No
The device description focuses on mechanical components and functions (hollow tube, balloon, irrigation, vacuum, handle rotator) and the performance studies are related to physical properties and simulated use, with no mention of data processing, algorithms, or learning.
No
The device is described as an overtube used with an endoscope to facilitate intubation, change of endoscopes, and treatment, but its primary function as described in the "Device Description" is providing stabilization and shape maintenance, not directly providing therapy.
No
This device is designed to facilitate the intubation, endoscope changes, and treatment within the GI tract. It is an accessory to an endoscope, which might be used for diagnostic purposes, but the device itself does not perform any diagnostic function (e.g., imaging, signal analysis to identify disease).
No
The device description clearly outlines a physical medical device consisting of a hollow tube, balloon, irrigation line, vacuum line, and handle rotator. It requires connection to external hardware like a vacuum source and a balloon controller unit.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections. They are used to provide information for diagnosis, monitoring, or screening.
- Device Function: The Pathfinder Endoscope Overtube with Balloon is a medical device used within the gastrointestinal tract to facilitate endoscopic procedures. It is a tool used during a medical procedure, not a test performed on a sample outside the body.
- Intended Use: The intended use clearly states it's for facilitating intubation, changing endoscopes, and treatment in the gastrointestinal tract. This is an in-vivo (within the living body) application.
- Device Description: The description details a physical device used to manipulate and stabilize an endoscope within the body. It doesn't mention any components or processes related to analyzing biological samples.
- Performance Studies: The performance studies focus on the functional aspects of the device itself (lubricity, insufflation, navigation, rigidization, balloon performance, biocompatibility), not on the accuracy or reliability of a diagnostic test.
Therefore, the Pathfinder Endoscope Overtube with Balloon is a medical device used for procedural support within the body, not an in vitro diagnostic device.

Device Description
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.

(a)
Identification. An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments. This section does not apply to endoscopes that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.(b)

1.11 Conclusions
Like the predicate originally cleared by the FDA, the modified Pathfinder Endoscope Overtube with Balloon Device has been shown to be safe through performance testing. Design changes made to the device do not raise any questions of safety or effectiveness. Verification and validation data support substantial equivalence of the modified Pathfinder Endoscope Overtube with Balloon Device to the legally marketed predicate device.
