BIOPSY SITE MARKER APPLIER

摘要

A marker delivery device comprises a marker deployer cannula, a push rod, a biopsy site marker, and a ramped tip. The marker deployer cannula may have a marker exit in communication with an interior lumen of the cannula. The marker exit may comprise a distal end with a ramped surface. The biopsy site marker may be configured with a plurality of edges. The plurality of edges may be configured to engage at least a portion of the interior lumen of the cannula. The ramped tip may comprise a first ramped surface and a second ramped surface, the second ramped surface may align with the ramped surface of the distal end of the marker exit. The push rod may be used to push the biopsy site marker up the ramped tip and through the marker exit.

1. A marker delivery device comprising:
(a) a marker deployer cannula comprising:
(i) a distal end;(ii) a proximal end;(iii) a internal lumen; and(iv) a marker exit comprising a distal end, wherein the distal end comprises a ramped surface;wherein the marker exit is spaced proximal to the distal end, wherein the marker exit is in communication with the internal lumen; (b) a push rod having a distal end, wherein the push rod is slidably disposed within the marker deployer cannula; (c) a biopsy site marker; and (d) a ramped tip, the ramped tip comprising:
(i) a distal tip; and(ii) a ramp having a first ramped surface and a second ramped surface, wherein the ramp extends proximally from the distal tip, wherein the first ramped surface is positioned proximally from, and directly adjacent to, the second ramped surface, wherein the first ramped surface has a first incident angle, wherein the second ramped surface has a second incident angle, wherein the second ramped surface is configured to align with the ramped surface of the distal end of the marker exit;wherein the ramped tip is insertable into the distal end of the marker delployer cannula; wherein the marker delivery device is operable to deploy the biopsy site marker at a biopsy site.
