The current application relates to infusion devices, specifically to peripheral intravenous (IV) catheters. In particular, the application relates to peripheral IV catheter assemblies having features to enable selective and reversible activation of fluid flow through the catheter assembly. Disclosed are integrated septum and septum actuators, systems for controlling fluid flow in a catheter assembly and methods of manufacturing the same. The integrated septum and septum actuator has a base having a fluid pathway and an extension arm extending outwardly from the base. The extension arm being coupled to a septum. The septum being deformable from a relaxed position to a stressed position. The stressed position biases the septum to provide a pathway around an outer surface of the septum. La présente invention concerne des dispositifs de perfusion, en particulier des cathéters (14) périphériques intraveineux (IV). Plus particulièrement, la présente invention concerne des ensembles cathéters IV périphériques comprenant des éléments caractéristiques permettant d'activer de manière sélective et réversible la circulation du fluide à travers l'ensemble cathéter. Certains modes de réalisation comprennent diverses configurations de valves pour septums (50) ayant une surface barrière (52) qui sont sollicitées pour faire pencher la surface barrière et fournir une voie de passage à travers la valve pour septum.
