Abstract
An epidural needle through which an epidural catheter may be threaded for administering liquid anesthesia into the epidural space, the needle having a curved distal end, the tip of the needle distal to the opening in the needle shaft being substantially planar at an angle of 80.degree.-100.degree. relative to the curved longitudinal axis of the needle shaft, the needle tip being characterized as being faceted so as to retard inadvertent passage of the needle tip through the dura mater of a patient while at the same time retaining the sharp cutting edges common to a like epidural needle which has not had its tip so treated.
