    摘要: A method and apparatus for closing a vascular wound includes an apparatus that can be threaded over a guidewire into place at or adjacent the wound. The apparatus includes a chamber that encloses a hemostatic material therein. When the apparatus is positioned adjacent the wound as desired, the hemostatic material is deployed from the chamber. A blocking member distal of the hemostatic material functions as a barrier to prevent the hemostatic material from entering the wound. Blood contacts the hemostatic material, and blood clotting preferably is facilitated by a hemostatic agent within the material. Thus, the vascular puncture wound is sealed by blood clot formation.

    摘要: An apparatus is provided for facilitating the locating and closing of an opening in a blood vessel. The apparatus includes a catheter and retractor that are advanced over a guidewire until they are positioned at or adjacent the vascular wound. The retractor comprises a plurality of members that close upon and engage the catheter. A coupling member selectively maintains the retractor members in the closed position.

    摘要: 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. The vascular puncture wound is sealed by natural blood clot formation.
