ENDOSCOPIC ULTRASOUND-GUIDED BILIARY ACCESS SYSTEM

摘要

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 and an access catheter subassembly having a maneuverable access catheter 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 includes at least a distal section having an adjustable portion along a length thereof configured to transition to a pre-defined arcuate shape to provide directional control over the distal end of the catheter as it is navigated through a vessel (e.g., bile duct). The handle assembly includes additional elements configured to allow a clinician to maneuver and manipulate the distal end of the access catheter.

主权项

1. A system for providing access to a vessel, the device comprising:
an adjustable delivery handle system comprising:
a delivery handle assembly, at least a portion of which comprises an inner lumen configured to receive one of a plurality of exchangeable subassemblies; anda sheath coupled to a distal end of the handle assembly and having a lumen in fluid communication with the inner lumen of the delivery handle assembly; and an access catheter subassembly removably disposed within the inner lumen of the delivery handle assembly and lumen of the sheath, the access catheter subassembly comprising:
an access catheter having an elongate tubular body having a proximal section having a proximal end, a distal section having a distal end, an outer surface, and an inner surface defining a lumen extending from the proximal end to the distal end,wherein the distal section includes an adjustable portion along a length thereof configured to transition to at least a pre-defined arcuate shape.
