  • Patent number: 8603048
    Abstract: According to the invention, the spring-effect deformation capacity of the valve (5) essentially relates to the plug (Sa) and to an intermediate valve portion (5c) between the plug (Sa) and a tubular gap (6). The valve (5) and the fixed end piece (3) are conformed so that the valve can be permanently tightened on the fixed end piece without forming a significant dead volume in said gap independently from the deformation of the valve, and so that the valve can be maintained on the fixed end piece (3) without any flexion under the action of the mobile end piece. The slot (9) of the valve includes a moulded proximal slot (9A) followed by a pierced distal slot (9B) for communication between the moulded slot and said gap when the slot is open. Application in medical fluid connectors.

  • Patent number: 8251923
    Abstract: A device for introducing a catheter guide wire into a vessel of a patient has a connector and a straightener for a J-shaped end of the guide wire, the connector having an axial bore, and its distal end and proximal end permitting a connection of the Luer type to a needle and to a syringe, respectively. The connector supports, on its inside, a sealing valve equipped with a slit, and the axial bore has, in its portion between the sealing valve and the distal end of the connector, a leaktight mating surface, the shape of which is such that it permits liquid-tight mating with the outer surface of the distal end of the straightener, when the latter is introduced into the connector via the sealing valve.
