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 (32)

1. A skin treatment system configured to at least partially remove an outer layer or an epidermis of a skin surface using mechanical exfoliation, the system comprising:

a handpiece assembly including a main body portion and a 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;

a fluid delivery conduit configured to place the tip in fluid communication with a fluid source, wherein fluid is configured to be delivered to the tip through the fluid delivery conduit and a first opening in fluid communication with the fluid delivery conduit;

a suction conduit configured to place the tip in fluid communication with a suction source, wherein, simultaneously, (1) spent fluid and debris are configured to be removed away from the tip through the suction conduit and a second opening in fluid communication with the suction conduit, and (2) fluid is configured to be delivered to the tip through the fluid delivery conduits and a first opening when the suction source is activated and the peripheral lip creates a seal with the skin surface;

wherein the system is configured to deliver fluid from the fluid source to the tip using a pulsing of negative pressure created by the suction source;

a control module configured to regulate the pulsed pattern of fluid; and

a controller operatively coupled to the control module, wherein manipulation of the controller by a user regulates a level of pulsing of fluid during use;

wherein the tip comprises at least one skin abrading member configured to abrade, at least partially, the epidermis when the handpiece assembly is moved relative to skin tissue; and

wherein the first opening, the second opening and the at least one skin abrading member are positioned within an interior of the peripheral lip.

2. The system 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.

3. The system 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.

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

5. The system of claim 1 , wherein the pulsed pattern comprises a sinusoidal pattern.

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

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

8. A skin treatment system configured to at least partially remove an outer layer or an epidermis of a skin surface using mechanical exfoliation, the system comprising:

a handpiece assembly comprising a working end configured to contact the skin surface and create a seal with the skin surface during use;

a suction conduit configured to place the working end in fluid communication with a suction source, wherein the suction conduit is configured to remove spent fluid from the working end when the suction source is activated and the working end creates a seal with the skin surface;

a fluid delivery conduit configured to place the working end in fluid communication with a fluid source, wherein fluid is configured to be delivered through the fluid delivery conduit to the working end in a pulsed pattern by generating a pulsed suction along the working end, wherein the pulsed suction and a delivery of fluid to the working end is accomplished using the pulsed suction when the suction source is activated and the working end creates a seal with the skin surface, wherein delivery of fluid to the working end using the pulsed pattern assists with penetration of fluid into the skin surface; and

a button or other controller configured to regulate a level of pulsing of the fluid from the fluid source to the working end;

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

9. The system of claim 8 , 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.

10. The system of claim 8 , wherein the pulsed pattern comprises a step-like or a square wave pattern.

11. A skin treatment system configured to at least partially remove an outer layer or an epidermis of a skin surface using mechanical exfoliation, the system comprising:

a handpiece assembly comprising a working end, the working end being rigid and configured to contact the skin surface and create a seal with the skin surface during use;

a suction conduit configured to place the working end in fluid communication with a suction source, wherein the suction conduit is configured to remove spent fluid from the working end when the suction source is activated and the working end creates a seal with the skin surface;

a fluid delivery conduit configured to place the working end in fluid communication with a fluid source, wherein the system is configured to deliver fluid from the fluid source through the fluid delivery conduit in a pulsed pattern by generating a pulsed suction along the working end, wherein a delivery of fluid to the working end is performed using only the pulsed suction generated along the working end when the suction source is activated and the working end creates a seal with the skin surface; and

a button or other controller configured to be manipulated by a user and configured to regulate a level of pulsing of the fluid being delivered to the working end from the fluid source;

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

12. The system of claim 11 , wherein the pulsed pattern comprises a step-like pattern.

13. The system of claim 11 , wherein the pulsed pattern comprises a square wave pattern.

14. The system of claim 11 , 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.
