摘要：Y-stents and delivery apparatus for delivering the Y-stents include a delivery catheter with an open distal end having two, circumferentially opposed extensions separated by two receiving portions which receive an anatomical junction.
主权项：1. A delivery catheter for a bronchial Y-stent configured to maintain patency between a trunk airway and two bronchial branches separated by a bronchial junction, said delivery catheter comprising: a tubular portion comprising, a proximal portion and a distal portion; said distal portion comprising two, spaced and circumferentially opposing extensions defining an unobstructed distal opening; said extensions comprising distal ends; said extensions are separated by two, proximally extending receiving sections configured to receive a bronchial junction when said extensions extend into adjacent bronchial branches, said receiving sections comprising proximal portions which do not extend distally as far as the distal ends of said extensions, and wherein said extensions are configured to extend into adjoining bronchial branches when said proximal portions of said relieved portions are abutting a bronchial junction.
