Abstract

Systems, instruments or devices, and methods or procedures are described in which a scalpet array is applied to a target site with the use of a pattern. The scalpet array comprises scalpets positioned on a device. Skin pixels are incised at the target site via application of a load through the scalpet array. A recipient site is prepared by positioning the pattern at the recipient site and applying the scalpet array to generate skin defects. The incised skin pixels are applied at the skin defects of the recipient site.

First claim

What is claimed is:

1. A method comprising:
configuring a device to include a scalpet array, wherein the scalpet array is removably coupled to the device and comprises a plurality of scalpets fixed on a substrate; and
configuring the scalpet array for fractional resection including aesthetic contouring of an area including a resection site by configuring each scalpet to include a cylindrical shaft including a distal end formed into a circular scalpel including a cutting surface, wherein the fractional resection includes circumferential incision and removal of skin pixels at the resection site.

2. The method of claim 1 , comprising configuring a distal region of each scalpet proximate to the distal end to incise and receive tissue.

3. The method of claim 1 , comprising configuring the distal region of each scalpet of the scalpet array to include a beveled surface.

4. The method of claim 1 , comprising configuring the distal end of each scalpet of the scalpet array to include at least one of a sharpened point and a serrated edge.

5. The method of claim 1 , comprising configuring the distal end of each scalpet of the scalpet array to include at least one pointed surface.

6. The method of claim 1 , wherein configuring the scalpet array for fractional resection comprises configuring the scalpet array to generate the incised skin pixels using at least one of piercing force, impact force, and rotational force.

7. The method of claim 1 , comprising configuring each scalpet of the scalpet array to include a through orifice.

8. The method of claim 1 , comprising configuring each scalpet of the scalpet array to include a diametric dimension approximately in a range 0.5 millimeters to 4.0 millimeters.

9. The method of claim 1 , wherein the configuring of the scalpet array comprises configuring a position of the plurality of scalpets to correspond to a harvest pattern.

10. The method of claim 9 , comprising configuring a guide plate to be positioned at the resection site, and configuring the guide plate to include perforations arranged in a configuration corresponding to the harvest pattern.

11. The method of claim 10 , comprising configuring the scalpet array for application to the resection site directly through at least one set of the perforations.

12. The method of claim 10 , comprising configuring the guide plate for use in marking the harvest pattern on a skin surface at the resection site.

13. The method of claim 12 , wherein the harvest pattern comprises an indicator on a skin surface at the resection site.

14. The method of claim 10 , comprising configuring the guide plate to be positioned directly on a skin surface at the resection site.

15. The method of claim 10 , comprising configuring the guide plate to be at least one of adherent, rigid, semi-rigid, conformable, non-conformable, and non-deformable, and to include at least one of metal, plastic, polymer, and membranous material.

16. The method of claim 1 , comprising configuring an adherent substrate to capture the incised skin pixels at the resection site.

17. The method of claim 16 , comprising configuring the adherent substrate to include at least one of a flexible substrate and a semi-porous membrane.

18. The method of claim 16 , comprising configuring the adherent substrate to maintain relative positioning of the skin pixels during the removal.

19. The method of claim 1 , comprising configuring a cutting member to transect bases of the incised skin pixels.
