CA 2714889

Systems, devices, and methods permit insufflation of a body cavity prior to the insertion of a cannula into the body cavity. Some embodiments of an access system comprise an obturator, a trocar, and a fluid flow channel. The access system has a closed configuration, in which a distal end of the access system is fluidly isolated from the fluid flow channel, and an open configuration, in which the distal end of the access system is fluidly connected to the fluid flow channel, thereby permitting fluid flow, for example, an insufflation gas into a body cavity.

L'invention concerne des systèmes, des dispositifs et des procédés qui permettent le gonflement d'une cavité corporelle avant l'insertion d'une canule dans la cavité corporelle. Certains modes de réalisation du système d'accès comprennent un obturateur, un trocart, et un canal d'écoulement de fluide. Le système d'accès peut prendre une configuration fermée, dans laquelle une extrémité distale du système d'accès est isolée vis-à-vis des fluides du canal d'écoulement de fluide, et une configuration ouverte, dans laquelle l'extrémité distale du système d'accès est en connexion fluidique avec le canal d'écoulement de fluide, permettant ainsi l'écoulement du fluide, par exemple, un gaz de gonflement, dans une cavité corporelle.
