    摘要： A stent-graft deployment system (10) can include a stent-graft (15), a catheter (21) having a flexible catheter tip (12) attached to a catheter shaft of the catheter, a retractable primary sheath (20) containing the stent-graft in a first constrained small diameter configuration around the catheter shaft near the flexible tip, and a pushrod (18) having a cup (16) containing part of or substantially all of a distal spring at the end thereof for retaining a distal end of the stent graft in a constrained position. The cup plunger moves coaxially in relation to the catheter and the retractable primary sheath. The stent-graft deployment system can further include a release plate (17) coupled to the catheter and with the release plate held stationary the cup moves coaxially relative to the release plate acting as a barrier so as the cup retracts the proximal end of the stent graft beyond an outer edge of the cup is exposed to release the stent-graft from the constrained position to enable stent-graft deployment.

    摘要： A controlled stent-graft deployment delivery system (10 50 or 900) includes a stent-graft (30 or 63), a retractable primary sheath (40) containing the stent-graft in a first constrained diameter configuration, an outer tube (18) within the retractable primary sheath and within the stent-graft, and an inner tube (20) 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 (15) 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 (100) provides controlled relative axial movement between the outer tube and the inner tube enabling the release of the proximal end (65, 67, 68, and 69) of the stent-graft from the cap and from the radially compressed configuration.
