Abstract

A cassette for transporting tissue including a first flat reference porous structure for supporting the tissue, and a second porous structure having a compression resistance. The first flat reference porous structure and the second porous structure can be positioned into an abutting, contacting or non-contacting position for securing the tissue therebetween.

Claims

1. A cassette for holding tissue comprising:

a first flat reference porous structure for supporting the tissue;

a second perforated structure defining an interior area containing a second porous structure having a compression resistance;

wherein the first flat reference porous structure and the second porous structure can be positioned into an abutting position for securing the tissue therebetween.

2. The cassette of claim 1 further comprising a first perforated structure defining an interior area containing the first flat reference porous structure having a second compression resistance.

3. The cassette of claim 1 wherein a connector connects said first flat reference porous structure and said second perforated structure and compresses said structures together to firmly trap the tissue therebetween.

4. The cassette of claim 3 wherein said connector connects said first flat reference porous structure and said second perforated structure using a clasp and a hinge.

5. The cassette of claim 1 wherein said second porous structure includes foam to provide a predetermined compression resistance.

6. The cassette of claim 1 wherein said second porous structure include a non-artifact inducing porous membrane.

7. The cassette of claim 1 wherein the compression resistance of the first flat reference porous structure is greater than the compression resistance of the second porous structure.

8. The cassette of claim 1 wherein the first flat reference porous structure and said second perforated structure are arranged to form a clam shell type configuration.

9. The cassette of claim 1 wherein one of the porous structures has a landmark indication system inscribed thereon.

10. A method for holding a tissue sample, comprising:

placing the biopsy sample into a tissue cassette; and

moving at least a portion of the tissue cassette to apply a compressive force to flatten the biopsy sample against a flat reference surface of the tissue cassette.

11. The method of claim 10 wherein the tissue sample is placed into the tissue cassette on a landmark indication system corresponding to a location of harvest of the tissue sample.

12. The method of claim 11 further including marking a label on the landmark indication system corresponding to the location or orientation of harvest of the tissue sample from the patient.

13. The method of claim 10 wherein moving the tissue cassette occurs by rotating a portion of the tissue cassette around a pivot.

14. The method of claim 10 further comprising:

flattening the tissue sample between the flat reference surface and a compressive, porous structure.

15. A cassette for holding tissue comprising:

a first flat reference porous structure for supporting the tissue;

a second porous structure having a compression resistance;

wherein the first flat reference porous structure and the second porous structure can be positioned into an abutting position for securing the tissue therebetween.
