The present disclosure is directed to an expandable sleeve for a catheter assembly. The expandable sleeve includes a body configured to fit coaxially around an outer diameter of a catheter of the catheter assembly at a transition location between a hub and the catheter. Further, the body of the sleeve includes a length extending from a first end to a second end. As such, the sleeve is expandable between a compressed position and an expanded position so as to prevent the catheter from collapsing along the length of the sleeve. In addition, when in the expanded position, at least a portion of an interior surface of the sleeve contacts an outer diameter of the catheter.
