NaviCam Patency Capsule to Verify Gastrointestinal Patency

If the X-ray scan indicates that the capsule is not in the body or shows that the patency capsule is in the colonic area or if an intact patency capsule is found in the bowel movement, it proves that the intestine is patent, and the patient can undergo an examination using capsule endoscopy. If the X-ray scan shows that the capsule is still in the small bowel area, it indicates that there may be stricture(s) in the intestines, and then small bowel capsule endoscopy may not be performed.

The patency capsule is a disposable medical device composed of medicinal excipients in the shape of a dissolvable passive capsule and will dissolve over time if not excreted.
