The device () for selective access closure inside a catheter comprises a conduit () having a rear extremity () for the insertion of a medical instrument and a mechanism () for adjusting the cross-section provided within the conduit (). The mechanism () comprises a member () for repositioning the device between an opening movement and a closing movement. The direction of movement of the repositioning member () along both the closing path and the opening path are identical.

The inflation device comprises a syringe whose piston presents a thread. It further comprises a retaining mechanism for retaining the piston and comprising two half-nuts movable between a position in which they are spaced apart from the thread and a position in which they engage the thread, together with control members mounted to tilt relative to the syringe body. For each half-nut, the retaining mechanism comprises two resilient tabs pressing against the corresponding half-nut and against the syringe body. In addition, each of the control members comprises a finger pressing against the corresponding half-nut and adapted, when the member tilts, to press against one of two bearing surfaces carried by the half-nut and offset relative to each other in a radial direction of the syringe body.

This distribution device comprises a syringe body (), a distributor (), a feed tube () for a first active medical fluid opening into the syringe body (), a tube () for the injection of this active fluid connected to a distal extremity () of the syringe body (), a pressurized tube () designed to be connected to a patient through a pressurized line () and a tube () for the measurement of venous or arterial pressure. The pressurized, injection and measurement tubes open into a chamber () bounded within the body (B) of the distributor (). The device () comprises a flush tube () which is at least partly bounded by the body (B) of the distributor (), which opens into the chamber () and is fitted with a valve () which can be operated manually.

The injection syringe has at least one syringe body () provided with a needle () and a pusher () mounted so as to be able to move in the body (). The syringe has a movable guard () for protecting the injection end (A) of the needle. The guard () is able to move with respect to the body () between a position retracted in the body () and an active protection position. The guard () and the body () have associated projecting and recessed reliefs for holding the guard in a retracted position. It has a retractable member () for positive holding of the engagement of the said associated reliefs, when the guard () is in a retracted position. The pusher () and the said holding member () are adapted for a retraction of the said holding member () under the action of the pushing in of the pusher () into the body, at the end of injection, providing a release of the positive holding of the engagement of the associated reliefs.
