An apparatus for sealing a puncture extending through tissue to a blood vessel includes a guidewire including an expandable tamp, a retaining sheath for covering the tamp, and a delivery sheath including a primary lumen for receiving the guidewire therethrough and a secondary lumen for delivering sealing compound into the puncture. After introducing the sealing compound, the delivery sheath is removed, and an introducer sheath is advanced over the guidewire to provide access to perform a medical procedure via the vessel after removing the guidewire.
L'invention concerne un appareil destiné à étanchéifier une perforation traversant un tissu jusqu'à un vaisseau sanguin, et comprenant un fil guide pourvu d'un élément extensible, une gaine de retenue recouvrant le piston, ainsi qu'une gaine de distribution comportant une lumière principale à travers laquelle le fil guide peut être reçu et une lumière secondaire permettant de distribuer le composé d'étanchéité dans la perforation. Après l'introduction du composé d'étanchéité, on enlève la gaine de distribution et l'on fait avancer une gaine d'introduction sur le fil guide, d'où l'obtention d'une voie d'accès permettant la réalisation d'une opération médicale par l'intermédiaire du vaisseau après le retrait du fil guide.
