1. A device for dissection of tissue, comprising:
- a platform having a top surface, a bottom surface, and a downwardly extending wall about a perimeter of the platform,wherein the bottom surface and the downwardly extending wall about the perimeter of the platform collectively form a recessed area in which a tissue to be dissected may be positioned;
the recessed area being operatively connected to a suction mechanism,wherein the suction mechanism is configured to supply a suction force to the recessed area to allow the tissue to be dissected to be positioned against the bottom surface;
one or more ports positioned on top of the platform, each of the one or more ports positioned about a corresponding entry hole passing into the recessed area, wherein each of the one or more ports comprises a portion that is raised above the top surface of the platform that defines a corresponding well within a selected port and that limits an insertion depth of a needle or other cutting tool; and
the needle or other cutting tool comprising a base and an upper body,wherein the needle or other cutting tool is configured to be removably secured to the platform,wherein an outer perimeter of the base fits within an inner perimeter of a selected well,wherein the upper body of the needle or other cutting tool is fluidically connected to a solution supply tubing, andwherein the solution supply tubing is configured to deliver a solution to a lumen portion of the needle or other cutting tool,wherein the needle or other cutting tool is configured to allow at least a portion of the needle or other cutting tool to be inserted into a selected port such that a distal end of the needle or other cutting tool passes through the corresponding entry hole into the recessed area, through a dermis and into a subcutaneous region of the tissue to be dissected positioned in contact with the bottom surface to a depth within the subcutaneous region,wherein a lower portion of the upper body is configured to contact a portion of the corresponding well that is raised above the top surface of the platform when the distal end of the needle or other cutting tool is at the depth within the subcutaneous region, andwherein the needle or other cutting tool dissects the tissue to be dissected in a plane below a surface of the tissue to be dissected in contact with the bottom surface.

Abstract
A minimally invasive skin treatment system includes a platform having a recessed area on its bottom and one or more injection ports orthogonal to its top, each injection port including a through-hole to the recessed area. The system includes an injection device including a needle slidably disposed in a selective port such that the needle passes into the recessed area and percutaneously through a dermis disposed within the recessed area. A nozzle is configured to discharge a fluid at a high pressure in a direction orthogonal to an axis of the needle and parallel to the top of the platform to cut create a plane of dissection within the subcutaneous tissue.

5. A device for dissection of tissue, comprising:
-
a platform having a top surface, a bottom surface, and a downwardly extending wall about a perimeter of the platform, wherein the bottom surface and the downwardly extending wall about the perimeter of the platform collectively form a recessed area in which a tissue to be dissected may be positioned; the recessed area being operatively connected to a suction mechanism configured to supply a suction force to the recessed area to position the tissue to be dissected against the bottom surface; one or more ports positioned on the platform, each of the one or more ports positioned about a corresponding entry hole in communication with the recessed area, wherein each of the one or more ports comprises a well; and a needle or other cutting tool comprising a base, an upper body, and a swivel fitting positioned in the upper body, wherein the swivel fitting comprises an upper and lower section, wherein the upper and lower sections are configured to rotate independently from one another, thereby allowing rotation of the needle or other cutting tool, wherein the needle or other cutting tool is configured to be removably secured to the platform, wherein the needle or other cutting tool is configured to allow a portion of the needle or other cutting tool to be inserted into a selected port to pass a distal end of the needle or other cutting tool through the corresponding entry hole into the recessed area and into a subcutaneous region of the tissue to be dissected positioned in contact with the bottom surface to a depth a depth below a surface of the tissue to be dissected in contact with the bottom surface, and wherein each well comprises a raised portion that extends above the top surface of the platform and interacts with a rim on the upper body of the needle or other cutting tool and limits the insertion depth of the needle or other cutting tool. - View Dependent Claims (6, 7, 8, 9, 10, 11)
