Patent ID: 7888132

Claim:
A method for processing tissue samples in preparation for histological examination, said method comprising: (A) providing a histological retaining device comprising (i) a foldable liquid permeable sheet having edges with a liquid permeable target disposed within the edges of said liquid permeable sheet, thereby providing extended flap portions which flap portions are foldable to overlap the liquid permeable target, and (ii) a malleable securing strip attached to the foldable liquid permeable sheet of a length sufficient to secure said folded flap portions overlapping said liquid permeable target; (B) creating a tissue preparation system comprising (i) placing a tissue sample on the liquid permeable target of said histological retaining device, (ii) folding the flap portions to overlap the liquid permeable target containing the liquid permeable tissue sample; (iii) crimping the malleable securing strip by bending the malleable securing strip around the folded flap portions to clamp the folded flap portions to the liquid permeable target; and (C) processing the tissue preparation system for histological examination in known ways, including passing liquid through the foldable liquid permeable sheet.
