Applier for implantable surgical marker
First Claim
1. An applier for initially delivering a biopsy marker to a surgical biopsy site and subsequently deploying said marker at the site, said applier comprising:
- a) an elongated flexible tube having a distal end;
b) a ferrule fixed to the distal end of said flexible tube, said ferrule having a forming surface thereon adapted to reconfigure said biopsy marker from an original open configuration to a closed configuration when said biopsy marker has been delivered to the surgical site;
c) a marker holder at said ferrule for holding said biopsy marker at the distal end of said flexible tube in the original open position;
d) an elongated forming rod located in said flexible tube, said forming rod adapted to urge said biopsy marker into reconfiguring contact with said forming surface of said ferrule, said forming rod slidable in said flexible tube from an unactuated position wherein said biopsy marker is in the original open position to an actuated position wherein said biopsy marker has been reconfigured in the closed position;
e) an egress tube for receiving the distal end of said elongated flexible tube, said egress tube adapted for delivery through a biopsy cannula wherein said cannula has a biopsy port at a distal end thereof for positioning at the surgical biopsy site to take a biopsy sample, said egress tube having proximal and distal ends, said egress tube having an egress opening at the distal end of said egress tube and an alignment hub at the proximal end of said egress tube, said alignment hub adapted for orientational alignment with a hub receiver on said biopsy cannula so as to align said egress opening of said egress tube with said biopsy port of said biopsy cannula.

Abstract
An applier for delivering and deploying a biopsy marker to a surgical biopsy site is disclosed. The applier has a ferrule with a forming surface to form the marker on the distal end of a flexible tube. The marker is held at the distal end of the flexible tube in a marker holder. A forming rod slidable in the flexible tube urges the marker into contact with the forming surface of the ferrule for marker formation. The distal end of the flexible tube is delivered through an egress tube, which in turn is delivered through a biopsy cannula adapted for taking the biopsy sample. The egress tube has an alignment hub at its proximal end adapted for orientational alignment with a hub receiver on the biopsy cannula. When properly aligned, the egress opening of the distal end of the egress tube is orientationally aligned with the biopsy port of the biopsy cannula for proper delivery and deployment of the marker.
