Abstract

According to some embodiments, a skin treatment assembly comprises a handpiece comprising a distal end, the handpiece comprising a recess or cavity configured to receive a cartridge or other fluid container, a tip configured to be positioned along the distal end of the handpiece, the tip being configured to contact a skin surface of a subject during use, and at least one rollerball configured to extend to or near the tip, wherein the rollerball is configured to be in fluid communication with an interior of a cartridge or other fluid container secured to the handpiece, wherein the at least one rollerball is configured to contact the skin surface of the subject during use and to facilitate the delivery of fluids to said skin surface as the rollerball is moved relative to said skin surface.

Claims

1. A skin treatment assembly, comprising:

a handpiece comprising a distal end, the handpiece comprising a recess or cavity configured to receive a cartridge or other fluid container;

a tip configured to be positioned along the distal end of the handpiece, the tip being configured to contact a skin surface of a subject during use;

at least one rollerball configured to extend to or near the tip, wherein the at least one rollerball is configured to be in fluid communication with an interior of a cartridge or other fluid container secured to the handpiece, wherein the at least one rollerball is configured to contact the skin surface of the subject during use and to facilitate the delivery of fluids to said skin surface as the rollerball is moved relative to said skin surface;

at least one suction conduit extending to the tip, wherein the at least one suction conduit is configured to be placed in fluid communication with a vacuum source to selectively apply suction to the tip during use; and

at least one abrasive structure or member located on, near or along the tip, the at least one abrasive structure or member being configured to selectively exfoliate the subject skin during use;

wherein an area immediately proximal to the at least one rollerball is configured to increase a presence of fluids from the cartridge or other fluid container along the rollerball.

2. The assembly of claim 1, wherein the at least one rollerball is secured to a distal end of the cartridge or other fluid container.

3. The assembly of claim 1, wherein the at least one rollerball is secured to at least one of the handpiece and the tip.

4. The assembly of claim 1, wherein the at least one rollerball is in direct fluid communication with the interior of the cartridge or other fluid container.

5. The assembly of claim 1, wherein the at least one rollerball is in indirect fluid communication with the interior of the cartridge or other fluid container.

6. The assembly of claim 5, wherein the at least one rollerball is in fluid communication with the interior of the cartridge or other fluid container via one or more fluid conduits or passages.

7. The assembly of claim 1, wherein the area proximal to the at least one rollerball comprises one or more vanes that increase an effective surface area of an area immediately adjacent the at least one rollerball along or near the cartridge or other fluid container to help maintain fluids from the cartridge or other fluid container immediately adjacent the at least one rollerball.

8. The assembly of claim 1, further comprising a porous member immediately adjacent the at least one rollerball to improve fluid communication between the at least one rollerball and fluid from the cartridge or other fluid container.

9. The assembly of claim 1, wherein the tip comprises a peripheral lip, wherein the peripheral lip is sized, shaped and configured to contact a subject'"'"'s skin tissue and generally form a seal along said skin tissue.

10. The assembly of claim 9, wherein the at least one rollerball is positioned within an interior of the peripheral lip and extends to a height below the height of the peripheral lip.

11. The assembly of claim 1, wherein the at least one rollerball is resiliently biased distally.

12. A skin treatment assembly, comprising:

a handpiece comprising a distal end, the handpiece being configured to receive a cartridge or being configured to be placed in fluid communication with a fluid source;

a tip configured to be positioned along the distal end of the handpiece, the tip being configured to contact a skin surface of a subject during use;

a rollerball configured to extend to or near the tip, wherein the rollerball is configured to be in fluid communication with an interior of a cartridge or other fluid container secured to the handpiece, wherein the rollerball is configured to contact the skin surface of the subject during use and to facilitate the delivery of fluids to said skin surface as the rollerball is moved relative to said skin surface; and

at least one suction conduit extending to or near the tip, wherein the at least one suction conduit is configured to be placed in fluid communication with a suction source to selectively apply suction to the tip during use;

wherein an area immediately proximal to the rollerball is configured to increase a presence of fluids from the cartridge or other fluid container along the at least one rollerball.

13. The assembly of claim 12, further comprising at least one abrasive structure or member located on, near or along the tip, the at least one abrasive structure or member being configured to selectively exfoliate the subject skin during use.

14. The assembly of claim 12, wherein the rollerball is in direct or indirect fluid communication with the interior of the cartridge or other fluid container.

15. The assembly of claim 12, further comprising a porous member immediately adjacent and proximal to improve fluid communication between the rollerball and fluid from the cartridge or other fluid container.

16. The assembly of claim 12, wherein the tip comprises a peripheral lip, wherein the peripheral lip is sized, shaped and configured to contact a subject'"'"'s skin tissue and generally form a seal along said skin tissue.

17. The assembly of claim 12, wherein the area proximal to the rollerball comprises one or more vanes that increase an effective surface area of an area immediately adjacent the rollerball along or near the cartridge or other fluid container to help maintain fluids from the cartridge or other fluid container immediately adjacent the rollerball.

18. The assembly of claim 12, wherein the rollerball is resiliently biased distally.

19. A skin treatment assembly, comprising:

a handpiece comprising a distal end, the handpiece being configured to receive a cartridge or being configured to be placed in fluid communication with a fluid source;

wherein a distal end of the handpiece is configured to contact a skin surface of a subject during use; and

a rollerball configured to extend to or near the distal end of the handpiece, wherein the rollerball is configured to be in fluid communication with an interior of a cartridge or other fluid container secured to the handpiece, wherein the rollerball is configured to contact the skin surface of the subject during use and to facilitate the delivery of fluids to said skin surface as the rollerball is moved relative to said skin surface; and

at least one suction conduit extending to or near the distal end of the handpiece, wherein the at least one suction conduit is configured to be placed in fluid communication with a suction source to selectively apply suction to the distal end of the handpiece tip during use;

wherein an area immediately proximal to the rollerball is configured to increase a presence of fluids from the cartridge or other fluid container along the rollerball.

20. The assembly of claim 19, further comprising at least one suction conduit extending to or near the distal end of the handpiece, wherein the at least one suction conduit is configured to be placed in fluid communication with a suction source to selectively apply suction to the tip during use.
