Delivery system for delivering an endovascular graft within a blood vessel

A delivery system for delivering an endovascular graft within a blood vessel, the delivery system comprising:

• a tip assembly including a tip and a sleeve having an inner surface;
• and
• a tip capture mechanism, the tip assembly configured to move axially relative to the tip capture mechanism and between a delivery position and a release position, the tip capture mechanism includes a cylindrical outer surface including a proximal end and a distal end and knobs arranged around the cylindrical outer surface, each knob has a pyramidal structure with a rounded apex and a base having base edges, the base edges of the knobs and the proximal end and the distal end of the cylindrical outer surface bound smooth regions of the cylindrical outer surface, the smooth regions of the cylindrical outer surface are triangular shaped, and the knobs and inner surface of the sleeve configured to cooperate to hold a portion of the endovascular graft when the tip capture mechanism and the tip assembly are in the delivery position.
