CA 2119027

A puncture seal device (32) for stemming the flow of blood from a punctured blood vessel (150) comprises an elongated outer sheath (40) affixed to a generally tubular housing (30) where the housing contains a manually actuable slide (48) which is affixed to a rigid tubular pusher member (48) coaxially disposed within the outer sheath. Also contained within the outer sheath in longitudinal alignment with the pusher and distally thereof is a ring-shaped plug of a hemostatic material (44). The assembly thus far described may be fitted over a tubular introducer or the body of a catheter (18) and then advanced therealong until the distal end of the outer sheath is proximate a bleeding blood vessel. By actuating the pusher member, the hemostatic plug surrounding the introducer or catheter is ejected from the distal end of the outer sheath (42) and held in abutting relationship to the bleeding blood vessel.

Dispositif de scellement de perforation (32) pour contenir l'écoulement du sang d'un vaisseau sanguin perforé (150). Le dispositif comprend une gaine extérieure allongée (40) fixée à un boîtier de forme généralement tubulaire (30) contenant une glissière à action manuelle (48) fixée à un piston tubulaire rigide (48) disposé dans le même axe dans la gaine extérieure. Cette dernière contient également un bouchon annulaire fait d'un matériau hémostatique (44) en alignement longitudinal avec le piston et à son extrémité distale. L'assemblage décrit peut être placé sur un introducteur tubulaire ou sur le corps d'un cathéter (18), puis engagé le long de celui-ci jusqu'à ce que l'extrémité distale de la gaine extérieure se trouve à proximité d'un vaisseau perforé. En actionnant le piston, le bouchon hémostatique entourant l'introducteur ou le cathéter est éjecté de l'extrémité distale de la gaine extérieure (42) et maintenu en place sur le vaisseau sanguin perforé.
