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.
