  • Patent number: 10775280
    Abstract: A filtration assembly for separating solids from liquids contained in a sample, and a method for preparing such a sample are disclosed herein. According to one embodiment, the filtration assembly includes an inner element (100) with proximal and distal ends (102,103) and a sample (200) disposed therein. A reinforcing sleeve (300) is disposed around the inner element (100) to form a sample receiver (250) with proximal and distal ends (252,253). A filter (400) is disposed at the open proximal end of the sample receiver (252) and a filtrate receiver (500) is placed over the filter (400) and threadedly engaged with the sample receiver (250) to clamp the filter (400) therebetween. Then, the receivers (250,500) are inverted and a pressure is applied to the sample (200) to force a liquid component (200a) through the filter (400) into the filtrate receiver (500), while solids (200b) are retained in the sample receiver (250).

  • Publication number: 20180156698
    Abstract: A pathologic staging compression device prepares a biological sample for pathologic staging by compressing the sample to remove liquid fat from the sample. In one embodiment, the apparatus preferably includes a compression tube, a removable drainage planum to hold the compression tube, a fat containment and drainage system, a gauge to monitor the extrusion force, use of hydraulic pressure to generation the extrusion force for sample compression, and ejection of the compressed sample after the compression tube has been removed from the drainage planum. In another embodiment, the apparatus includes an integrated riser assembly to stabilize and align the compression tube.
