Intended Use

The SKOUT system is a software device designed to detect potential colorectal polyps in real time during colonoscopy examinations. It is indicated as a computer-aided detection tool providing colorectal polyps location information to assist qualified and trained gastroenterologists in identifying potential colorectal polyps during colonoscopy examinations in adult patients undergoing colorectal cancer screening or surveillance. The SKOUT system is only intended to assist the gastroenterologist in identifying suspected colorectal polyps and the gastroenterologist is responsible for reviewing SKOUT suspected polyp areas and confirming the presence or absence of a polyp based on their own medical judgment. SKOUT is not intended to replace a full patient evaluation, nor is it intended to be relied upon to make a primary interpretation of endoscopic procedures, medical diagnosis, or recommendations of treatment/course of action for patients. SKOUT is indicated for white light colonoscopy only.

Device Story

SKOUT system is a software-based computer-aided detection (CADe) device for real-time analysis of high-definition endoscopic video during colonoscopy. It processes video input to identify potential colorectal polyps; outputs visual markers (blue rectangular outlines) superimposed on the endoscopic monitor. Used in clinical settings by gastroenterologists; system pauses detection when surgical tools are detected or lighting is inadequate to prevent obstruction. Includes a GUI with status indicators (active, tool present, or error). The device assists clinicians in polyp identification; however, the clinician retains responsibility for final diagnosis and clinical decision-making. Benefits include potential improvement in polyp detection rates during screening or surveillance.

Clinical Evidence

No clinical data presented. Substantial equivalence supported by software verification and validation, electrical safety/EMC testing (IEC 60601-1, IEC 60601-1-2, IEC 60601-2-18), and human factors validation.

Technological Characteristics

Software-based CADe system; single-piece hardware architecture. Interfaces with endoscopes (Olympus EVIS EXERA III, FUJI EC760 series). Powered by hospital mains. Features real-time video processing with AI-based detection algorithm. GUI provides visual status indicators and polyp bounding boxes. Complies with IEC 60601-1, IEC 60601-1-2, and IEC 60601-2-18 standards.

Indications for Use

Indicated for adult patients undergoing colorectal cancer screening or surveillance colonoscopy. Assists trained gastroenterologists in identifying potential colorectal polyps in real time during white light colonoscopy.

The SKOUT system is intended to aid gastroenterologists with the detection of potential colorectal polyps during colonoscopy by providing an informational visual aid on the endoscopic monitor using trained software that processes the endoscopic video in real time. Users will primarily interact with the SKOUT system by observing the software display, including the polyp detection box and device status indicator signal. #### Polyp Detection Notification The SKOUT system has a main graphical user interface (GUI) feature of the polyp detection notification. The polyp detection notification is a two-dimensional blue rectanqular outline generated around any suspected polyps on the endoscopic video feed. If there is no polyp detected, the bounding box does not appear. SKOUT® system pauses polyp detection when an endoscopic tools are detected in the video feed to ensure that the bounding box does not hinder any surgical procedure, biopsy, or resection or this may also occur when lighting conditions are deemed to be inadequate. {4}------------------------------------------------ The polyp detection notification enables users to: - Detect potential colorectal polyps during colonoscopy examinations in adult patients undergoing a . colorectal cancer screeninq or surveillance procedure. - Utilize a tool that provides additional information for endoscopic observation. ● ### Device Status Indicator The SKOUT system has an additional GUI feature that notifies users of the current device status (active or error): - a two-dimensional green box with letter (S) when the device is powered on and actively processing ● video. - o a two-dimensional grav box with letter (S) when a surgical tool is present. - a red (X) with an error message: when there is an error with the video processing function of the ● SKOUT system, the green box will be replaced with a red X and error message to indicate an error has occurred. ### Intended Use / Indications for Use The SKOUT system is a software device designed to detect potential colorectal polyps in real time during colonoscopy examinations. It is indicated as a computer-aided detection tool providing colorectal polyps location information to assist qualified and trained gastroenterologists in identifying potential colorectal polyps during colonoscopy examinations in adult patients undergoing colorectal cancer screening or surveillance. The SKOUT system is only intended to assist the aastroenterologist in identifying suspected colorectal polyps and the gastroenterologist is responsible for reviewing SKOUT suspected polyp areas and confirming the presence or absence of a polyp based on their own medical judgment. SKOUT is not intended to replace a full patient evaluation, nor is it intended to be relied upon to make a primary interpretation of endoscopic procedures, medical diagnosis, or recommendations of treatment/course of action for patients. SKOUT is indicated for white light colonoscopy only. # Design Changes Hardware architecture changes: The multi piece tethered system of the predicate to a single box containing all of the components.
