Abstract

According to some embodiments, a skin treatment assembly comprises a tip comprising a proximal end and a distal end, a container configured to secure to the tip along the proximal end of the tip, wherein the container is configured to contain a liquid, and a porous member configured to extend at least partially within an interior of the container such that it contact a liquid contained within the container, wherein the porous member is configured to extend at least partially within an interior of the tip and is configured to facilitate the transfer of liquid from the container to the distal end of the tip.

Claims

1. A skin treatment assembly, comprising:

a tip comprising a proximal end and a distal end;

a container configured to secure to the tip along the proximal end of the tip, wherein the container is configured to contain a liquid;

a porous member configured to extend at least partially within an interior of the container such that it contact a liquid contained within the container, wherein the container comprises an outer wall, and wherein a spacing exists between an outside of the porous member and an inside of the outer wall of the container; and

at least one suction passageway that extends to or near the tip, wherein the at least one suction passageway is configured to be placed in fluid communication with a suction source to selectively create suction along the distal end of the tip;

wherein the porous member is configured to extend at least partially within an interior of the tip and is configured to facilitate the transfer of liquid from the container to the distal end of the tip; and

wherein the tip comprises at least one abrasive member or structure configured to at least partially abrade skin when the assembly is moved relative to skin tissue during a treatment procedure.

2. The assembly of claim 1, wherein the porous member comprises a wicking material.

3. The assembly of claim 1, wherein the porous member is removable and replaceable relative to the tip and the container.

4. The assembly of claim 1, wherein the porous member is rigid or semi-rigid.

5. The assembly of claim 1, wherein the porous member comprises at least one internal reservoir or region.

6. The assembly of claim 5, wherein the internal reservoir or region is configured to be at least partially hollow.

7. The assembly of claim 5, wherein the internal reservoir or region is configured to contain at least one flexible or other member.

8. The assembly of claim 7, wherein the at least one flexible or other member comprises a felt or another absorbent material or member.

9. The assembly of claim 5, wherein at least one treatment material is positioned within the internal reservoir or region, wherein the at least one treatment material is configured to at least partially dissolve or release in the presence of a liquid.

10. The assembly of claim 1, wherein at least one treatment material is positioned within the porous member, wherein the at least one treatment material is configured to at least partially dissolve or release in the presence of a liquid.

11. The assembly of claim 1, wherein at least one treatment material is positioned along or near the tip, wherein the at least one treatment material is configured to at least partially dissolve or release in the presence of a liquid.

12. The assembly of claim 1, wherein the at least one abrasive member or structure comprises at least one abrading member protruding distally toward the distal end of the tip.

13. A skin treatment assembly, comprising:

a tip comprising a proximal end and a distal end;

a container configured to secure to the tip along the proximal end of the tip, wherein the container is configured to contain a liquid;

a porous member configured to extend at least partially within an interior of the container such that it contact a liquid contained within the container, wherein the container comprises an outer wall, and wherein a space exists between an outside of the porous member and an inside of the outer wall of the container; and

wherein the porous member is configured to extend at least partially within an interior of the tip and is configured to facilitate the transfer of liquid from the container to the distal end of the tip.

14. The assembly of claim 13, wherein the porous member comprises a wicking material.

15. The assembly of claim 13, wherein the porous member comprises at least one internal reservoir or region.

16. The assembly of claim 15, wherein the internal reservoir or region is configured to be at least partially hollow.

17. The assembly of claim 15, wherein the internal reservoir or region is configured to contain at least one flexible or other member.

18. The assembly of claim 15, wherein at least one treatment material is positioned within the internal reservoir or region, wherein the at least one treatment material is configured to at least partially dissolve or release in the presence of a liquid.

19. The assembly of claim 13, wherein at least one treatment material is positioned within the porous member, wherein the at least one treatment material is configured to at least partially dissolve or release in the presence of a liquid.

20. The assembly of claim 13, wherein at least one treatment material is positioned along or near the tip, wherein the at least one treatment material is configured to at least partially dissolve or release in the presence of a liquid.
