Methods for preparing a skin graft without culturing or use of biologics

1. A method of skin grafting, the method comprising:

placing a skin harvester device on a donor site, the skin harvester device comprising a cutter plate having a plurality of openings disposed thereon and an actuation block for controlling movements of the cutter plate;

pulling a portion of skin at the donor site through the openings of the cutter plate;

generating a plurality of microblisters from the portion of skin pulled through the openings;

placing a first substrate in the skin harvester device and capturing the plurality of microblisters on the first substrate;

actuating the actuation block to harvest a skin graft from the portion of skin at the donor site; and

preparing said graft for transfer to a recipient site without culturing said graft or applying biologics to said graft.

2. The method of claim 1 , further comprising stretching the first substrate to increase a distance between individual microblisters of the plurality of microblisters.

3. The method of claim 2 , further comprising transferring the plurality of microblisters from the first substrate to a second substrate.

4. The method of claim 2 , further comprising stretching the first substrate mechanically.

5. The method of claim 1 , further comprising transferring the graft to the recipient site.

6. A method of skin grafting, the method comprising:

placing a skin harvester device on a donor site, the skin harvester device comprising a cutter plate having a plurality of openings disposed thereon and an actuation block for controlling movements of the cutter plate;

pulling a portion of skin at the donor site through the openings of the cutter plate;

actuating the actuation block to harvest a skin graft from the portion of skin at the donor site; and

capturing the skin graft on a first substrate placed in the harvester device.

7. The method of claim 6 , further comprising preparing the skin graft for transfer to a recipient site without culturing the skin graft or applying biologics to the skin graft.

8. The method of claim 7 , wherein the skin graft comprises a plurality of microblisters.

9. The method of claim 8 , further comprising stretching the first substrate to increase a distance between individual microblisters of the plurality of microblisters.

10. The method of claim 9 , further comprising stretching the first substrate mechanically.

11. The method of claim 9 , further comprising stretching the first substrate manually.

12. The method of claim 6 , further comprising transferring the skin graft from the first substrate to a second substrate.

13. The method of claim 6 , further comprising capturing the skin graft on the first substrate such that basal cells of the patient's skin make direct contact with the first substrate, transferring the skin graft from the first substrate to a second substrate such that the basal cells do not directly contact the second substrate, and applying the second substrate to a recipient site.

14. The method of claim 6 , further comprising transferring the skin graft to a recipient site.

15. The of claim 6 , wherein pulling the portion of the skin at the donor site through the openings of the cutter plate comprises generating a plurality of microblisters on the portion of skin at the donor site, and actuating the actuation block to harvest a skin graft from the portion of skin at the donor site comprises harvesting the skin graft from the plurality of microblisters.

16. The method of claim 15 , wherein generating the plurality of microblisters comprises applying a negative pressure, within the skin harvester device, to the patient's skin, the negative pressure pulling the patient's skin and generating the microblisters.

17. The method of claim 15 , further including generating the plurality of microblisters by heating the patient's skin, within the skin harvester device.

18. The method of claim 6 , wherein the skin graft comprises a plurality of micrografts.
