Abstract

A tissue handling system includes a biopsy device having an invasive unit with tissue-receiving and tissue-severing components being capable of harvesting and bringing at least one tissue sample to a point outside the body of a patient. The tissue handling system further includes a tissue collecting device adapted to be brought in detachable operative engagement with the tissue-receiving components of the biopsy device to remove the at least one tissue sample. Additionally, the tissue handling device comprises a tissue storage container configured to receive the at least one tissue sample, the entire tissue collecting device, or the part of the collecting device that contains the at least one tissue sample. The tissue storage container further is configured to receive a volume of preserving agent. The tissue handling system also comprises a vessel including the preserving agent adapted to be gas-tightly mated or coupled to the tissue storage container.

4. A system according to claim 1, wherein the vessel is comprised in a lid for closing the tissue storage container.

5. A system according to claim 4, wherein the lid is attachable to the tissue storage container in such a way that a first attachment action establishes a gas tight coupling of the vessel to the tissue storage container, and a second attachment action causes release of said closure, the tissue storage container and the lid being arranged such that the second attachment action cannot occur prior to the first attachment action.

6. A system according to claim 1, wherein the vessel includes a syringe, and wherein the tissue storage container comprises a connecting mechanism for gas-tightly coupling the syringe to the tissue storage container.

7. A system according to claim 1, wherein the tissue collecting device comprises a collecting unit which comprises a plurality of individual tissue chambers, and wherein the tissue collecting device is configured to facilitate sequentially removing, from the tissue-receiving components of the biopsy device, a plurality of individual tissue samples as they are excised from the body of the patient and temporarily storing the tissue samples in individual tissue chambers.

8. A system according to claim 1, wherein the collecting device comprises a collecting unit, which comprises a chamber, and wherein the collecting device is configured to facilitate sequentially removing, from the tissue-receiving components of the biopsy device, a plurality of individual tissues samples as they are excised from the body of the patient and temporarily storing the tissue samples in one single bulk in said chamber.

9. A system according to claim 1, wherein the vessel is adapted to contain a volume of preserving agent, which is sufficient to cover the at least one tissue sample when stored in the tissue storage container.

25. The tissue handling system of claim 1, wherein the tissue storage container is configured to receive the entire tissue collecting device.

26. The tissue handling system of claim 1, wherein the tissue storage container is configured to receive a part of the collecting device that contains the at least one tissue sample.

27. The tissue handling system of claim 1, wherein the biopsy device comprises a disposable unit, the tissue collecting device being configured for operative engagement with the disposable unit, the tissue collecting device being stepwise rotatable about a central axis.

28. The tissue handling system of claim 27, wherein the tissue collecting device includes a plurality of individual tissue chambers, and wherein the tissue collecting device is configured to facilitate sequentially removing, from the tissue-receiving components of the biopsy device, a plurality of individual tissue samples as they are excised from the body of the patient and temporarily storing the tissue samples in individual tissue chambers.

10. A method of handling at least one tissue sample harvested during a biopsy procedure, the method comprising:

providing the at least one tissue sample in tissue-receiving components of a biopsy device outside the body of a patient;

detachably engaging a tissue collecting device to said tissue-receiving components;

arranging at least one of a tissue sample, the entire tissue collecting device, and the part of the collecting device that contains the at least one tissue sample in a tissue storage container;

gas-tightly coupling a vessel containing a volume of a preserving agent to the tissue storage container; and

transferring the volume of preserving agent from the vessel to the tissue storage container, when the vessel is gas-tightly coupled to the tissue storage container.

11. A method according to claim 10, wherein the vessel has a compartment for storing the preserving agent, and wherein the compartment is closed by a liquid and gas tight closure, and wherein said closure is released from a closed condition to an open condition, when the vessel is mated to the tissue storage container.

12. A method according to claim 11, wherein said closure is caused to be released as a consequence of mating the vessel to the tissue storage container.

13. A method according to claim 12, wherein the vessel is comprised in a lid for closing the tissue storage container, and wherein the lid is attached to the tissue storage container in such a way that a first attachment action establishes a gas tight coupling of the vessel to the tissue storage container, and a second subsequent attachment action causes release of said closure.
