Devices and systems for treating skin surfaces
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.

9. A device for treating a skin surface, comprising:
a handpiece assembly comprising a main body portion and a tip positioned along a distal end of the main body portion;
at least one delivery conduit for delivering a liquid to the tip, wherein the at least one delivery conduit is positioned, at least partially, within the main body portion of the handpiece assembly;
at least one waste conduit for removing spent liquid or other debris away from the tip, wherein the at least one waste conduit is configured to be placed in fluid communication with a vacuum source;
a recess along the main body portion of the handpiece assembly, the recess being sized and configured to receive a container, the container being configured to contain a liquid, wherein the recess extends to an exterior of the main body portion and is directly accessible from the exterior of the main body portion for insertion of a container into the recess during use, to permit positioning a container into or from the recess during a procedure; and
a flow control feature configured to enable a user to selectively regulate a flowrate of liquid through the at least one delivery conduit, wherein the flow control feature is positioned in a fluid pathway of the at least one delivery conduit;
wherein the flow control feature is configured to contact liquid that is being delivered through the at least one delivery conduit;
wherein an interior of a fluid container is in fluid communication with the at least one fluid delivery conduit when the fluid container is received within the recess; and
wherein the tip comprises at least one inlet in fluid communication with the at least one fluid delivery conduit.
10. The device of claim 9 , wherein the at least one waste conduit is positioned at least partially within an interior of the main body portion of the handpiece assembly.
