DEVICES AND METHODS FOR TREATING SKIN
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 microdermabrasion device for treating a skin surface, comprising:
a handpiece assembly having a distal end and a proximal end, said handpiece assembly comprising at least one delivery conduit and at least one waste conduit;
a tip configured to be positioned along the distal end of the handpiece assembly, said tip being configured to contact the skin surface;
a flow control device or feature included within the handpiece assembly to regulate the flow of fluids through the at least one delivery conduit;
wherein the tip comprises a lip, a first opening in fluid communication with the at least one fluid delivery conduit and a second opening in fluid communication with the at least one waste conduit;
at least one abrasive element positioned along a distal end of the tip, said abrasive element being configured to selectively remove skin as the tip is moved relative to a skin surface;
wherein the first opening, the second opening and the at least one abrasive element of the tip are positioned within an interior of an outer periphery formed by the lip;
wherein the at least one waste conduit is in fluid communication with a vacuum source to selectively remove debris away from the tip;
wherein the at least one delivery conduit is in fluid communication with the at least one waste conduit and the vacuum source when the lip contacts a skin surface; and
wherein the at least one delivery conduit is configured to selectively deliver at least one time-release material to the skin surface being treated.
