Abstract
A marking assembly includes a hollow cannula having a wall extending from a proximal end to a distal end. The wall defines a lumen of the cannula. The wall includes at least one opening at a distal portion of the cannula. A stylet is configured to be received in the lumen of the cannula. The stylet has a wall extending from a proximal end to a distal end. When the stylet is received in the lumen of the cannula, a circumferential space is defined between the wall of the stylet and the wall of the cannula such that fluid entering the circumferential space will exit the cannula through the at least one opening of the cannula.
