Abstract: Systems, devices, and methods for planning an endoscopic tissue acquisition procedure for acquiring tissue from an anatomical target are disclosed. An endoscopic system comprises a steerable elongate instrument and a processor. The steerable elongate instrument can be positioned and navigated in a patient anatomy and acquire tissue from an anatomical target via a biopsy tool associated with the steerable elongate instrument. The processor can receive an image of the anatomical target, apply the received image to a trained machine-learning (ML) model to determine a tissue acquisition plan that includes a recommended biopsy tool and operational parameters for navigating the steerable elongate instrument or maneuvering the recommended biopsy tool. The tissue acquisition plan can be presented to a user, or used to facilitate a robot-assisted tissue acquisition procedure.

Abstract: A stent includes a first tubular unit that has a cylindrical tubular shape and a mesh circumferential surface; and a second tubular unit that has a cylindrical tubular shape and a mesh circumferential surface, and is connected to the first tubular unit in a longitudinal axis direction of the stent. The first tubular unit has a first-first direction bent portion which is bent to be convex toward the first direction side that is one side of the longitudinal axis direction, the second tubular unit has a second-second direction bent portion which is bent to be convex toward the second direction side that is the other side of the longitudinal axis direction, and the first-first direction bent portion and the second-second direction bent portion form a first connecting portion that is connected so as to be relatively movable.

Abstract: Systems, devices, and methods for endoscopic access to a target region in a patient pancreaticobiliary system from an entry site of a stricture is disclosed. The stricture can be opened up using an radio-frequency (RF)-based approach by delivering RF energy to a working head of a steerable elongate instrument positioned at the entry site, or a mechanical puncture-based approach by applying force to a working head made of material with substantial stiffness. A machine learning (ML) model can be trained to determine a proper pancreaticobiliary access method for the patient, such as between the RF-based approach and the mechanical puncture-based approach. At least a distal portion of the steerable elongate instrument can be advanced into the pancreaticobiliary region to perform a diagnostic or therapeutic operation therein.
