Valve assemblies having improved ability to selectively control flow of fluids through the catheter and prevent leakage of fluids from the proximal end of a catheter that is positioned within a patient. Such improved catheter valve assemblies also prevent leakage of fluids after repeated insertion and removal of medical instruments through the valve.

Methods and devices for vascular access

A catheter assembly configured for use with a male luer is provided herein. The catheter assembly can comprise a catheter hub having an interior chamber and a valve located in the interior chamber. The valve can comprise a distal portion, a proximal portion, and a sidewall extending therebetween to define a valve interior. The valve can include a barrier layer having a concave shape that extends in the valve interior from the sidewall at the distal portion. The barrier layer can have at least one slit extending therethrough that is in a normally closed configuration to prevent a fluid from passing through the barrier layer. The catheter assembly can further comprise a sealing ring located circumferentially at a distal end of the valve distally to the barrier layer. The sealing ring can form a seal between the valve and the interior chamber at the distal end.

Methods and devices to facilitate positioning of a catheter into a vessel. Devices include axially concentric assemblies of a piercing cannula, a shield and tubing such as a catheter where the shield can be passively or actively locked into position over the cannula tip to prevent inadvertent needle sticks.
