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.

2. The tissue handling system of claim 1, further comprising a vessel configured to couple to the tissue storage container, the vessel configured to contain a preserving agent for delivery to the tissue storage container.

3. The tissue handling system of claim 1, further comprising a vessel that contains a preserving agent, the vessel configured as a lid to couple to the tissue collecting device and configured to seal against the tissue storage container and release the preserving agent into the tissue storage container.

4. The tissue handling system of claim 1, further comprising a vessel that contains a preserving agent, wherein the tissue storage container and the vessel comprise a connecting structure for gas-tightly connecting the vessel to the tissue storage container, and wherein the preserving agent is released as a consequence of the connecting of the vessel to the tissue storage container.

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

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

7. A tissue handling system, comprising:

a biopsy device having a housing with a housing cavity, an invasive unit with tissue-receiving components, and tissue-severing components configured for harvesting and bringing at least one tissue sample to a point outside the body of a patient;

a tissue collecting device configured to be removably mounted to the biopsy device and configured for detachable operative engagement with the tissue-receiving components of the biopsy device, the tissue collecting device having a collecting unit configured to be mounted in the housing cavity of the biopsy device and configured to receive the at least one tissue sample during a biopsy procedure; and

a tissue storage container separate from the biopsy device configured to removably mount the tissue collecting device after the tissue collecting device is removed from the biopsy device following the biopsy procedure, the tissue storage container having a trough configured to receive therein the collecting unit of the tissue collecting device that contains the at least one tissue sample.

8. The tissue handling system of claim 7, wherein the collecting unit 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 store the tissue samples in respective individual tissue chambers.

9. The tissue handling system of claim 7, wherein the collecting unit includes a chamber, 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 tissues samples as they are excised from the body of the patient and temporarily store the tissue samples in one single bulk in said chamber.

10. The tissue handling system of claim 7, wherein the biopsy device comprises a disposable unit, the tissue collecting device is configured for operative engagement with the disposable unit, and the tissue collecting device is stepwise rotatable about a central axis.

11. The tissue handling system of claim 7, further comprising a vessel configured for coupling to be the tissue storage container, the vessel configured to contain a preserving agent for delivery to the tissue storage container.

12. The tissue handling system of claim 7, comprising a vessel adapted to contain a preserving agent and configured to be coupled to the tissue storage container to facilitate transfer of the preserving agent to the trough of the tissue storage container.

13. The tissue handling system of claim 12, comprising:

a disk positioned over the trough of the tissue storage container, the disk having a plurality of holes; and

wherein the vessel is a storage container lid configured for connection to the tissue collecting device, the storage container lid having a plurality of apertures, and the storage container lid has a compartment for storing the preserving agent, and

wherein the compartment is closed by a liquid and gas tight closure when the storage container lid is coupled to the tissue storage container and the plurality of apertures and the plurality of holes are not in alignment, said closure being configured to be released when the storage container lid is rotated relative to the tissue storage container to align the plurality of apertures and the plurality of holes.

14. The tissue handling system of claim 12, wherein the tissue storage container and the vessel comprise a connecting structure for gas-tightly mating the vessel to the tissue storage container, and wherein the connecting structure is configured to facilitate release of the preserving agent as a consequence of rotating the vessel relative to the tissue storage container.

15. The tissue handling system of claim 12, wherein the vessel is comprised in a lid configured to couple to the tissue collecting device and configured to close the tissue storage container and suspend the collecting unit in the trough.

16. The tissue handling system of claim 15, wherein the lid is configured for attachment 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 facilitates release of the preserving agent, the tissue storage container and the lid being arranged such that the second attachment action cannot occur prior to the first attachment action.

17. The tissue handling system of claim 12, wherein the vessel has a compartment for storing the preserving agent, and wherein the compartment is closed by a liquid and gas tight closure, said closure being releasable when the vessel is mated or coupled to the tissue storage container.

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