Abstract
A surgical needle having notches in a sidewall with enhanced ultrasound reflectivity is disclosed. Indentations, ridges, projections, overhanging edges, and other structures are formed in the notches to retain small amounts of air or other reflective material as the surgical needle is passed through tissue. The additional amounts of reflective material retained by these structures will significantly enhance the ultrasound reflectivity and enhance the response to ultrasonic probing to provide an enhanced image during needle placement in a medical patient so that the needle may be accurately placed as desired. Alternatively or additionally, the notches are filled with a substance that contains air bubbles suspended in the substance wherein the suspended air bubbles provide the reflectivity enhancement. In both embodiments, the needle will be visible at any angle in which the device is used in a medical patient.
