Intended Use

The EG-3830UT, Ultrasound Video Gastroscope, is intended to provide optical visualization of , ultrasonic visualization of, and therapeutic access to, the Upper Gastrointestinal Tract. The Upper Gastrointestinal Tract includes but is not restricted to, the organs; tissues; and subsystems: Esophagus, Stomach, Duodenum, Small Bowel, and underlying areas. The instrument is introduced per orally when indications consistent with the requirement for the procedure are observed in Adult and Pediatric patient populations.

Device Story

The EG-3830UT is a video ultrasound gastroscope used for upper GI tract visualization and therapy. It features a flexible insertion tube, control body, and umbilical connectors for video processors and ultrasound scanners. The device uses light-carrying bundles for illumination and a CCD to capture optical image data; a radial array ultrasound transducer captures ultrasonic data. The video processor compiles CCD data into full-color frames. The control body manages angulation, air/water delivery, suction, and balloon insufflation. A working channel allows for the introduction of biopsy forceps or other therapeutic instruments. Operated by physicians in clinical settings, the device provides real-time optical and ultrasonic images to assist in diagnosis and therapeutic procedures. The output allows clinicians to visualize internal structures and guide interventions, potentially improving diagnostic accuracy and therapeutic outcomes.

Clinical Evidence

No clinical data provided; substantial equivalence is based on bench testing and descriptive comparisons.

Technological Characteristics

Flexible endoscope with radial array ultrasound transducer and CCD imaging sensor. Features include air/water delivery, suction, and balloon insufflation controls. Connects to external video processor and ultrasound scanner. Immersible design (excluding scanner connector).

Indications for Use

Indicated for adult and pediatric patients requiring optical and ultrasonic visualization of, or therapeutic access to, the upper gastrointestinal tract (esophagus, stomach, duodenum, small bowel).

The EG-3830UT, Ultrasound Video Gastroscope, must be used with a Pentax Video Device Description: Processor (software controlled device) and must be used with Ultrasound Scanner (software controlled device). The endoscope has a Flexible Insertion Tube, a Control Body, PVE Umbilical Connector, and Scanner Umbilical Corvector. The PVE Connector connects to the Video Processor and has connections for illumination, video signals, air/water and suction. The Scanner Connected at the Ultrasound Scanner. The Control Body includes controls for up/ down/ left/ right angulation, air/water delivery, suction selection/ control, balloon insufflation, and an accessory inlet port. The device contains light carrying bundles to illuminate the body cavity, a charge couple device (CCD) to collect image data, and a radial array ultrasound transducer to collect ultrasonic image data. The instrument contains a working channel through which biopsy devices, or other devices, may be introduced (the instrument is supplied with two biopsy forceps). The Video Processor contains a lamp that provides white light that is filtered, via a Red, Green, and Blue color filter wheel, and is focused at the PVE Connector I.ightguide Prong. The endoscope light carrying bundles present the color strobes to the body cavity and the CCD collects image data for each strobe of color. The Video Processor stores the CCD information until all three color strobes are completed and a full color image frame is compiled. Image data and other screen display information are formatted and presented to the video outputs of the Video Processor for display. The ultrasound transducer delivers ultrasonic pulses, reflections of the pulses are received and signals are passed to the Ultrasound Scanner for display. The instrument is immersable (with the use of supplied cleaning accessories) except for the Ultrasound Scanner Connector (as described in the Endoscope operator Manual cleaning instructions).

Intended Use: The EG-3830UT, Ultrasound Video Gastroscope, is intended to provide optical visualization of, ultrasonic visualization of, and therapeutic access to, the Upper Gastrointestinal Tract. The Upper Gastrointestinal Tract includes but is not restricted to, the organs; tissues; and subsystems: Esophagus, Stomach, Small Bowel, and underlying areas. The instrument is introduced per orally when indications consistent with the requirement for the procedure are observed in adult and pediatric patient populations.

## Comparison To Predicated Device(s):

The submission for substantial equivalence included EG-3830UT literature including specifications, the identification of standard set components, and identification of optional accessories, comparison tables were provided to illustrate the comparisons to the predicated devices in summary. The submission for substantial equivalence was not based on an assessment of clinical performance data.
