Abstract

A subcutaneous marking apparatus for placement of an imaging marker at a predetermined site in a tissue mass comprises a handle having a front portion and a rear portion, a cannula, a stylet slidably received within the cannula, a trigger extending from the front portion of the handle and operably engaging the stylet, and an imaging marker disposed within a marker recess in a distal end of the cannula. A user can firmly grasp the marking apparatus in one hand and simultaneously actuate the trigger with a finger or a thumb of the same hand to move the stylet and thereby place the imaging marker at the predetermined site.
