1. A blood vessel access and closure assist system, comprising:
a procedural introducer sheath sized to be inserted into an artery, the procedural introducer sheath having an internal lumen for delivery of an interventional device into a blood vessel when the introducer sheath is inserted into an artery;
a vessel closure device delivery sheath, the vessel closure device delivery sheath having an internal lumen for use with a vessel closure device applier, the internal lumen adapted to deliver a vessel closure device onto a blood vessel;
the vessel closure device; and
the vessel closure device applier, wherein the vessel closure device applier has an elongated delivery shaft and a sharpened housing that contains the vessel closure device and wherein the sharpened housing is configured to tear the vessel closure device delivery sheath and advance the vessel closure device toward a distal tip of the elongated delivery shaft of the vessel closure device applier;
wherein the vessel closure device delivery sheath and the procedural sheath fixedly couple to one another to form a single assembly that can be inserted into an artery and wherein a distal end of the procedural sheath extends beyond a distal tip of the closure device delivery sheath when the two sheaths are coupled to one another.
