Abstract

A pusher assembly for a stent delivery device includes a distal end of an elongate member and a stent-engaging member having proximal and distal ends. The proximal end of the stent-engaging member is mechanically coupled to the distal end of the inner member by a connector, or 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, or 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 configured to not move a stent when proximally retracted. A stent delivery device includes an elongate outer member, an elongate inner member coaxially positioned within the outer member, and the pusher assembly.
