Abstract: Aspects of the present disclosure include catheter devices in which a bushing is disposed in an interior cavity of a catheter hub. The bushing has a flexible portion extending out a distal end of the catheter hub. A catheter tube is sleeved over the flexible portion. A needle hub with a needle projects through the flexible portion of the bushing and the catheter tube. The flexible portion is bendable to form at least one curve along the flexible portion. The at least one curve has a minimum bend radius when a first surface of the flexible portion is extended and a second surface opposite the first surface of the flexible portion is shortened.

Abstract: Valves are described for intravenous (IV) catheter assemblies for controlling fluidic flow. The valve can prevent blood leakage in multiple access use situations. A thinner area of the valve around a slit is provided. The thicker area of the valve is to provide rigidity to the valve so that it is able to return to a closed configuration when a Luer connector is removed.

Abstract: An intravenous catheter device or apparatus includes a catheter hub, a catheter tube that resists kinking, a needle, and a needle hub. The catheter tube includes a catheter body having a lumen, an. outer circumference, and a wail thickness between the lumen and the outer circumference, or between an exterior surface and an interior surface. The catheter body can have at least two different portions made from two different materials having two different stiffness properties. The first portion can be made from a first material and the second portion can be made from a second material and wherein the stiffness of the second material can be greater than the stiffness of the first material.
