Publication number: 20240001083Abstract: 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.Type: ApplicationFiled: August 29, 2022Publication date: January 4, 2024Applicant: I-V Access Technology, Inc.Inventors: Thomas SUTTON, Joe RANALLETA, Nicholas Hogan MININNI, Kevin JOHNSON
