Intended Use

The EG-3400, Video Gastroscope, is intended to provide optical visualization (via a video monitor) of, and therapeutic access to, the Upper Gastrointestinal Tract. The Upper Gastrointestinal Tract includes, but is not limited to, the organs; tissues; and subsystems: Esophagus, Stomach, Duodenum, and Small Bowel. The instrument is introduced per orally when indications consistent with the requirement for procedure(s) are observed in Adult and Pediatric patient populations.

Device Story

EG-3400 is a video gastroscope used for visualization and therapeutic access to the upper GI tract. Input: light reflected from body cavity via CCD sensor. Operation: device connects to a video processor containing a 300W xenon lamp; light is filtered through an RGB color wheel; CCD collects image data per color strobe; processor compiles full-color frames. Output: video feed displayed on a monitor for physician use. Used in clinical settings by physicians. Features flexible insertion tube, angulation controls, air/water delivery, suction, and working channel for biopsy forceps. Benefits: enables minimally invasive diagnostic and therapeutic procedures in the esophagus, stomach, duodenum, and small bowel.

Clinical Evidence

No clinical data; bench testing only.

Technological Characteristics

Flexible insertion tube, control body, umbilicus. Sensing: CCD. Illumination: 300W xenon lamp with RGB color wheel filtering. Connectivity: proprietary connection to video processor. Working channel for accessory introduction.

Indications for Use

Indicated for adult and pediatric patients requiring optical visualization and therapeutic access to the upper gastrointestinal tract, including the esophagus, stomach, duodenum, and small bowel.

Regulatory Classification

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.

Special Controls

*Classification* —(1)*Class II (special controls).* The device, when it is an endoscope disinfectant basin, which consists solely of a container that holds disinfectant and endoscopes and accessories; an endoscopic magnetic retriever intended for single use; sterile scissors for cystoscope intended for single use; a disposable, non-powered endoscopic grasping/cutting instrument intended for single use; a diagnostic incandescent light source; a fiberoptic photographic light source; a routine fiberoptic light source; an endoscopic sponge carrier; a xenon arc endoscope light source; an endoscope transformer; an LED light source; or a gastroenterology-urology endoscopic guidewire, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.(2) Class I for the photographic accessories for endoscope, miscellaneous bulb adapter for endoscope, binocular attachment for endoscope, eyepiece attachment for prescription lens, teaching attachment, inflation bulb, measuring device for panendoscope, photographic equipment for physiologic function monitor, special lens instrument for endoscope, smoke removal tube, rechargeable battery box, pocket battery box, bite block for endoscope, and cleaning brush for endoscope. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807of this chapter, subject to the limitations in § 876.9.

TEL: [phone]

2. NAME OF DEVICE:
Trade Name: EG-3400, Video Gastroscope
Classification Name: Gastroscope, Gastro- Urology (78FDS), 876.1500

3. PREDICATED DEVICE(S) INFORMATION:
1. FG-23H, Fiber Gastroscope Pentax K850020
2. EC-3800L, Video Colonoscope Pentax K951574
3. EPM-3300, Video Processor Pentax K934918

4. DEVICE DESCRIPTION:
The EG-3400, Video Gastroscope, must be used with a Video Processor (a software controlled device). The endoscope has a flexible insertion tube, a control body, and umbilicus. The umbilicus provides connection to the video processor. The control body includes controls for up/ down/ left/ right angulation, air/water delivery, suction, and an accessory inlet port. The device contains light carrying bundles, to illuminate the body cavity, and a charge couple device (CCD) to collect 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 300 watt xenon lamp which provides white light that is filtered, via a Red, Green, Blue color wheel, and is focused at the connected video endoscope lightguide 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 frame is compiled. Image data and other screen display information are formatted and presented to the video outputs of the video processor for display.

5. INTENDED USE:
The EG-3400, Video Gastroscope, is intended to provide optical visualization (via a video monitor) of, and therapeutic access to, the Upper Gastrointestinal Tract. The Upper Gastrointestinal Tract includes, but is not limited to, the organs; tissues; and subsystems: Esophagus, Stomach, Duodenum, and Small Bowel. The instrument is introduced per orally when indications consistent with the requirement for procedure(s) are observed in Adult and Pediatric patient populations.
