a table format, nor are specific quantitative acceptance criteria or detailed device performance metrics (e.g., specific suction rates, pressure ranges with thresholds) provided. The document states that "bench tests qualified its functionality, integrity and performance" and that "all testing requirements" and "all electrical safety and EMC testing requirements" were passed, but it doesn't give the specifics of those requirements or the exact outcomes against them.
Sample Size and Data Provenance for Test Set: Not mentioned.
Number of Experts and Qualifications for Ground Truth: Not applicable, as no clinical study involving expert assessment or ground truth establishment in this context is described. The performance data primarily refers to bench testing, biocompatibility testing, electrical safety, EMC, software verification, and usability testing.
Adjudication Method for Test Set: Not applicable.
MRMC Comparative Effectiveness Study: No multi-reader multi-case comparative effectiveness study is mentioned. This device is a medical pump, not an AI diagnostic tool that would typically involve human readers interpreting images.
Standalone (Algorithm Only) Performance: Not applicable, as this is a physical medical device (pump) with integrated software, not a standalone algorithm.
Type of Ground Truth Used: For the bench testing, the "ground truth" would be the engineering specifications and reference standards (e.g., ISO 10079-1:2015, EN 1617:1997). For biocompatibility, it refers to ISO 10993-1:2009. These are not "expert consensus, pathology, or outcomes data" in the typical sense applied to diagnostic AI.
Sample Size for Training Set: Not applicable. This is a hardware device with software, not a machine learning model that undergoes "training."
How Ground Truth for Training Set Was Established: Not applicable.

In summary, the document describes performance testing for a medical device (a pump), focusing on its physical and functional attributes against engineering standards, rather than a diagnostic AI system with expert-defined ground truth and clinical performance metrics.

Dear Evan Luxon:

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 (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 located 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.

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

7. Performance Data

The following performance data were provided in support of the substantial equivalence determination.

Performance Bench Testing

The Thoraquard System has been verified for its intended use by conducting a series of bench tests that qualified its functionality, integrity and performance. The testing performed included suction performance tests per ISO 10079-1:2015, catheter performance test per EN 1617:1997, and systemlevel verification testing.

Biocompatibility Testing

Biocompatibility for the Thoraguard chest tube has been assessed in accordance with ISO 10993-1:2009 Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management system.

Electrical Safety and Electromagnetic Compatibility (EMC)

The Thoraguard Surgical Drainage System has been evaluated for electrical safety and electromagnetic compatibility (emissions and immunity) and has passed all electrical safety and EMC testing requirements.

{5}------------------------------------------------

Software Verification and Validation Testing

Software verification and validation has been performed and the Thoraguard System has passed all testing requirements.

Usability Testing

Centese has performed usability validation of the Thoraguard System and has found the it to be safe and effective for the intended users, uses, and use environments.
