Endograft delivery device assembly

An endovascular delivery device, for delivering an endograft, the device having a proximal end and a distal end, the delivery device comprising:

• an outer handle portion mounted to the distal end of the delivery device, the outer handle portion having a body portion and a track extending distally from the body portion;
• an inner handle portion, the inner handle portion slidably moveable within, and with respect to, the outer handle portion from a distal position to a proximal position;
• a tip assembly slider, mounted on the track for sliding movement with respect to the track;
• a tip assembly at the proximal end of the delivery device, the tip assembly comprising a top cap and a retriever, the tip assembly having an open configuration and a closed configuration, the top cap comprising a distally facing mouth, whereby in the open configuration, the mouth is open for receiving a proximal portion of the endograft, and in the closed configuration, the mouth is closed by the retriever;
• a connector extending from the tip assembly to the inner handle portion, the connector including a distal portion slidably engageable with the inner handle portion;
• a pusher catheter extending proximally from the outer handle assembly;
• a guide wire catheter extending through the inner handle portion and through the pusher catheter, the guide wire catheter being affixed at a distal end thereof to the inner handle portion and being affixed at a proximal end thereof to the tip assembly;
• an endograft receiving portion for receiving the endograft between the tip assembly and the pusher catheter;
• a distal trigger wire for releasably retaining a distal end of the endograft, whereby distal movement of the tip assembly slider pulls the distal trigger wire thereby releasing the distal end of the endograft;
• and
• a proximal trigger wire release slider mounted on the track distally of the tip assembly slider, for sliding movement with respect to the track from an initial position to a triggered position, wherein the tip assembly slider engages the proximal trigger wire release slider such that it cannot be moved distally until after the proximal trigger wire release slider has been moved distally;
• wherein the tip assembly slider is operably connected to the inner handle portion such that distal sliding movement of the tip assembly slider slides the tip assembly towards the pusher catheter.
