FLUID-JET DISSECTION SYSTEM AND METHOD FOR REDUCING THE APPEARANCE OF CELLULITE
First Claim
1. A system for minimally invasive skin treatment, comprising:
- a platform having a perimeter elevation and a top which cooperatively define a recessed area, an inner side of the perimeter elevation and top defining an apposition surface facing into the recessed area;
an injection port provided on the platform, the injection port positioned about an entry hole through the top of the platform; and
an injection device having a needle, the injection device being configured to be slidably disposed in the injection port such that a distal end of the needle passes through the entry hole into the recessed area and the injection device is removably secured perpendicular to the platform, andwherein the distal end of the needle has a nozzle configured to discharge a fluid in a direction orthogonal to an axis of the needle and parallel to the top of the platform.

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.

21. A method of treating cellulite, comprising:
-
positioning a platform having a recessed area over a dermis, the platform having an injection port and an entry hole through a top of the platform; applying a force to the platform to move a portion of the dermis into the recessed area to substantially fill the recessed area, such that the portion of the dermis is in contact with an inner surface of the platform and a first and second subcutaneous tissue are disposed in the recessed area; providing an injection device having a needle; inserting a distal end of the needle through the injection port and through the entry hole such that the injection device is perpendicular to the platform and the distal end of the needle is percutaneously inserted through the dermis and into the first subcutaneous tissue; and discharging at a pressure between 20 and 150 Bar a fluid through a nozzle in a side of the distal end of the needle and inside the first subcutaneous tissue, the discharge being substantially parallel to the top of the platform. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)

29. A system for minimally invasive skin treatment, comprising:
-
a recessed platform having a perimeter elevation and a top which cooperatively define a recessed area, an inner side of the perimeter elevation and the top defining an apposition surface facing into the recessed area; a vacuum fitting operably connected to one of the top of the platform and the perimeter elevation of the platform and in fluid communication with the recessed area; a vacuum pump in fluid communication with the vacuum fitting, the vacuum pump being configured to supply a suction force to the recessed area to pull a tissue snugly and securely against the apposition surface when the recessed area is placed over the tissue, multiple injection ports provided on and raised above the top of the platform, each injection port positioned about an entry hole through the top of the platform; and an injection device having a needle and a needle housing, the housing including an upper body and a base, the upper body including a handpiece and having a larger diameter than the base, the base being configured to be slidably disposed in a selected injection port such that a portion of the needle passes through a corresponding entry hole and the injection device is removably secured perpendicular to the platform in a manner such that a bottom rim of the upper body rests flush upon a top rim of the selected injection port when the injection device is fully inserted into the injection port, wherein a distal end of the needle has a nozzle flush with a side of the needle and is configured to discharge a fluid at a pressure between 20 and 150 Bar in a direction orthogonal to an axis of the needle and parallel to the top of the platform, and wherein each of the multiple injection ports is covered by an elastomeric septum, the elastomeric septum being configured to be pierced by the needle and to substantially self-seal when the needle is removed such as to substantially prevent a vacuum leakage from the recessed area when the suction force is supplied.
