CA 2368103

A sectional cassette (10) for use in a process for harvesting and handling tissue samples for biopsy analysis is disclosed. In the procedure, a tissue biopsy sample is placed on a tissue trapping supporting material (A') that can withstand tissue preparation procedures, and which can be cut with a microtome. The tissue is immobilized on the material, and the material and the tissue are held in the cassette (10) subjected to a process for replacing tissue fluids with wax. The tissue and supporting material are sliced for mounting on slides using a microtome. Harvesting devices and containers (200) using the filter material (202) are disclosed. An automated process is also disclosed.

L'invention concerne une cassette sectionnée (10) à utiliser lors du prélèvement et de la manipulation d'échantillons tissulaires en vue d'une analyse de biopsie. Selon le procédé, un échantillon tissulaire prélevé est placé sur un matériau de support de piégeage tissulaire (A') capable de supporter les opérations de préparation tissulaire et pouvant être coupé avec un microtome. Le tissu est immobilisé sur le matériau et tous deux sont maintenus dans la cassette (10) où les fluides tissulaires sont remplacés par de la paraffine. Le tissu et le matériau de support sont incisés à l'aide d'un microtome pour être montés sur des plaquettes. Des dispositifs de prélèvement et des conteneurs (200) utilisant le matériau filtrant (202) font aussi l'objet de cette invention. L'invention concerne en outre un procédé automatisé.
