Patent ID: 6913921

Claim:
A flow-through cell block embedding apparatus, comprising: a sample port; a cell flow pathway defined by an inflow tube that is adapted to be coupled to the sample port, wherein the inflow tube is effective to deliver cell fragments from a cell sample to the sample port; a tissue cassette in fluid communication with the sample port, the tissue cssette including a removeable and replacable filter such that upon the application of pressure, the cell fragments are drawn from the cell sample through the inflow tube to the sample port and deposited onto the filter; a reagent port in fluid communication with the sample port; and a plurality of reagent delivery tubes adapted to be coupled in fluid communication to the reagent port, wherein the plurality of reagent tubes are effective to deliver a plurality of reagents to the reagent port such that upon the application of pressure, the reagents are drawn through the reagent delivery tubes to the reagent port to the deposited cell fragments on the filter.
