Claim Text:
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.
