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.
L'invention concerne un procédé et un appareil pour occlure une blessure vasculaire comprenant un fil-guide et/ou tout autre outil chirurgical s'étendant dans la blessure. Une matière hémostatique est amenée sur un outil chirurgical et mis en contact avec une zone des vaisseaux sanguins entourant la blessure. Ledit outil chirurgical est enlevé. La matière hémostatique est imprégnée de sang, et la coagulation sanguine est facilitée par l'agent hémostatique à l'intérieur de la matière. Une couche d'occlusion adhésive peut être appliquée sur la matière hémostatique, pour confiner le flux sanguin vers la matière. Ainsi, la plaie de ponction vasculaire est occluse grâce à la formation naturelle d'un caillot.
