1. A tissue sample holder for collecting tissue samples obtained using a biopsy device, wherein the biopsy device has a cutter extending distally from the biopsy device and defining a cutter lumen along an axis, wherein the tissue sample holder comprises:

  • (a) a rotatable manifold, wherein the manifold is in fluid communication with a conduit, wherein the manifold is configured to redirect fluid, wherein the manifold is configured to communicate a vacuum from the conduit to the cutter lumen, wherein the rotatable manifold comprises one or more distal openings on a distal end of the rotatable manifold, wherein the vacuum is communicated from the conduit, through at least one of the distal openings, and to the cutter lumen only through the distal end of the rotatable manifold;

    (b) a plurality of discrete tissue sample chambers associated with the manifold, wherein each distal opening of the rotatable manifold is substantially parallel to and in communication with an associated one or more of the discrete tissue sample chambers, wherein each of the tissue sample chambers is configured to receive at least one tissue sample communicated through the cutter lumen;

    (c) a cover member configured to removably cover the manifold and the tissue sample chambers, wherein the manifold and tissue sample chambers are configured to rotate within the cover member; and

    (d) a tissue sample holder rotation mechanism, wherein the tissue sample holder rotation mechanism is operable to rotate the manifold to successively index the tissue sample chambers relative to the cutter lumen.
