Endoscopic ultrasound-guided biliary access system

ENDOSCOPIC ULTRASOUND-GUIDED BILIARY ACCESS SYSTEM Abstract The present disclosure provides an access system having a maneuverable catheter assembly configured for providing access to and navigating a desired vessel for subsequent treatment thereof. The access system includes an adjustable delivery handle assembly (10) and an access catheter subassembly (15) having a maneuverable access catheter (200) configured to be delivered to desired site (e.g., within duodenum) to assist in treatment of a condition (e.g., drainage of a bile ducts via Endoscopic Ultrasound Guided Biliary Drainage (EUS-BD) techniques). The access catheter (200) includes at least a distal section (204) having an adjustable portion (206) along a length thereof configured to transition to a pre-defined arcuate shape to provide directional control over the distal end (204) of the catheter (200) as it is navigated through a vessel (e.g., bile duct). The handle assembly (10) includes additional elements configured to allow a clinician to maneuver and manipulate the distal end (204) of the access catheter (200). C)%
