PENTAX Medical Video Duodenoscope ED34-i10T2s

The PENTAX Medical Video Duodenoscope ED34-i10T2s is intended to be used with endoscopic devices and other ancillary equipment to provide optical visualization of (via a video monitor), and therapeutic access to the biliary tract via the upper gastrointestinal tract. This anatomy includes the organs; tissues; and subsystems of the: esophagus, stomach, duodenum, common bile duct, hepatic ducts, cystic duct, and pancreatic duct.

This endoscope is introduced via the mouth when indications consistent with the need for the procedure are observed in adult and pediatric patient populations.

PENTAX Gas/Water Feeding Valve OF-B194

Gas/water feeding valve is attached in place of air/water feeding valve to the gastrointestinal endoscope, in order to prevent the leaking of the nonflammable gas into the room, and feed the gas or water into the gastrointestinal tract or abdominal cavity. It also prevents back flow/splashing of body fluids.

PENTAX Medical Video Processor EPK-i8020c

The PENTAX Medical Video Processor EPK-i8020c is intended to be used with the PENTAX Medical camera heads, endoscopes, light sources, monitors and other ancillary equipment for gastrointestinal and pulmonary endoscopic diagnosis, treatment and video observation.

The PENTAX Medical EPK-i802Oc includes a digital post-processing imaging enhancement technology (PENTAX i-ScanTM), and optical imaging enhancement technology (OE). These imaging enhancement technologies are intended to be used as an optional adjunct following traditional white light endoscopy and is not intended to replace histopathological sampling. i-Scan and OE are compatible with PENTAX Medical video gastrointestinal endoscopes and bronchoscopes.

PENTAX Medical Single Use, Sterile Distal End Cap with Elevator OE-A63

The PENTAX Medical Single Use, Sterile Distal End Cap with Elevator OE-A63 fully integrates a movable elevator, whose function it is to guide endoscopic devices. The OE-A63 is controlled by the PENTAX Medical Video Duodenoscopes and is necessary to meet the intended use of the duodenoscope.

Indications for use as stated in the FDA summary.
