A catheter assembly may include a catheter adapter, which may include a distal end, a proximal end, and a lumen extending through the distal end of the catheter adapter and the proximal end of the catheter adapter. The catheter assembly may include a catheter extending distally from the distal end of the catheter adapter. The catheter assembly may include an introducer needle extending through the catheter. An anti-thrombogenic material may be extruded through a die and/or molded to form one or more portions of the catheter assembly. Additionally or alternatively, inner surfaces and/or outer surfaces of one or more portions of the catheter assembly may be coated with an anti-thrombogenic coating that includes the anti-thrombogenic material.
