1. A minimally invasive skin treatment device, comprising:
- a handpiece 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 conduit extending through a side of the perimeter elevation to the recessed area;
a needle configured to at least partially extend through the conduit and into the recessed area;
a guidance track operably connected to the handpiece, wherein the guidance track is configured to constrain a portion of the needle in contact with the guidance track to move along a predetermined path to cooperatively move a distal end of the needle within the recessed area in a plane substantially parallel to the top of the handpiece and within a region of a predetermined shape defined by the predefined path;
a pump;
a source of injectable fluids in fluid communication with said pump; and
wherein the needle is in fluid communication with the pump, the needle being configured to inject the injectable fluids into a tissue disposed in the recessed area;
a microprocessor having graphical user interface, wherein the pump is configured to communicate information specifying a volume of a fluid injected into the tissue to the microprocessor;
wherein the microprocessor is configured to use the graphical user interface to prompt a user to enter information specifying at least one of a concentration of a component of the fluid and a weight of a patient;
wherein the microprocessor includes logic for determining a maximum dosage the fluid injected based on the weight of the patient, the concentration of the component of the fluid, and the volume of the fluid injected;
wherein the microprocessor is configured to cause the graphical interface to display at least one warning message when the volume of the fluid injected exceeds a predefined threshold which is less than the maximum dosage; and
wherein the microprocessor is configured to instruct the pump to terminate an injection when the volume of the fluid injected reaches the maximum dosage.

Abstract
A dermatological skin treatment device is provided. The device comprises a handpiece and a cutting tool, wherein the tool is inserted through the conduit and percutaneously inserted into a tissue disposed within a recessed area of the handpiece. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes.
