Abstract
A catheter insertion assembly for inserting a catheter into a body lumen of a patient is disclosed as well as a method of using the assembly. The assembly comprises a hub, a catheter stiffener and a valve. The valve is disposed in the lumen of the hub and prevents substantially all fluid flow through the lumen in at least one direction below a pressure threshold. The proximal end of the stiffener is attached to the hub and the stiffener extends distally of the distal end of the hub. The stiffener lumen is in fluid communication with the hub lumen. The stiffener occupies a lumen of the catheter and provides additional stiffness to the catheter such that a catheter introducer is not necessary for insertion of the catheter.
