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 15):
A medical assembly comprising:\n an assembly housing having a projection located therein; a first tubular member having a first hub coupled with the assembly housing; a needle having a needle hub, the needle extending through the first tubular member, the needle hub positioned within the assembly housing, the needle hub including a positioned in a fluid path of the needle hub such that fluids passing through the needle into the needle hub engage the stop material; where the needle assembly is actuatable from an unloaded configuration to a loaded configuration during which a distal end of the needle extends beyond a distal end of the first tubular member, where in the unloaded configuration a mechanical stress restrains the needle assembly from moving in a proximal direction without increasing mechanical stress on the stop material wherein in the loaded configuration a biasing element moves the needle hub proximally until the stop material engages the projection increases mechanical stress on the stop material, which prevents further proximal movement of the needle hub; and wherein as fluid from the needle hub contacts the stop material, a structural integrity of the stop material reduces eventually permitting proximal movement of the needle hub such that the distal end of the needle retracts within the first tubular member.
