DELIVERY SYSTEM FOR DELIVERING A GRAFT FROM THE MIDDLE THEREOF

摘要

Delivery system (100), delivering a graft (124) through a surgically created opening, including a main tube (102,104), an inner tube (108), a distal stent (120), a distal cap (118), and an externally extending tube (116), the main tube includes a proximal portion (102), and is coupled with the inner tube and the externally extending tube, the externally extending tube pulls the proximal portion proximally, thereby positioning the middle of the graft adjacent to the opening, the cap covers the stent, the inner tube pushes the cap distally, thereby exposing the stent, the stent anchors the graft onto the blood vessel, the externally extending tube pushes the main tube distally, thereby positioning the main tube distally to the opening, the externally extending tube pulls the main tube out through the expanded stent and the opening, the proximal portion is located adjacent to the externally extending tube during delivery into the blood vessel, the proximal portion detaches from the externally extending tube after delivery into the blood vessel.
