DEVICES, SYSTEMS AND METHODS FOR SKIN TREATMENT
A device for treating the skin comprises a handpiece assembly having a distal end and a proximal end, a cartridge comprising an interior cavity and a tip on the distal end of the handpiece assembly. The handpiece assembly includes a fluid delivery conduit and a waste conduit. In addition, the cartridge is coupled to the handpiece assembly with the interior cavity of the cartridge being in fluid communication with the fluid delivery conduit. Further, the tip is configured to contact the skin. The tip comprises a peripheral lip, a first opening in fluid communication with the fluid delivery conduit, a second opening in fluid communication with the waste conduit and an abrasive element. The first opening, the second opening and the abrasive element of the tip are generally positioned within the peripheral lip.
1 . A device for treating a skin surface, comprising:
a handpiece assembly having a distal end and a proximal end, the handpiece assembly comprising at least one delivery conduit and at least one waste conduit;
a recess within the handpiece assembly, said recess being configured to receive a cartridge comprising an interior cavity;
wherein the interior cavity of the cartridge is placed in fluid communication with the fluid delivery conduit when the cartridge is secured within the recess; and
a tip configured to be positioned along the distal end of the handpiece assembly, said tip being configured to contact the skin surface;
wherein the tip comprises a peripheral lip, a first opening in fluid communication with the fluid delivery conduit and a second opening in fluid communication with the waste conduit and an abrasive element;
wherein the first opening, the second opening and the abrasive element are positioned along an interior of the peripheral lip;
wherein the at least one waste conduit is configured to be in fluid communication with a vacuum to selectively remove debris away from the tip; and
wherein the at least one delivery conduit is placed in fluid communication with the at least one waste conduit and the vacuum when the peripheral lip contacts a skin surface.
