Abstract:
1. A delivery system for deploying an implantable device within a lumen internal to a body of a patient, the delivery system comprising: an inner member having a proximal end coupled to a handle of the delivery system and extending toward a distal end of the delivery system to couple to the implantable device; an outer sheath having a proximal end and a distal end, the 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, wherein 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 coupled to the outer sheath comprising: wherein the distal trigger and the proximal trigger are configured to be serially retracted to provide staged release of the implantable device such that retracting the proximal trigger moves the distal trigger and the outer sheath proximally and longitudinally relative to the inner member from a first position to a second position to partially deploy the implantable device, and wherein subsequent retraction of the distal trigger moves the outer sheath proximally and longitudinally relative to the inner member from the second position to a third position to fully deploy the implantable device.
