    摘要： 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.

    摘要： A marking apparatus includes a rigid cannula having a peripheral wall forming a lumen that carries an imaging marker, a proximal end coupled to a handle, a lateral opening in the peripheral wall that is open to the lumen, and a closed-off distal portion having a ramp adjacent the lumen. The closed-off distal portion extends distally from the ramp to terminate at a tissue piercing pointed tip. The ramp of the rigid cannula is curved to transition from the peripheral wall of the rigid cannula to the lateral opening of the rigid cannula. The ramp of the rigid cannula is adapted to engage the distal end of the stylet as the stylet is advanced through the lumen of the rigid cannula to guide the distal end of the stylet to a position to substantially close off the lateral opening of the rigid cannula having the tissue piercing tip.

    摘要： A delivery apparatus for the percutaneous placement of a medical device at an area of interest in a tissue mass comprises an introducer comprising a cannula having an insertion tip, an expulsion opening near the insertion tip, and a medical device within the cannula comprising an imaging element, and a guide element connected to the imaging element and having a separable portion, and wherein the cannula is inserted into the tissue mass such that the medical device can be expelled through the expulsion opening into the tissue mass, and when the cannula is withdrawn from the tissue mass, the imaging element is placed within the tissue mass at the area of interest, and at least part of the guide element extends exteriorly of the tissue mass, and when the separable portion is separated from the guide element, no part of the guide element extends exteriorly of the tissue mass.
