Abstract:
1. A device comprising: an outer sheath; a stent disposed within the outer sheath, the stent having a distal end and a proximal end; a stent-engaging element positioned at least partially within a lumen of the stent; and a stent-retention element configured to contact the proximal end of the stent; a handle coupled to the outer sheath such that the outer sheath cannot move relative to the handle; a user-actuatable element movable along the handle, the user-actuatable element being coupled to the stent-engaging element; a stopper biased to a first position that restricts distal advancement of the user-actuatable element, the stopper comprising a passageway, wherein the stopper has a second position that allows the user-actuatable element to pass through the passageway; wherein the device is configured such that: the stent-engaging element is configured to operate in a reciprocating manner to engage and advance the stent distally at least partially out of the outer sheath; and the stent-retention element will stay in contact with the stent during proximal movement of the stent-engaging element provided that the proximal end of the stent is disposed within the outer sheath and will cease contact when the proximal end of the stent is advanced outside of the outer sheath.
