Abstract: An intravenous (IV) catheter assembly may include a catheter adapter and a catheter extending from the distal end of the catheter adapter. The intravenous (IV) catheter assembly may include an introducer needle. The elongated shaft may include a flashback notch, and the flashback notch may include a distal end and a proximal end. The flashback notch may include a smooth tapered edge extending from the distal end in a direction that increases a depth of the flashback notch. The smooth tapered edge may extend along at least half of an entire length of the flashback notch between the distal end and the proximal end. In an orthogonal side view projection of the intravenous catheter assembly, every tangent to the smooth tapered edge may be at an angle of 30° or less with respect to a longitudinal axis of the introducer needle
