Catheter devices with pliable catheter hubs and related methods

A catheter assembly, comprising:

• a catheter hub having a hub body, an opening at a proximal end, and an interior cavity defined by the hub body;
• a catheter tube extending distally from the catheter hub and communicating with the interior cavity of the catheter hub;
• an outer casing positioned over the proximal end and at least part of the hub body of the catheter hub, said outer casing having an interior cavity and a septum at or near a proximal end;
• a needle hub removably coupled at the proximal end of the catheter hub such that part of the outer casing is wedged between the needle hub and the catheter hub, the needle hub having interior proximal cavity and a distal cavity;
• and
• a needle projecting distally from the needle hub through the septum of the outer casing and having a needle tip extending out a distal opening of the catheter tube in a ready to use position.
