摘要： A marking device (10) according to one embodiment of the invention comprises a handle (14), a cannula (16) having a cannula distal end (180) and slidably mounted to the handle (14), and a stylet having a stylet distal end and slidably mounted to the handle (14) in the cannula (16). The stylet distal end is spaced proximally of the cannula distal end (180) to form a marker recess that receives an imaging marker. The marking device (10) further comprises an actuator (20) operably coupled to the cannula (16) to effect retraction of the cannula (16) into the handle (14) following implantation of the imaging marker. The imaging marker can be implanted by advancing the stylet relative to the cannula (16) to eject the imaging marker from the marker recess, or the cannula (16) can be retracted relative to the stylet to expose the imaging marker.

摘要： A biopsy marking apparatus (10) for placing a radiopaque marker at the location of a percutaneous biopsy. The biopsy marking apparatus comprises an introducer (12) in combination with a radiopaque marker. The introducer (12) ejects the radiopaque marker at the location of the biopsy. The introducer (12) is configured to completely eject the radiopaque marker and prevent if from being subsequently drawn into the introducer (12) as the introducer is removed from the biopsied tissue mass. The radiopaque marker has enhanced radiopaque characteristics and enhanced non-migration characteristics.
