Abstract:
A controlled stent-graft deployment delivery system ( or ) includes a stent-graft ( or ), a retractable primary sheath () containing the stent-graft in a first constrained diameter configuration, an outer tube () within the retractable primary sheath and within the stent-graft, and an inner tube () within the outer tube, where the inner tube and the outer tube both axially move relative to the retractable primary sheath and to each other. The system further includes a cap () coupled to a distal end of the inner tube and configured to retain at least a portion of a proximal area of the stent-graft in a radially compressed configuration. A distal assembly () provides controlled relative axial movement between the outer tube and the inner tube enabling the release of the proximal end (, and ) of the stent-graft from the cap and from the radially compressed configuration.
