Patent

CA 2700849

The invention provides an applicator for forming a hole in a wall of a hollow organ and for connecting a hemostatic connection assembly to the hollow organ, wherein, when the hole is formed in the wall of the hollow organ, a first fluid seal exists between the hemostatic connection assembly and the wall of the hollow organ and a second fluid seal exists between the hemostatic connection assembly and the applicator, thereby minimizing fluid loss from the hollow organ. The invention further provides a hemostatic connection assembly for connecting an inlet conduit to a hollow organ, the hemostatic connection assembly comprising a organ wall connection portion, a cuff portion, an extension portion, and a seal ring portion, wherein, during the process of connecting the inlet conduit to the hollow organ, a first fluid seal exists between the organ wall connection portion and the wall of the hollow organ, and a second fluid seal exists between the hemostatic connection assembly and the inlet conduit, thereby minimizing fluid loss from the hollow organ. A method is also disclosed in which the applicator and hemostatic connection assemblies of the invention are used to connect an inlet conduit to a hollow organ.

L'invention concerne un applicateur servant à former un trou dans la paroi d'un organe creux et à connecter un assemblage de connexion hémostatique à l'organe creux. Quand le trou est formé dans la paroi de l'organe creux, un premier colmatant fluide sort entre l'assemblage de connexion hémostatique et la paroi de l'organe creux et un second colmatant fluide sort entre l'assemblage de connexion hémostatique et l'applicateur, ce qui permet de minimiser la perte de fluide provenant de l'organe creux. L'invention concerne en outre un assemblage de connexion hémostatique servant à connecter un conduit d'admission à un organe creux, l'assemblage de connexion hémostatique comportant une partie de connexion à la paroi d'un organe, une partie de manchon, une partie d'extension et une partie de bague d'étanchéité. Lors du procédé de connexion du conduit d'admission à l'organe creux, un premier colmatant fluide sort entre la partie de connexion à la paroi d'un organe et la paroi de l'organe creux, et un second colmatant fluide sort entre l'assemblage de connexion hémostatique et le conduit d'admission, ce qui permet de minimiser la perte de fluide provenant de l'organe creux. L'invention décrit également un procédé dans lequel l'applicateur et les assemblages de connexion hémostatique sont utilisés pour connecter un conduit d'admission à un organe creux.
