An apparatus (430) for closing a vascular wound includes an apparatus that can be threaded over a guidewire(458) into place at or adjacent the wound. The apparatus includes a chamber(520) that encloses a hemostatic material (270) therein. When the apparatus is positioned adjacent the wound as desired, the hemostatic material is deployed from the chamber. 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.

La présente invention concerne un appareil qui permet de fermer une lésion vasculaire, lequel appareil comprend un appareil qui peut être enfilé sur un fil-guide jusque sur la lésion ou adjacent à celle-ci. L'appareil comprend une chambre dans laquelle est enfermé un matériau hémostatique. Lorsque l'appareil est placé adjacent à la lésion dans la position souhaitée, le matériau hémostatique est déployé de la chambre. Le sang entre en contact avec le matériau hémostatique, et la coagulation est de préférence facilitée par un agent hémostatique à l'intérieur du matériau. L'invention permet de cette manière la formation d'un caillot sanguin qui vient fermer hermétiquement la perforation vasculaire.
