ABSTRACT:
Transverse notches in a surgical needle provide an increased reflecting area and enhanced response to ultrasonic probing to provide an enhanced image on an ultrasonic echo sensor. Having the notch cut through to the needle lumen entrains small air bubbles in the notch further enhancing ultrasonic reflection and ultimate imaging of the needle's position.
