Abstract:
1. A stent loading and deployment device comprising: an outer tube having a distal end, a longitudinal length, and defining a lumen; an intermediate tube positioned in the lumen of the outer tube, the intermediate tube having a distal end, a longitudinal length, and defining a lumen; an inner tube positioned in the lumen of the intermediate tube, the inner tube defining a lumen and having a distal end and a longitudinal length greater than the longitudinal length of the intermediate tube and the longitudinal length of the outer tube; the outer tube, the intermediate tube, and the inner tube being independently movable in a longitudinal direction; the stent loading and deployment device having a fully loaded configuration, a delivery configuration, and a stent deployment configuration, the stent loading and deployment device being in the stent deployment configuration after being in the fully loaded and delivery configurations; wherein: in both the fully loaded and the delivery configurations the distal ends of the outer and inner tubes are axially aligned to define a stent deployment region for a loaded stent, the stent deployment region entirely covered by the outer tube, and the distal end of the intermediate tube is proximal to the axially aligned distal ends of the outer and inner tubes and to a distal end of the stent deployment region; and in the stent deployment configuration, at least a portion of the stent deployment region is uncovered by the outer tube; the outer tube having an outer tube handle at a proximal end, the intermediate tube having an intermediate tube handle at a proximal end, and the inner tube having an inner tube handle at a proximal end, wherein: the intermediate tube handle has a distal opening larger than a proximal opening; and the inner tube has: a distal portion with a first diameter, the distal portion slidable through only a portion of the intermediate tube handle so that relative axial movement of the intermediate tube and the inner tube is limited; a proximal portion with a second diameter less than the first diameter, the proximal portion is slidably disposed within the intermediate tube handle.
