1. An apparatus for using a volume of a patient's whole blood to close a subcutaneous arterial wound in the patient, comprising:
a syringe;
a valve coupled to the syringe;
a pulsatile indicator;
a tube having a proximal end and a distal end;
a porous matrix; and
a cylindrical enclosure coupled to the tube and at least partially surrounding the porous matrix and configured to, in cooperation with the tube, effect homogenous exposure of the patient's whole blood to the porous matrix to initiate a clotting cascade in the patient's whole blood;
wherein the tube and porous matrix are further configured to situate the patient's whole blood at a position proximate the arterial wound as the patient's whole blood is clotting in order to form a hemostatic closure comprising the patient's whole blood.
