Publication number: 20230128263Abstract: A catheter system may comprise an articulation joint including a first pair of links and a second pair of links. Each link may include a central channel enclosed at least in part by radially extending arcuate segments. The first pair of links may include a first link and a second link, and the second pair of links may include the second link and a third link. The system may also comprise a first pair of springs coupled between the first and second links. The system may also comprise a second pair of springs coupled between the second and third links. The system may also include control wires extending through the first pair of springs and a control wires extending through the second pair of springs. The spring walls may share a radial dimension with the link walls.Type: ApplicationFiled: October 24, 2022Publication date: April 27, 2023Inventors: CHRISTOPHER M. MAJOR, Joseph D. Bogusky, Lucas S.

Publication number: 20130289352Abstract: A video endoscope system includes a reusable control cabinet and an endoscope that is connectable thereto. The endoscope may be used with a single patient and then disposed. The endoscope includes an illumination mechanism, an image sensor, and an elongate shaft having one or more lumens located therein. An articulation joint at the distal end of the endoscope allows the distal end to be oriented by the actuators in the control cabinet or actuators in a control handle of the endoscope. Fluidics, electrical, navigation, image, display and data entry controls are integrated into the system along with other accessories.Type: ApplicationFiled: March 20, 2013Publication date: October 31, 2013Applicant: Boston Scientific Scimed, Inc.Inventors: Dennis R. BOULAIS, Francis T. MACNAMARA, Andrew P. KIROUACA

Patent number: 8567033Abstract: A method of constructing an articulation joint includes forming a metallic tube with a number of rings formed therein. Springs may be secured to the inside surface or outside surface of the rings to allow the joint to bend in directions transverse to the axis of the springs. A fixture may be used to hold the springs at the correct position within the tube and the springs may be urged toward the rings or vice versa to obtain a good bond between the springs and the rings.Type: GrantFiled: September 8, 2011Date of Patent: October 29, 2013Assignee: Boston Scientific Scimed, Inc.Inventor: Francis T.
