Abstract

According to some embodiments, a method of treating a skin surface of a subject comprises heating a skin surface, abrading native skin tissue of a subject using a microdermabrasion device, wherein using the microdermabrasion device comprises moving the microdermabrasion device relative to the skin surface while simultaneously delivering at least one treatment fluid to the skin surface being treated and cooling the abraded skin surface.

Claims (36)

1. A method of treating an outer layer or an epidermis of a skin surface of a body, the method comprising:

providing a fluid from a fluid source to a tip of a handpiece assembly through a fluid delivery conduit, wherein the handpiece assembly comprises a main body portion and the tip positioned along a distal end of the main body portion the tip comprising a peripheral lip configured to contact the skin surface and create a seal with the skin surface during use;

wherein the tip comprises at least one skin abrading member configured to abrade skin tissue on an outside surface of a body when the handpiece assembly is moved relative to skin tissue;

positioning the tip of the handpiece assembly in contact with an outer surface of the skin tissue; and

removing a spent fluid away from the tip through a suction conduit, wherein the suction conduit is configured to be placed in fluid communication with a suction source;

wherein fluid is configured to be provided through the fluid delivery conduit to the tip using a pulsed pattern to assist with penetration of fluid into the skin surface.

2. The method of claim 1 , wherein fluid is provided through the fluid delivery conduit using pulsing of positive pressure.

3. The method of claim 1 , wherein fluid is provided through the fluid delivery conduit using pulsing of negative pressure.

4. The method of claim 1 , wherein fluid is provided through the fluid delivery conduit using pulsing of both positive pressure and negative pressure.

5. The method of claim 1 , wherein the fluid being delivered from the fluid source through the fluid delivery conduit comprises a treatment serum or other treatment material.

6. The method of claim 1 , wherein the fluid delivery conduit is in fluid communication with a fluid manifold system, wherein the fluid manifold system is configured to receive multiple fluid containers.

7. The method of claim 1 , wherein the pulsed pattern comprises a step-like or a square wave pattern.

8. The method of claim 1 , wherein the pulsed pattern comprises a sinusoidal pattern.

9. The method of claim 1 , wherein the at least one skin abrading member of the tip comprises a sharp edge or surface.

10. The method of claim 1 , wherein the at least one skin abrading member of the tip comprises a spiral shape.

11. The method of claim 1 , further comprising controlling a frequency of pulsing of the pulsed pattern during use.

12. A method of treating an outer layer or an epidermis of a skin surface, the method comprising:

providing a fluid from a fluid source to a working end of a handpiece assembly through a fluid delivery conduit, wherein the working end of the handpiece assembly is configured to contact the skin surface and create a seal with the skin surface during a skin treatment procedure;

wherein the working end comprises at least one skin abrading member configured to abrade skin tissue when the handpiece assembly is moved relative to skin tissue; and

removing a spent fluid away from the working end through a suction conduit, wherein the suction conduit is configured to be placed in fluid communication with a suction source;

wherein fluid is configured to be provided through the fluid delivery conduit to the working end using a pulsed pattern while the working end of the handpiece assembly contacts the skin surface, wherein delivery of fluid to the working end using the pulsed pattern assists with penetration of fluid into the skin surface.

13. The method of claim 12 , wherein fluid is provided through the fluid delivery conduit using pulsing of positive pressure.

14. The method of claim 12 , wherein fluid is provided through the fluid delivery conduit using pulsing of negative pressure.

15. The method of claim 12 , wherein fluid is provided through the fluid delivery conduit using pulsing of both positive pressure and negative pressure.

16. The method of claim 12 , wherein the pulsed pattern comprises a step-like or a square wave pattern.

17. The method of claim 12 , further comprising controlling a frequency of pulsing of the pulsed pattern during use.

18. A method of treating an outer layer or an epidermis of a skin surface, the method comprising:

providing a fluid from a fluid source to a working end of a handpiece assembly through a fluid delivery conduit, wherein the working end of the handpiece assembly is configured to contact skin tissue during a skin treatment procedure;

wherein the working end comprises at least one skin abrading member configured to abrade skin tissue when the handpiece assembly is moved relative to skin tissue;

positioning the working end of the handpiece assembly in contact with an epidermal skin tissue; and

removing a spent fluid away from the working end through a suction conduit, wherein the suction conduit is configured to be placed in fluid communication with a suction source;

wherein fluid is configured to be provided through the fluid delivery conduit to the working end using positive pressure while the working end of the handpiece assembly contacts skin tissue, wherein fluid is delivered to skin tissue using a pulsed pattern to assist with penetration of fluid into skin tissue.

19. The method of claim 18 , wherein the pulsed pattern comprises a step-like or a square wave pattern.

20. The method of claim 18 , wherein fluid is configured to be delivered from the fluid source through the fluid delivery conduit using pulsing of both positive pressure and negative pressure.

21. The method of claim 18 , wherein the fluid delivery conduit is in fluid communication with a fluid manifold system, wherein the fluid manifold system is configured to receive multiple fluid containers.

22. The method of claim 18 , further comprising controlling a frequency of pulsing of the pulsed pattern during use.
