Abstract: According to some embodiments, a system for treating skin includes a handpiece assembly comprising a tip and a main body portion, the main body portion comprising an interior cavity and at least one canister configured to store at least one of a treatment material and a waste material. The treatment material and/or the waste material is in fluid communication with the tip.

Abstract: 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. In some embodiments, the delivery conduit is configured to selectively deliver at least one time-release material to the skin surface being treated.

Abstract: 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.

Abstract: A surgical suction system and method includes a source of suction and a conduit having a distal end and a proximal end. At its distal end, the conduit has a diameter not greater than about 5/8 inch to provide limited access to the surgical site and an inside diameter not less than about 1/4 inch to accommodate the bone fragments in the waste slurry. A coupling is provided for connecting the proximal end of the conduit to the suction source in order to provide suction at the distal end of the conduit at a velocity not less than about ninety miles per hour. A fluid containment vessel can be connected between the conduit and the source of suction to provide a liquid trap for the waste slurry passing along the conduit. An associated method includes the step of activating the suction source to provide suction at the distal end of the conduit with a velocity not less than ninety miles per hour.

Abstract: A suction delivery system for removing surgical smoke from an operative site includes a hose having the configuration of a first tube and adapted to extend generally between a suction source and the operative site. A wand coupled to the distal end of the hose has the configuration of a second tube with first portions of the wand define a major suction inlet while second portions of the wand define a lateral opening which relieves suction pressure when the major inlet is blocked by tissue. A tip section of the wand includes a vane extending at least partially across the major opening and a strut extending to support the vane outwardly of the major opening. The tip section also includes means providing a laterally visible indication of the degree of contamination of the system.

Abstract: A surgical air vacuum apparatus includes an air pump disposed in a primary air channel for moving air between an inlet port and an outlet port of the vacuum. The air pump has properties for generating heat while moving the air, and the moving air has characteristics for cooling the pump. An air filter disposed in the primary channel has a tendency to block the air that would otherwise cool the air pump. Means is provided for combining a secondary air channel and the primary air channel along at least one passage to introduce bleed air to the pump when the filter blocks the primary channel.
