Device for introducing a catheter guide wire into a vessel
First Claim
1. A device for introducing a wire with a J-shaped end, into a blood or lymph vessel of a patient, said wire being used for guiding a catheter, wherein said device comprises a connector and a straightener of the J-shaped end of said guide wire, said connector comprising a body with an axial bore which extends between a distal end and a proximal end of said body, said distal end adapted for providing a Luer type connection with a base of a needle and said proximal end providing a Luer type connection with a distal end of a syringe, wherein said connector further comprises a sealing valve provided with a slit intersecting an axis of said axial bore and said axial bore has a portion between said sealing valve and the distal end of the connector adapted to receive a distal end of the straightener, wherein said portion has a mating surface in leaktight engagement with an outer surface of the distal end of said straightener, when said straightener is disposed within said sealing valve.

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.
