## Abstract

A tissue acquisition and handling system includes a biopsy device, a tray, and a container. The biopsy device includes a needle and a tissue sample holder assembly. The needle is configured to acquire tissue samples and communicate tissue samples to the tissue sample holder assembly. The tray includes a plurality of strips. The tray is configured to be receiving within the tissue sample holder assembly of the biopsy device. The container includes a plurality of tray receiving portions. Each tray receiving portion includes a distal end, a proximal end, and a tray chamber, the tray chamber extends between the proximal end and the distal end. The tray chamber is configured to receive at least a portion of the tray through a tray opening of the proximal end.

## Claims

### Claim 1

A container for use with a tissue sample tray, the tissue sample tray having a plurality of strips that are configured to receive a tissue sample, the container comprising:
(a) a container body; and
(b) a plurality of tray receiving portions, each tray receiving portion including:
(i) a distal end,
(ii) a proximal end, and
(iii) a plurality of walls;
the distal end, the proximal end, plurality of walls all defining a pair of tray chambers, each tray chamber being configured to receive a strip of the plurality of strips of the sample tray,
at least one of the distal end, or one or more of the plurality of walls defining a plurality of vent openings, the plurality of vent openings being configured to communicate a fixation agent from an exterior of the container and at least one tray chamber of the pair of tray chambers to fix at least one tissue sample, the plurality of walls being configured to surround each strip of the plurality of strips of the sample tray to maintain the at least one tissue sample within a respective tray chamber, and
the plurality of tray receiving portions being defined by the container body along a common plane.

### Claim 2 (depends on 1)

The container of claim 1, the plurality of walls including a top, and a floor, the at least one of the top or the floor defining the plurality of vent openings.

### Claim 3 (depends on 2)

The container of claim 2, the plurality of walls further including a central wall disposed between a pair of sidewalk, the central wall being disposed relative to each vent opening such that each vent opening is in communication with both tray chambers of the pair of tray chambers.

### Claim 4 (depends on 1)

The container of claim 1, the distal end of each tray receiving portion defining at least some of the vent openings of the plurality of vent openings, the vent openings being defined by the distal end including a circular shape.
