Patent ID: 8329120

Claim:
A histologic tissue sample support device for orienting and retaining tissue samples during processing, embedding and sectioning in a microtome, comprising: a tissue cassette, the tissue cassette including a perforated bottom wall and at least one perforated side wall for defining a tissue sample receiving space, the cassette formed of material which can be successfully sectioned in a microtome and is resistant to degradation from solvents and chemicals used to fix, process and stain tissue, the tissue cassette including first and second elongate channels for receiving at least one tissue sample, the first and second channels being separated from each other by separating structure, the separating structure connected with and extending upwardly from the bottom wall and including an anchoring element including a surface facing the bottom wall to anchor the separating structure in embedding material during a microtome sectioning process; and tissue sample biasing structure configured to extend into the first and second channels to retain the tissue sample or samples against the bottom wall during processing and embedding, the tissue sample biasing structure further being capable of successful sectioning in the microtome.
