Abstract: A midline catheter is provided. The midline catheter includes a shaft defining a lumen, the shaft having a distal end and a proximal end. The distal end includes two or more opposing notches thereon, each of the notches having an open notch distal end and an opposing notch proximal end formed as an arch. The catheter may also include written indicia thereon to indicate that it is a midline catheter and/or is power injectable or non-power-injectable.
