Catheter hub and strain relief

A method comprising:

• positioning a proximal end of a catheter body adjacent to a distal end of a hub, wherein the hub defines a hub lumen extending along a longitudinal axis of the hub from a proximal portion of the hub to the distal portion, wherein an outer surface of the distal portion of the hub tapers inwardly toward the longitudinal axis as the distal portion extends distally;
• sliding a strain relief proximally over the catheter body via a strain relief lumen, wherein the strain relief comprises a distal portion and a proximal portion configured to receive the distal portion of the hub within the strain relief;
• and
• securing the strain relief to the hub by at least sliding the proximal portion of the strain relief over the distal portion of the hub, wherein the strain relief lumen substantially aligns with the hub lumen upon the strain relief being secured to the hub, wherein both an outer surface of the strain relief and an outer surface of a medial portion of the hub define a substantially similar distance to the longitudinal axis along an interface between the outer surface of the strain relief and the outer surface of the medial portion of the hub.
