Pixel array medical devices and methods
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.
1. A system comprising:
a scalpet device including a scalpet array removably coupled to a distal end of the scalpet device, wherein the scalpet array comprises a plurality of scalpets configured for fractional resection at a target site, wherein the fractional resection includes circumferential incision and removal of skin pixels, wherein each scalpet includes a cylindrical shaft including a distal end configured as a circular scalpel including a cutting surface configured to generate incised skin pixels; and
a capture system configured to capture the incised skin pixels at the target site, wherein the scalpet device is configured to couple to the capture system.
2. The system of claim 1 , comprising a guide plate including perforations arranged in a configuration corresponding to a configuration of the plurality of scalpets, and configured to be positioned at the target site.
3. The system of claim 2 , wherein the guide plate is configured to couple to a plate frame, wherein the plate frame is configured to be positioned directly on a skin surface at the target site.
4. The system of claim 2 , wherein the guide plate is configured 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.
5. The system of claim 1 , wherein the capture system includes a plate frame configured to be positioned directly on a skin surface at the target site.
6. The system of claim 5 , wherein the capture system includes a cutting member configured to couple to the plate frame.
7. The system of claim 6 , wherein the cutting member is configured to transect bases of the incised skin pixels.
8. The system of claim 5 , wherein the capture system includes an adherent substrate configured to couple to the plate frame.
9. The system of claim 8 , wherein the adherent substrate is configured to capture the incised skin pixels at the target site.
10. The system of claim 8 , wherein the adherent substrate comprises at least one of a flexible substrate and a membrane.
11. The system of claim 8 , wherein the adherent substrate is configured to maintain the incised skin pixels in a configuration of the plurality of scalpets during transfer from the target site.
12. The system of claim 1 , wherein each scalpet of the plurality of scalpets includes at least one of a beveled surface, a sharpened point, a serrated edge, and a needle.
13. The system of claim 1 , wherein each scalpet of the plurality of scalpets comprises a distal region proximate to the distal end configured to incise and receive tissue.
14. The system of claim 1 , wherein each scalpet of the plurality of scalpets comprises a through orifice.
15. The system of claim 1 , wherein at least one diametric dimension of each scalpet of the scalpet array is approximately in a range 0.5 millimeters to 4.0 millimeters.
