Abstract

In one aspect, the present invention is a system for preparing a patient for an endoscopy procedure, such as a colonoscopy. The endoscopic preparation and examination system includes an endoscope, a source of irrigation and aspiration, and a control unit. The endoscope includes an elongated flexible shaft with a distal tip and a proximal end, at least one aspiration lumen and at least one irrigation lumen. A plurality of irrigation ports are functionally connected to the at least one irrigation lumen and a plurality of aspiration ports are functionally connected to the at least one aspiration lumen. In another aspect, the invention provides a method of clearing an obstructed view in a patient prior to, or during an endoscopic examination.
