Zusammenfassung:A biopsy device comprises a probe body, a needle portion, a hollow cutter, and a tissue sample holder. The needle portion extends distally from the probe body and comprises a transverse tissue receiving aperture. The hollow cutter is translatable relative to the needle portion to sever a tissue sample from tissue protruding though the aperture. The hollow cutter defines a cutter lumen. The tissue sample holder comprises a body and a tissue sample tray. The tissue sample tray is removably engaged with the body and comprises a downwardly extending lumen. The downwardly extending lumen includes a pair of lower openings which are in communication with a chamber defined by the tissue sample tray.
