Abstract: A needle assembly has a needle having an echogenic feature proximate to its distal sharp tip mounted to an echogenic cannula, with the echogenic tip of the needle extending beyond the distal end of the cannula. The echogenic tip provides guidance for the movement of the needle assembly under ultrasound observation so that the needle assembly may be more readily maneuvered inside a body.
