Devices for treating skin using treatment materials located along a tip
According to some embodiments, a microdermabrasion device for treating skin comprises a handpiece assembly having a distal end and a proximal end. The handpiece assembly includes at least one delivery conduit and at least one waste conduit. The microdermabrasion device additionally comprises a tip configured to be positioned along the distal end of the handpiece assembly, wherein the tip is adapted to contact skin surface. In several embodiments, the tip comprises a lip, a first opening in fluid communication with the fluid delivery conduit and a second opening in fluid communication with the waste conduit. In one embodiment, the device includes one or more abrasive elements positioned along a distal end of the tip, wherein the abrasive elements are configured to selectively remove skin as the tip is moved relative to a skin surface.
1. A device for treating a skin surface, comprising:
a handpiece assembly comprising at least one delivery conduit; and
a tip configured to be positioned along a distal end of the handpiece assembly, the tip being configured to contact the skin surface, wherein at least one time-release material is positioned along at least a portion of the tip;
wherein the at least one delivery conduit is in fluid communication with at least one fluid source; and
wherein the at least one fluid source is configured to at least partially dissolve the at least one time-release material positioned along the tip.
2. The device of claim 1 , wherein the tip is removable from the handpiece assembly.
3. The device of claim 1 , wherein the tip comprises at least one abrasive structure or element, wherein the at least one abrasive structure or element is configured to abrade skin tissue when the device is moved relative to skin surface.
4. The device of claim 3 , wherein the at least one abrasive structure or element comprises a protruding member, a spiral ridge or an abrasive surface.
5. The device of claim 3 , wherein the at least one abrasive structure or element comprises an abrasive disc configured to be separated from the tip.
6. The device of claim 1 , wherein the at least one time-release material comprises a plurality of microcapsules, capsules or other enclosures configured to release their internal contents at various times following delivery to the skin surface.
7. The device of claim 1 , wherein the at least one time-release material comprises salicylic acid.
8. The device of claim 1 , wherein the at least one time-release material comprises a peptide, a growth factor, a sunblocking agent, an antioxidant, a hydration agent, a skin lightening agent or a skin tightening agent.
9. The device of claim 1 , wherein the at least one time-release material is impregnated along at least a portion of the tip.
10. The device of claim 1 , wherein the handpiece assembly comprises a recess configured to removably receive a cartridge, wherein an internal content of said cartridge is placed in fluid communication with the at least one delivery conduit when said cartridge is secured within the recess of the handpiece assembly.
11. The device of claim 10 , wherein the cartridge comprises a movable piston therein, said movable piston configured to urge an internal content of the cartridge toward an outlet of the cartridge.
12. The device of claim 1 , wherein the at least one fluid source comprises a container that is separate from the handpiece assembly, said container being in fluid communication with the at least one delivery conduit via a separate fluid conduit.
13. The device of claim 12 , wherein the separate container is part of a larger manifold system.
14. A device for treating a skin surface, comprising:
a handpiece assembly comprising at least one delivery conduit;
a tip configured to be positioned along the distal end of the handpiece assembly, the tip being configured to contact the skin surface during a skin treatment procedure, wherein the tip comprises at least one time-release material, the at least one time-release material being configured to effectively prolong an overall time period of a skin treatment;
wherein the at least one delivery conduit is in fluid communication with at least one fluid source; and
wherein the at least one fluid source comprises a diluting agent configured to at least partially dissolve the at least one time-release material located along the tip.
15. The device of claim 14 , wherein the tip is removable from the handpiece assembly.
16. The device of claim 14 , wherein the tip comprises at least one abrasive structure or element, wherein the at least one abrasive structure or element is configured to abrade skin tissue when the device is moved relative to skin surface.
17. The device of claim 16 , wherein the at least one abrasive structure or element comprises a protruding member, a spiral ridge or an abrasive surface.
18. The device of claim 14 , wherein the at least one time-release material comprises a peptide, a growth factor, a sunblocking agent, an antioxidant, a hydration agent, a skin lightening agent or a skin tightening agent.
19. The device of claim 14 , wherein the at least one time-release material is impregnated along at least a portion of the tip.
20. The device of claim 14 , wherein the at least one time-release material is located within a recess of the tip.
