## Intended Use

The Avantis Medical Systems, Inc. Third Eye is indicated for use in the instrument channel of a conventional colonoscope to provide retrograde illumination and visualization of the colon for diagnostic purposes.

## Device Story

Third Eye Retroscope is an auxiliary endoscopy system used during colonoscopy. Device consists of a disposable Retroscope and Cap, and a reusable Video Processor. After a colonoscope reaches the cecum, the Retroscope is inserted through the instrument channel; it automatically bends 180 degrees into a 'J' shape upon exiting the distal tip. The system provides continuous retrograde (backward-looking) visualization of the colon during colonoscope withdrawal. The Video Processor interfaces with the Retroscope, processes video signals, and provides user controls for light intensity and picture settings. The physician views the retrograde image on a monitor alongside the standard colonoscope view. This dual-view approach improves the detection of polyps and adenomas compared to traditional colonoscopy alone. The device is intended for use in clinical settings by trained physicians.

## Clinical Evidence

Prospective, multi-center post-market study. Results demonstrated that retrograde viewing with the Third Eye significantly improved the detection of polyps and adenomas compared to traditional colonoscopy alone. Findings were statistically significant. Risks to patients were comparable to those reported in literature for traditional screening colonoscopies.

## Technological Characteristics

System includes a disposable Retroscope, Cap, and a Video Processor. Retroscope features a flexible design that assumes a 'J' shape upon deployment. Video Processor provides electrical interface, signal processing, and user-adjustable light/picture settings. Connectivity includes video output to a monitor. Sterilization is maintained via sterile barrier packaging. Software is used for image processing and user control adjustments.

## Regulatory 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.

procedure. After a colonoscope has been advanced to the cecurn, the Third Eye Retroscope is inserted through the instrument channel of the colonoscope. As the Third Eye Retroscope emerges from the distal tip of the instrument channel of the colonoscope, it automatically bends 180 degrees to form a "J" shape. The Third Eye then provides a continuous retrograde image of the colon throughout the process of withdrawal of the colonoscope.

The Third Eve Video Processor is a piece of electrical equipment that acts as an interface for the Third Eye Retroscope, the video output signals, and user input controls. The output video signals from the Video Processor are displayed on a monitor for viewing by the physician. Application software that runs on the Video Processor allows the user to adjust the light intensity and various picture settings of the Third Eve Retroscope image.

- Intended Use: e)
The Third Eye Retroscope is intended for use in the instrument channel of a conventional colonoscope to provide retrograde illumination and visualization of the colon for diagnostic purposes.

### Discussion of Substantial Equivalence to Predicate Device: f)

The Third Eye has been modified to a) accommodate additional conventional colonoscope models and brands, b) provide product enhancements, c) improve manufacturability, and d) update software. The modified device is substantially equivalent to the cleared predicate device in fundamental design materials, processes, sterile barrier packaging, and sterilization. All changes have been subjected to risk analysis and have been verified to meet current design specifications.

The IFU has been updated to a) add clinical data, b) clarify procedural directions based on the clinical experiences and c) expand the indications for use based on clinical data demonstrating that the Third Eye used with a traditional colonoscope improves detection of polyps and adenomas during colonoscopy as compared to the use of a colonoscope alone.

Differences between the modified Third Eye System and the predicate device have no impact on safety and effectiveness.

#### Scientific Technology g)

The Third Eye Retroscope® Auxiliary Endoscopy System includes the Retroscope, a Video Processor, Cap and accessories. Modifications made to the device and accessories did not change the fundamental scientific technology of the device. The testing described demonstrates that the differences in the device components and

accessories do not raise any new or unresolved issues for safety and efficacy.

## Summary of Supporting Non-Clinical Performance Data h)

Bench verification testing was conducted to verify that the modified device meets the design inputs and intended performance characteristics. Results demonstrate that modifications made to the Third Eve design performs as intended.

### Summary of Supporting Clinical Data i)

Results from a prospective, multi-center post-market study demonstrate that retrograde viewing of the colon with the Third Eye improves the detection of polyps and adenomas compared to traditional colonoscopy alone. Results were statistically significant.

## Conclusions j)

Avantis Medical Systems, Inc. has determined, based on clinical data, that the Third Eye improves the detection of polyps and adenomas in patients for whom colonoscopies are indicated. Risks to patients in terms of adverse events are comparable to those reported in the literature for traditional screening colonoscopies. Use of the Third Eye did not increase the risks to the patients but offered a statistically significant benefit of improved detection. Results of the clinical study are included in the Instructions for Use.
