Abstract: A capsule assembly for an endograft introducer is disclosed. The assembly comprises: a capsule and a capsule plug. The capsule has a cavity for receiving an end of a stent graft and a capsule wall terminating in a distal end. The capsule plug comprises: a tip portion having a lead-in surface and an abutment surface; and a tail portion having an external surface engageable with an inside surface of the capsule wall. The capsule is slideably movable with respect to the capsule plug from a first position in which the distal end of the capsule wall surrounds an opening into the cavity to a second position in which the distal end of the capsule wall is positioned proximally with respect to the abutment surface, whereby movement of the tip portion into the capsule is resisted by abutment between the distal end of the capsule wall and the abutment surface.

Abstract: A stent graft and delivery device assembly comprises a dilator 3, a stent graft receiving portion distal of the dilator, an elongate seal-engaging sleeve portion 185 distal of the stent graft receiving portion, a stent graft 35 mounted on the stent graft receiving portion, a stent graft cover 100 mounted around the stent graft, the cover having a maximum outer diameter, and an introducer 40 disposed around the elongate seal-engaging sleeve portion. The introducer has a hollow body, a haemostatic device 33 and an introducer catheter 45 extending from the hollow body. The inner diameter D of the catheter is greater than the outer diameter Y of the seal-engaging sleeve portion 185. The seal-engaging sleeve portion has a maximum outer diameter Y less than the maximum outer diameter C of the cover 100.
