Amniopunch and uses thereof
View Patent ↗A tissue, such as an amniotic or chorionic membrane, harvesting device that integrates a system facilitating subsequent storage of tissue samples. The device cuts a sample of the target tissue and automatically deposits the sample in a storage vessel. A method of collecting and storing a sample from a target tissue using a tissue harvesting device. A kit for collecting and storing samples of the target tissue.
1. A device for sampling an amniotic membrane or chorionic membrane, the device comprising:
a first arm;
a second arm connected to the first arm;
a first handle connected to the first arm;
a second handle connected to the second arm;
a cutting element connected to the first arm;
a storage vessel connected to the second arm; and
a tissue support member connected to and covering an end of the storage vessel;
wherein:
at least one of the first and second arms is moveable between an open position of the device and a closed position of the device; and
when the device is transitioned from the open position to the closed position,
the cutting element cuts both a biological material comprising an amniotic membrane or chorionic membrane positioned between the first arm and the second arm and the tissue support member; and
the cutting element deposits both the cut biological material and the cut tissue support member into the vessel.
2. The device of claim 1 wherein the storage vessel is removably connected to the second arm.
3. The device of claim 1 wherein the cutting element and the storage vessel are coaxially aligned when the device is in the closed position.
4. The device of claim 1 wherein the storage vessel is a sealable storage vessel, and wherein the device seals the storage vessel after the cut biological sample and tissue support member are deposited into the vessel.
5. The device of claim 1 further comprising a cap for sealing the storage vessel.
6. The device of claim 5 wherein the cutting element is integral with one of the following:
the storage vessel; and
the cap.
7. The device of claim 1 wherein the storage vessel holds a biological medium and the tissue support member retains the biological medium within the storage vessel.
8. The device of claim 1 , further comprising a cassette connected to one of the first and second arms, wherein the cassette comprises at least one of the following:
a cap;
the storage vessel; and
the cutting element.
9. The device of claim 8 wherein the cassette further comprises additional storage vessels and corresponding additional cutting elements; and closing the device automatically advances the cassette.
10. The device of claim 9 wherein the cassette comprises a linear array of storage vessels or a circular or semicircular array of storage vessels.
11. The device of claim 8 wherein the cassette comprises the cutting element and the storage vessel.
12. The device of claim 8 wherein the cassette comprises the cap and the cutting element.
13. The device of claim 1 wherein the cutting element comprises a plurality of cutting elements and the storage vessel comprises a corresponding plurality of storage vessels, wherein closing the device results in cutting of a plurality of samples of the biological material and tissue support member by the plurality of cutting elements, and deposition of the plurality of samples and tissue support member in the corresponding plurality of storage vessels.
14. The device of claim 1 wherein the storage vessel comprises a tracking device selected from the group consisting of a barcode and a radio frequency identification tag.
15. A method of sampling an amniotic membrane or chorionic membrane comprising:
positioning a biological material comprising an amniotic membrane or chorionic membrane between the first arm and the second arm of the device of claim 1 in an open position; and
closing the device such that a sample of the biological material and tissue support member are cut and deposited into the vessel.
16. The method of claim 15 comprising:
inserting a cassette comprising a plurality of storage vessels;
closing the device such that a sample of the biological material and tissue support member are cut and deposited into at least one of the vessels; and
advancing the cassette to align an unused vessel.
17. The method of claim 15 , wherein the cassette comprises a plurality of storage vessels and a corresponding plurality of cutting elements; and opening the device results in advancement of a storage vessel.
18. A kit for collecting and storing a sample of an amniotic membrane or chorionic membrane comprising the device of claim 1 .
