Abstract: A biopsy device includes a cutter defining a cutter lumen and a tissue sample holder for collecting tissue samples. In one example, the tissue sample holder has a rotatable manifold that is configured to redirect fluid from one axial direction to an opposite axial direction. The tissue sample holder also has a plurality of tissue sample trays through which fluid may be communicated. The tissue sample trays define chambers that are each configured to separately hold tissue samples. The tissue sample trays are removable relative to the manifold. A cup is configured to cover the manifold and trays. A tissue sample holder rotation mechanism is operable to rotate the manifold to successively index each chamber of the tissue sample trays with the cutter lumen. A feature may prevent rotation of the manifold when one part of the biopsy device is separated from another part of the biopsy device.

Abstract: A locking mechanism which provides a number of resistance points, all of which function to impede the opening of a door located on the chassis of a lottery dispensing machine or any other enclosure that must be secured. The locking mechanism includes a rotating cam which sets the lock in motion. Rotation of the cam is translated into reciprocating motion of a number of bolts which move into a locked position. Once the bolts are in a fully locked position, movement of the door is impeded. If two bolts are used, they face in opposite directions. If more than two bolts are used, they all face in different directions. This makes the lock impossible to jimmy. Further, to successfully pry open the lock would require an effort great enough to cause substantial structural damage to the enclosure itself. A cam extension is also provided which provides extra resistance when the locking mechanism is in a closed position.
