ABSTRACT:
A pass-through duodenal enteroscopic device utilizes the natural contraction wave of the small intestine to propel the device through the small intestine at about the same speed as any other object therein. The exterior of the device is streamlined over the greater portion thereof with a video camera and illumination source at the forward end of the device. Covering the camera lens and illumination source is a transparent inflatable balloon adapted to gently expand the small intestine immediately forward the camera for better viewing. A small diameter communication and power cable is wound within the device and unwinds through an aperture in the rear of the device as the device moves through the small intestine. Upon completion of movement through the small intestine the cable is automatically separated from the device permitting the cable to be withdrawn through the stomach and intestine. The device continues through the large intestine and passes from the patient through the rectum.
