Abstract
Catheter devices are described. The catheter devices can have a catheter hub, a needle hub, and a bypass system for controlling fluid flow around a barrier. The bypass system can include flow ports for routing flow around the barrier. A filter can be placed in the path fluid flow in the distal direction to filter out contaminants or other unwanted materials prior to discharging out the catheter tube. A gas permeable membrane can be included to expel gas from the catheter device. A needle guard is usable with the needle device to block a tip of the needle.
