A vessel access and closure assist system is used for accessing a vessel to perform a vascular intervention. The system facilitates the delivery of a vessel closure device onto a blood vessel for closing an opening in the wall of the blood vessel. The vessel access and closure assist system includes a procedural introducer sheath that directly couples to a vessel closure device delivery sheath such that the procedural introducer sheath does not have to be exchanged with the vessel closure device delivery sheath.
