Abstract:
Methods and devices to facilitate positioning of a catheter into a vessel. Devices include axially concentric assemblies of a piercing needle and a dilator that guides an outer catheter into a vessel, such as a blood vessel. The assemblies described herein can include retraction mechanisms and/or lock mechanisms to control needle positioning during catheterization processes as well as improved valves that prevent leakage of fluid from the proximal end of the devices. The devices and method include the use of novel valves to prevent undesired leakage of fluids through the proximal end of the catheter.

Claim (Index 29):
A catheter assembly for use with a male luer having a distal end and a lateral surface, the male luer having a connector portion, the catheter assembly comprising:\n a catheter hub having a chamber with a proximal surface defining an open proximal end; a catheter tubing coupled the catheter hub and having a lumen in fluid communication with the chamber; a septum valve comprising:\n a barrier layer at a distal end, the barrier layer having at least one slit, \n a wall portion extending proximally from the barrier layer, the wall portion defining a valve cavity therein, \n a flange portion at a proximal end of the septum valve, the flange portion having a diameter greater than a diameter of the wall portion; \n the septum valve is coupled to the catheter hub such that the flange portion engages the proximal surface of the catheter hub exterior to the chamber and the wall portion engages a surface of the chamber; and wherein insertion of the male luer into the cavity of the septum valve causes the distal end of the male luer to open the slit, while the lateral surface of the male luer engages the wall portion within the cavity causing the wall portion to engage an interior surface of the chamber, and where the connector portion engages the flange portion against the proximal surface of the catheter hub.
