Abstract

A percutaneous cellulite removal needle of the present invention can be used to make the appearance of cellulite less obvious by cutting the fibrous bridges that connect the skin to muscle/fascia or fibrous septae in the subcutaneous fat in a minimally invasive manner. The percutaneous cellulite removal needle of the present invention preferably includes a body having an internal chamber that ends at a laterally disposed aperture. A cutting mechanism is substantially positioned within the internal chamber in a retracted position and at least partially protrudes through the laterally disposed aperture in a cutting position. A situating mechanism transitions the cutting mechanism between the retracted position and the cutting position. The present invention also includes a method in which the percutaneous cellulite removal needle is inserted through the skin with the cutting mechanism in the retracted position. The cutting mechanism is then extruded so that the cutting mechanism is in the cutting position. Next the cutting mechanism is actuated, for example by rotating, to cut at least one the fibrous bridge or septae. These steps may be repeated to cut other fibrous bridges or septae reachable by the cutting mechanism. The cutting mechanism is then retracted and the percutaneous cellulite removal needle is removed.

(k) an injector.

5. The needle of claim 1, wherein each said at least one situating mechanism is selected from a group consisting of:

(a) an extrusion mechanism;

(b) a button;

(c) a lever;

(d) a handle;

(e) a dial; and

(f) a ratchet.

6. The needle of claim 1 further comprising at least one actuating mechanism for actuating a respective at least one cutting mechanism.

7. The needle of claim 1, wherein at least one of said at least one cutting mechanisms being a flexible cutting mechanism.

8. The needle of claim 1, further comprising a guide surface for guiding said at least one cutting mechanism from its retracted position to its cutting position.

9. The needle of claim 1, wherein said at least one sharp side-edge extending along the length of the portion of said cutting mechanism protruding into said subcutaneous region.

10. A percutaneous cellulite removal needle for cutting fibrous bridges that connect skin to muscle/fascia in a minimally invasive manner, said percutaneous cellulite removal needle comprising:

(a) a body comprising;

(i) a proximal end;

(ii) an outer peripheral surface;

(iii) a first internal chamber defined within said outer peripheral surface; and

(iv) a distal end substantially opposite said proximal end;

(b) a first laterally disposed aperture defined in said outer peripheral surface between said proximal end and said distal end, said first internal chamber ending at said first laterally disposed aperture;

(c) a cutting mechanism having at least one sharp side-edge, said cutting mechanism substantially positioned within said first internal chamber in a retracted position and at least partially protrudes through said laterally disposed aperture in a cutting position, said at least one sharp side-edge along at least one-third of the length of the portion of said cutting mechanism protruding from said first internal chamber when said cutting mechanism is in said cutting position; and

(d) means for situating said cutting mechanism between said retracted position and said cutting position.

11. The percutaneous cellulite removal needle of claim 10, wherein said means for situating is selected from a group consisting of:
