Abstract: An information processing system, including a processor comprising hardware. The processor being configured to: acquire an endoscope image from an endoscope, the endoscope image showing a papillary portion, determine route information of a lumen based on the endoscope image, the lumen being at least one of a biliary duct or a pancreatic duct, generate a display image based on a result of the determination of the route information of the lumen, the display image having a route guide image to provide guidance of a route of the lumen leading to the papillary portion superimposed on the endoscope image, and display the display image on a display.

Abstract: Systems, devices, and methods for integrating images from various sources and using the same to guide endoscopic procedures are disclosed. An endoscopic system comprises an endoscope to be positioned and navigated in a patient anatomy, and a processor configured to reconstruct a three-dimensional (3D) image of an anatomical target based on at least two images of the anatomical target. The at least two images can be calibrated and registered using respective landmarks. One or more secondary images can be integrated with the reconstructed 3D image. The reconstructed image or the integrated image, along with the endoscope navigation plan, can be displayed to a user. Based on the reconstructed or the integrated image, the processor can generate an endoscope navigation plan for use in an image-guided endoscopic procedure.

Abstract: A deflection mechanism for an elongate medical device may comprise an actuator. The actuator may comprise a rotatable body comprising a channel, the channel comprising a plurality of recesses. The deflection mechanism may further comprises an activation wire having a proximal end and a distal end, and a wire lock attached to the proximal end of the activation wire. The wire lock may be disposed within the channel and configured to ride therein when the actuator body is rotated. An adjustable stop may be placed in one or more of the recesses of the channel so as to apply a force to the wire lock as the actuator is rotated so as to increase tension on the activation wire.
