  • Patent number: 7641638
    Abstract: Medical devices, kits, and methods for utilizing an elongate surgical needle that may be used through an endoscope working channel or through an external accessory channel device used with an endoscope are provided. The needle has a proximal end and a flexible distal end, an opening at or near the proximal end and an opening at or near the distal end, the openings defining a channel. The surgical needle distal end comprises a tissue engaging section and an intermediate section being operatively coupled in an axial direction. The tissue engaging section and intermediate section have different flexibility such that the tissue engaging section has greater flexibility than the intermediate section. Optionally, the needle distal end has a preformed bend at or near the tissue engaging section, the preformed bend capable of being constrained to a substantially linear configuration and capable of returning to the preformed configuration when unconstrained.

  • Publication number: 20060235269
    Abstract: A method, apparatus and kit for performing bile or pancreatic duct endoscopy. In some embodiments, the kit includes a wire adapted to be navigated perorally or pernasally to a position within the biliary tree or the pancreatic duct. The kit can further include an endoscope having a generally tubular body movable along the wire to and within the biliary tree or pancreatic duct. The kit can further include a tool dimensioned to be received within and movable along the tubular body of the endoscope. In some embodiments, the apparatus includes the wire, the endoscope and an overtube positioned over the endoscope and movable along the wire. Also, in some embodiments the method includes navigating the wire to within the biliary tree or pancreatic duct, and installing the endoscope over the wire to a position within the biliary tree or pancreatic duct.

  • Patent number: 5651769
    Abstract: A method for accurately and quickly positioning a double lumen gastroduodenal tube into predetermined locations utilizing an endoscopically placed guide wire to retrieve duodenal fluid uncontaminated by gastric fluid, with little or no discomfort to the patient, and minimal radiation exposure. Specifically, an endoscope is passed through a patent's esophagus and stomach into the duodenum such that its distal end is located at a predetermined location, such as the fourth portion of the duodenum. While the endoscope is held in place, a guide-wire is passed through its center instrument channel to position a distal end of the guide-wire adjacent to the distal end of the endoscope. The endoscope is then withdrawn from the patient, leaving the guide-wire.
