ENDOSCOPIC ULTRASOUND-GUIDED BILIARY ACCESS SYSTEM

摘要

The present disclosure provides an access system having a maneuverablecatheter assemblyconfigured for providing access to and navigating a desired vessel forsubsequent treatmentthereof. The access system includes an adjustable delivery handle assembly andan accesscatheter subassembly having a maneuverable access catheter configured to bedelivered todesired site (e.g., within duodenum) to assist in treatment of a condition(e.g., drainage of abile ducts via Endoscopic Ultrasound Guided Biliary Drainage (EUS-BD)techniques). Theaccess catheter includes at least a distal section having an adjustableportion along a lengththereof configured to transition to a pre-defined arcuate shape to providedirectional controlover the distal end of the catheter as it is navigated through a vessel (e.g.,bile duct).
