The Pathfinder Endoscope Overtube with Balloon is intended to be used with an endoscope to facilitate intubation, change of endoscopes, and treatment in the gastrointestinal (GI) tract in adult patients (22 years of age and older).

The Pathfinder Endoscope Overtube with Balloon device consists of a hollow tube with a balloon at the distal end for use over a flexible gastrointestinal endoscope. The purpose of the balloon is to contact the lumen walls to provide stabilization to the distal end of the overtube within the GI tract. The endoscope is inserted through the proximal end of the device and comes out the distal end. The free space between the overtube and the endoscope is lubricated with water through the irrigation line by connecting to the irrigation/water Luer (female Luer lock fitting) and injecting water. The vacuum line is connected to free space within the device and is completely contained. A source of vacuum must be connected to the barb fitting per the diagram below for the overtube to transition between the flexible and rigid conditions. The balloon line is connected to an extrusion within the device that creates an air pathway from handle to the balloon. An inflation device must be connected to the Luer (male Luer lock fitting) to inflate and/or deflate the balloon. The handle rotator has two positions. The first position connects the device to atmosphere (vent) to stay in the flexible condition. The second position connects the device to a source of vacuum to transition to the rigid condition. When transitioned to the rigid condition, the device maintains its shape at the time of rigidization, allowing the endoscope to advance or withdraw relative to the overtube with minimal disturbance to surrounding anatomy. Balloon inflation and deflation are actuated and controlled by an existing balloon controller unit within the endoscopy suite. The device must be connected to the balloon controller to transition into the inflated and deflated condition.

The provided text does not contain information about a study that proves a device meets acceptance criteria related to AI/algorithm performance.

The document is a 510(k) Premarket Notification from the FDA to Neptune Medical, Inc. for their "Pathfinder Endoscope Overtube with Balloon Device." It describes the device, its intended use, comparison to predicate devices, and summaries of functional and performance bench testing, and biocompatibility testing. It explicitly states:

• "No clinical testing was applicable to this submission."
• The entire submission focuses on a physical medical device, not an AI or algorithm.

Therefore, I cannot fulfill your request to describe the acceptance criteria and study for an AI-powered device's performance, as the provided text pertains to a traditional medical device not involving AI.
