A jetless intravenous catheter for the delivery of a fluid into a peripheral vein of a subject includes an elongated body having proximal and distal ends. The body includes a wall defining an internal fluid passageway configured to receive fluid flowing in a longitudinal direction from the proximal end at a first axial velocity and a tip aperture at the distal end configured to allow fluid to exit therethrough. The body comprises at least one flow reducing feature configured to create a laminar-turbulent transitional flow associated with a fluid flowing in the longitudinal direction at the first axial velocity and configured to reduce the flow velocity of fluid exiting the tip to a second axial velocity that is less than the first axial velocity.
