Stent delivery system with pusher assembly

摘要

A pusher assembly for a stent delivery device includes a distal end of an elongate inner member and a stent-engaging member having a proximal end and a distal end. The proximal end of the stent-engaging member is at least partially inside the distal end of the elongate inner member. The stent-engaging member includes a portion that radially outwardly extends towards the distal end of the stent-engaging member. The stent-engaging member is configured to move a stent when distally advanced and is configured to not move a stent when proximally retracted.
