Abstract

Apparatus, systems, and methods are provided for deploying an implantable device, such as a stent, within a lumen of a body of a patient. The delivery device may include an inner member and an outer sheath surrounding a distal portion of the inner member and configured to retain the implantable device sheathed near the distal end of the outer sheath until deployment. The outer sheath is slidably moveable relative to the inner member such that proximal movement of the outer sheath relative to the inner member deploys the implantable device. A trigger assembly of the delivery device can include an internal connector coupled to the outer sheath, a plurality of triggers, and a floater coupling two of the triggers. The triggers are serially retracted to deploy the stent. A panchor secures the stent against proximal and distal movement relative to the inner member during deployment.
