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: 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.

Abstract: Systems, devices, and methods for providing an endoluminal transhepatic access to a patient pancreaticobiliary system in an endoscopic procedure are disclosed. An example of a transhepatic access procedure comprises navigating a steerable elongate instrument through a body cavity or channel and exiting to a access site of liver, puncturing the liver from the access site, extending the steerable elongate instrument through the liver and into the pancreaticobiliary system and performing an operation therein. Following the operation, the steerable elongate instrument can be retreated, and the access site of liver can be closed with a closure means. Apparatus and methods of training a machine-learning model and using said model to identify patient candidacy for retrograde access based on images of patient anatomy are also disclosed.
