Echogenic needle

There is provided a needle for viewing under ultrasound imaging. The needle comprises a shaft extending along a longitudinal axis having a proximal end and a distal end including a sharp tip, one groove formed spirally from at least adjacent the sharp tip a predetermined distance along the shaft away from the sharp tip, the one groove being tilted from a neutral position to a tilt angle position toward the proximal end of the shaft so that an ultrasound wave from an ultrasound transducer directed to the shaft is reflected in a substantially reverse direction back to the transducer by at least a wall of the one groove when the shaft is positioned at an insertion angle for insertion into a subject.
