  • Patent number: 8002698
    Abstract: With a first endoscope inserted through an overtube, the overtube is orally inserted into an object being examined, and a distal end portion of an insertion tube of the first endoscope is made to advance, within the object, from a jejunum via a jejunum-to-jejunum anastomosed portion and a jejunum-anastomosed bent portion so that the distal end portion is located adjacently to a Vater's papilla of a duodenum. The overtube is then sent to a position which is adjacent to the Vater's papilla along the insertion tube of the first endoscope. After this, the first endoscope is pulled from the overtube. A second endoscope is then inserted into the overtube to make a distal end portion of its insertion tube protrude from the distal end of the overtube and is located adjacently to the Vater's papilla. The second endoscope thus-approached is used to treat the Vater's papilla and the tissue therearound.

  • Patent number: 7976460
    Abstract: A catheter system is provided that permits easy cannulation and radiological examination of the biliary and pancreatic ducts during an Endoscopic Retrograde Cholangiopancreatograhy (ERCP) procedure. The system of biliary catheters provides for a method of gaining access to the biliary tree, particularly when the contralateral wall or septum of the biliary tree interferes with access to the biliary tree. This anatomical interference is remedied using a pulling biliary catheter that withdraws the papilla of Vater away from the contralateral wall or septum by pulling proximally upon a chute expanded within the papilla of Vater. The enlarged opening then permits additional medical devices to be advanced through the pulling biliary catheter into the desired duct requiring the ERCP procedure.

  • Patent number: 7591782
    Abstract: A balloon attaching jig is constituted by a ring member and a pair of nail members. After the insertion of the pair of nail members into an attaching hole of a balloon, the leading end of an insertion portion of an endoscope is pushed into an opening of the ring member. The diameter of the pair of nail members is expanded by a pushing-in force of the leading end of the insertion portion generated during this pushing in. As a result of this, the leading end of the insertion portion is inserted into the attaching hole of the balloon and hence the balloon can be easily attached to the leading end of the insertion portion of the endoscope.
