Publication number: 20020156454Abstract: This invention provides novel instrumentation surface structure for catheters, guide wires and other instrumentation for entering body canals to an internal body work site. This instrumentation is structured with a bi-directional surface friction for engaging tissue within the cavities and canals that they navigate. In this manner the naturally occurring peristalatic contractions are employed to advantageously grasp and carry the instrumentation toward its desired work site, significantly decreasing the risks of puncture and significantly decreasing the surgeon's time for entry of instruments to desired work sites in such procedures as small bowel enteroscopy where an endoscope enters the esophagus to be dynamically moved to work sites in the small intestine or colonoscopy where an endoscope enters the anal canal to be moved through the entire colon and gradually into the terminal ileum.Type: ApplicationFiled: November 2, 1998Publication date: October 24, 2002Inventor: BORIS REYDEL

Patent number: 6464685Abstract: An endoscopic ligation kit including an inner cylinder, an outer cylinder having at least two step portions of diminishing outer radii formed on the outer periphery of its distal end portion, and a slide cylinder provided between the inner cylinder and the outer cylinder. The outer cylinder has a notch extending from its distal end portion to its maximum outer diameter portion. The slide cylinder has at its distal end portion a projection which conforms in size to the notch, and has steps and the projection is fitted in the notch. O-rings are mounted respectively on the outer periphery of the distal end portion of the inner cylinder and the step portions of the outer cylinder.Type: GrantFiled: September 7, 2000Date of Patent: October 15, 2002Assignee: Sumitomo Bakelite Company LTDInventors: Zenetsu Suzuki, Haruhiko Masuda

Patent number: 6428566Abstract: A delivery sheath including a series of longitudinally spaced apart retainer rings interconnected by flexible links. This configuration provides for sections of reduced cross-sectional area along the length of the sheath, thus increasing flexibility in those sections and in the overall sheath. The reduction of the cross-sectional area of the sheath also effectively reduces the area of contact between the inside surface of the sheath and the outside surface of the compressed stent. This reduction in contact area serves to reduce the frictional force generated as the sheath is retracted relative to the stent during deployment.Type: GrantFiled: October 31, 2000Date of Patent: August 6, 2002Assignee: Advanced Cardiovascular Systems, Inc.Inventor: Vivianne M. Holt

Patent number: 6406453Abstract: A medical ventilation tube for placement in an opening formed in an anatomical structure, such as the tympanic membrane of the ear, includes a hollow tubular shaft made of a first material having a hardness or durometer to maintain a passage through the shaft when the medical ventilation tube is placed in the opening, and a flange made of a second material having a hardness or durometer less than that of the first material to permit the flange to deform in response to contact with the anatomical structure during removal of the medical ventilation tube from the opening.Type: GrantFiled: April 26, 1995Date of Patent: June 18, 2002Assignee: Medtronic Xomed, Inc.Inventors: Richard L. Goode, F. Barry Bays

Publication number: 20020013715Abstract: In a method of configuring a blood circuit for medical application, one unit component is selected for each of the divided unit sections and the selected unit components are combined to configure a blood circuit component. A blood circuit system database in which data with respect to the unit sections and unit components are stored is used. On the basis of the database, the selected unit component input to the computer. An assembly drawing of the blood circuit obtained by combining the selected unit components, a full length and an amount of filled blood are displayed on a display by using the database. When the displayed assembly drawing etc. is not fit for the desired specification, the selection of the unit component is changed, so as to display again the assembly drawing etc. of the blood circuit.Type: ApplicationFiled: May 30, 2001Publication date: January 31, 2002Applicant: JMS CO., LTD.Inventors: Kunio Yoshinaga, Hirosato Maehama, Noriaki Nakagawa

Publication number: 20010049519Abstract: A hub assembly for a catheter tube having a lumen therethrough. The hub assembly includes a hub portion having a proximal end and a distal end, and an integral connector disposed at the proximal end. A lumen is defined through the hub portion extending from the proximal end to the distal end. The strain relief includes a proximal end and a distal end is disposed at the distal end of the hub portion. The proximal end of the strain relief can be integrally connected to the distal end of the hub portion. The strain relief is preferably more flexible than the hub portion. The strain relief defines a passage configured to receive the catheter such that a lumen through the hub portion is in fluid communication with the catheter tube lumen.Type: ApplicationFiled: June 25, 2001Publication date: December 6, 2001Inventors: Thomas J. Holman, John E. Arnold, Gregory K. Olson, Todd A. Berg

Patent number: 6190372Abstract: Compressible lock washers for use in catheter connectors. One such lock washer (60) includes a support ring (62) and tube engagement flanges (64) extending centrally therefrom, oblique to the ring and each extending from the same side thereof. The tube engagement flanges (64) define a tube receptacle (72) through which a catheter tube (58) may be inserted. Upon compression of the lock washer (60), the tube engagement flanges (64) are forced toward the ring (62), decreasing the diameter of the tube receptacle (72). Thus, during compression of the lock washer (60), the tube engagement flanges (64) engage the catheter tube (58) which runs through the tube receptacle (72), securing the catheter tube within the catheter connector (20) with which the lock washer is associated.Type: GrantFiled: August 14, 1998Date of Patent: February 20, 2001Assignee: Epimed International, Inc.Inventor: N. Sandor Racz
