Stent delivery systems and associated methods for delivering stents are disclosed herein. In several embodiments, a handle assembly for delivering a stent from a tubular enclosure can include a first lead screw having a first lead thread of a first pitch and first handedness, a second lead screw having a second lead thread of a second pitch and second handedness different from the first handedness, and a housing defining threads of the first and second pitches. The first lead screw can be in mechanical communication with the tubular enclosure, and the second lead screw can be in mechanical communication with the stent. Upon rotation of a portion of the housing, the housing threads can engage the lead screws so as to induce simultaneous translations of the lead screws in opposite directions. The simultaneous translations are configured to deploy the stent from the tubular enclosure.

Stent delivery systems and associated methods

Stent graft delivery systems are disclosed herein. In several embodiments, a stent graft delivery system can include a stent graft having a proximal portion and a distal portion, a proximal sheath and a distal sheath. The proximal sheath can be configured to cover the proximal portion of the stent graft, and the distal sheath can be configured to cover the distal portion of the stent graft. The proximal sheath and the distal sheath can be independently removable from respective ends of the stent graft such that the proximal and distal portions of the stent graft are independently deployable.
