Abstract

L'invention porte sur un système d'introduction comportant: une aiguille introductrice présentant une extrémité distale, une extrémité distale, ainsi qu'une poignée dont une extrémité reçoit l'aiguille de manière réversible ou non; et un connecteur auquel on fixe la bandelette implant formé par un bras percé d'un orifice longitudinal où l'extrémité de l'aiguille introductrice qui présente un barbillon vient se loger. Ledit connecteur peut en outre présenter une partie centrale, une première et une deuxième extension en partant et un deuxième bras comportant un premier trou et un deuxième trou et monté pivotant sur la partie centrale. Le premier et le deuxième trou peuvent être positionnés pour que quand le premier bras pivote vers le deuxième, la première extension et la deuxième soient reçues dans le premier et le deuxième trou. Une partie du tube s'étendant au delà de ladite partie centrale peut présenter une ouverture permettant de loger le barbillon de manière à ce que le connecteur puisse être soit réversiblement couplé, soit reste fixé en permanence à l'aiguille introductrice.
