A method and apparatus for closing a vascular wound includes a guidewire and/or
other surgical implement extending from the wound. A hemostatic material is advanced
over the surgical implement and into contact with an area of the blood vessel surrounding
the wound. The surgical implement is removed. Blood soaks the hemostatic material,
and blood clotting is facilitated by the hemostatic agent within the material.
A sealing layer of adhesive can be applied to the hemostatic material, confining
the blood flow to the material. Thus, the vascular puncture wound is sealed by
natural blood clot formation.
