摘要： A proximal stent-graft retention system includes a stent-graft having a suture loop attached to a proximal end of the stent-graft and a delivery catheter having a distal tip that includes a retention feature. The retention feature can include a slot extending through a sidewall of the distal tip and a trigger wire. The slot of the distal tip exposes a portion of the trigger wire within the tip lumen such that the trigger wire may extend through the suture loop of the stent-graft at the slot of the distal tip of the delivery catheter and is configured to retain the proximal end of the stent-graft in the radially expanded configuration via the suture loop to prevent distal migration and compression of the stent-graft. Proximal retraction of the trigger wire releases the suture loop of the stent-graft such that the stent-graft is no longer coupled to the delivery catheter.
