METHOD AND APPARATUS FOR INTRODUCING EXPANDABLE INTRALUMINAL PROSTHESIS

摘要

A stent introducer (100) has a delivery sheath (60) positioned to restrain a self expandable stent (30). A pull wire (50a; 50b) is connected with the delivery sheath and extends through a pull wire lumen (41a, 41b) to enable remote retraction of the delivery sheath. The distal end of the pull wire lumen is associated with a region of weakness in the structure such that the region of weakness is torn on retraction of the delivery sheath.
