Apparatus for the percutaneous marking of a lesion

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.
