Ported IV catheter having external needle shield and internal blood control septum

An extravascular system for accessing the vasculature of a patient, comprising:

• a catheter adapter having a distal end, a proximal opening and a lumen disposed therebetween, the distal end supporting a catheter;
• an access port coupled to an outer surface of the catheter adapter and having an inner lumen that is in fluid communication with the lumen of the catheter adapter;
• a blood control valve disposed within the lumen of the catheter adapter and dividing the lumen of the catheter adapter into a proximal fluid chamber and a distal fluid chamber;
• a plurality of grooves forming air channels disposed on an outer surface of the valve and/or on an inner surface of the lumen of the catheter adapter;
• a defeatable barrier disposed within the lumen of the catheter adapter and selectively forming a sealed interface with the inner lumen of the access port;
• an activator having a base and a probe end, the activator being movably positioned within the proximal fluid chamber;
• and
• a housing comprising a distal end and a proximal end;
• wherein
• an outer surface of the catheter adapter is disposed within the distal end of the housing;
• and
• the distal end of the housing extends distal to the base of the activator when the activator is in initial position.
