| 摘要 |
An endograft introducer assembly having a transfer sheath is disclosed. The assembly includes a pusher assembly comprising a guide wire catheter (12), a tip (14) mounted to a proximal end of the guide wire catheter, a stent graft receiving portion (24) distal of the tip (14) and a pusher (21) distal of the receiving portion (24). The assembly further includes a transfer sheath (30) extending distally over the stent graft receiving portion from a proximal position adjacent to the tip, the transfer sheath having a first length over the stent graft receiving portion; and a stopper (40) disposed co-axially around the transfer sheath (30). The stopper has a proximal end (42) terminating in a stopper surface (44) and a distal portion (46), the distal portion removably engaged with the transfer sheath (30) so as to prevent relative axial movement between the stopper and the transfer sheath in at least one direction. |
