The invention relates to a device for introducing a catheter guide wire (2) into a vessel of a patient, this device comprising a connector (3, 4, 6) and a straightener (1) for the J-shaped end of said guide wire, said connector (3, 4, 6) being traversed by an axial bore (31, 610, 650), and its distal end (65) and proximal end (42) permitting a connection of the Luer type to a needle (8) and to a syringe (7), respectively. This device is characterized in that said connector supports, on its inside, a sealing valve (5) equipped with a slit (53), and in that said axial bore (31, 610, 650) comprises, in its portion situated between said sealing valve and the distal end (65) of the connector, a surface (651) referred to as a "leaktight mating surface", the shape of which is such that it permits liquid-tight mating with the outer surface of the distal end (13) of said straightener (1), when the latter is introduced into said connector (3, 4, 6) via said sealing valve (5).

L'invention concerne un dispositif pour l'introduction d'un fil (2) de guidage d'un cathéter,dans un vaisseau d'un patient, ce dispositif comprenant un connecteur (3, 4, 6) et un redresseur (1) de l'extrémité en J dudit fil de guidage, ledit connecteur (3, 4, 6) étant traversé par un alésage axial (31, 610, 650) et ses extrémités distale (65) et proximale (42) permettant une liaison de type Luer respectivement avec une aiguille (8) et une seringue (7). Ce dispositif est remarquable en ce que ledit connecteur supporte intérieurement une valve d'étanchéité (5) munie d'une fente (53) et en ce que ledit alésage axial (31, 610, 650) comprend dans sa portion située entre ladite valve d'étanchéité et l'extrémité distale (65) du connecteur, une surface (651), dite "d'appariement étanche" dont la forme est telle qu'elle permet un appariement étanche aux liquides avec la surface extérieure de l'extrémité distale (13) dudit redresseur (1), lorsque ce dernier est introduit dans ledit connecteur (3, 4, 6), au travers de ladite valve d'étanchéité (5).
