The introducer assembly (10) includes a base (12) formed of a semi-rigid, flexible or semi-flexible material having an instrument receiving passage (18) extending there through, and further including an exterior sealing (40) surface extending between proximal and distal portions of the base (12). The sealing (40) surface has a predetermined configuration which is shaped to conform to the shape of the entry site as the base passes into the entry site. A fluid restricting seal is established between the exterior of the base and the peripheral tissue surrounding the enry site. A fluid restricting seal is established between the exterior of the base and the peripheral tissue surrounding the entry site, particularly when the enry site is formed by an incision commonly utilized an open laparoscopic procedure.
L'invention concerne un assemblage structuré destiné à introduire un trocart ou un autre instrument médical dans une cavité corporelle via un site d'entrée formé dans la paroi de la cavité. L'assemblage introducteur comprend une base formée d'un matériau semi-rigide, flexible et/ou semi-flexible comportant, dans sa longueur, un passage pouvant recevoir un instrument et comportant aussi une surface d'étanchéité qui s'étend entre les portions distale et proximale de la base. La surface d'étanchéité possède un configuration déterminée qui s'adapte à la conformation du site d'entrée lorsque la base passe dans ce site. Un joint étanche aux fluides est ainsi établi entre l'extérieur de la base et le tissu périphérique entourant le site d'entrée, en particulier lorsque le site d'entrée est constitué de l'incision habituellement pratiquée dans une procédure de laparoscopie.
