The grip may include a face disposed outwardly from the push tab and the ribs. A grip of a user may contact the push tab, the ribs, and the face to reduce rotation between the catheter hub and the needle hub in response to distal advancement of the catheter hub. ## Claims ### Claim 1 A catheter system, comprising: a catheter assembly, comprising: a catheter hub, comprising a distal end, a proximal end, a lumen extending through the distal end and the proximal end, and a stepped or tapered outer surface disposed between the distal end and the proximal end;
