An apparatus for treating skin has a console with a user input device and a handpiece assembly. The handpiece assembly is configured to treat skin. A fluid line provides fluid communication between the console and the handpiece assembly. A manifold system is coupled to the console and controlled by the user input device. The manifold system is configured to hold releasably a plurality of fluid sources and deliver fluid from at least one of the plurality of fluid sources to the handpiece assembly.

According to some embodiments, a skin treatment assembly comprises a handpiece comprising a distal end, the handpiece comprising a recess or cavity configured to receive a cartridge or other fluid container, a tip configured to be positioned along the distal end of the handpiece, the tip being configured to contact a skin surface of a subject during use, and at least one rollerball configured to extend to or near the tip, wherein the rollerball is configured to be in fluid communication with an interior of a cartridge or other fluid container secured to the handpiece, wherein the at least one rollerball is configured to contact the skin surface of the subject during use and to facilitate the delivery of fluids to said skin surface as the rollerball is moved relative to said skin surface.

A device combines skin tissue cooling and microdermabrasion and includes: a source of ice crystals; a mechanism for propelling the ice crystals at a plurality of velocities; a controller, the controller being programmable to increase or decrease the velocity of the propelled ice crystals; the controller controls the velocity of the ice crystals to range from low speed to impinge upon and cool the skin tissue to a higher velocity to cause microdermabrasion of the skin tissue.

Devices and methods for dermatology and more particularly to fluid enhanced skin treatment system for skin rejuvenation that can use an abrasive probe for removing epidermal layers while contemporaneously providing for the infusion of therapeutic fluids into the skin.

A pumping system assembly is configured to adjust a flow rate of a liquid in a hydro dermabrasion system. The pumping system assembly includes a peristaltic pump. A tube is joined to a first opening on the peristaltic pump with a first line connector and joined to a second opening on the peristaltic pump with the second line connector. A hydro dermabrasion handpiece is configured to administer the liquid and connected to the first line connector with a first line. A liquid reservoir is configured to store the liquid for the hydro dermabrasion system and connected to the second line connector with a second line. Optionally a microcontroller is connected to the peristaltic pump and programmed with instructions to engage the rotor in a clockwise manner drawing liquid from the liquid reservoir and transferring the liquid to the hydro dermabrasion handpiece. Optionally a microcontroller is connected to the peristaltic pump and programmed with instructions to engage the rotor in a counter-clockwise manner drawing liquid from the fluid delivery system and transferring the liquid to the liquid reservoir.

The present invention is a dermal-exfoliation system that uses positive pressure to deliver salt and/or bio-inert crystalline particle abrasives or saline solution to the stratum corneum, combined with a minimal amount of negative pressure to close the loop when in contact with the skin to evacuate spent particles and dislodged skin cells and debris. An applicator handpiece is optimized for the use of the combined pressure system discussed herein for the removal of epidermal layers.

According to some embodiments, a skin treatment assembly comprises a handpiece comprising a distal end, the handpiece comprising a recess or cavity configured to receive a cartridge or other fluid container, a tip configured to be positioned along the distal end of the handpiece, the tip being configured to contact a skin surface of a subject during use, and at least one rollerball configured to extend to or near the tip, wherein the rollerball is configured to be in fluid communication with an interior of a cartridge or other fluid container secured to the handpiece, wherein the at least one rollerball is configured to contact the skin surface of the subject during use and to facilitate the delivery of fluids to said skin surface as the rollerball is moved relative to said skin surface.

The invention provides a microdermabrasion device (1) comprising a vacuum system (100) and a device tip (200), wherein the vacuum system (100) is in fluid communication with a channel inlet (120) at an inlet zone (1200) of the device tip (200), wherein the vacuum system (100) is configured to apply a vacuum to the inlet zone (1200), wherein the inlet zone (1200) further comprises an sensor (400) configured to measure a skin parameter of a part of a skin in the inlet zone (1200) and to provide a corresponding sensor signal, wherein the device tip (200) further comprises a microdermabrasion zone (1240) configured to abrade a part of said skin, and wherein the microdermabrasion device (1) further comprises a control unit (500) configured to control the vacuum as function of sensor signal information derived from the sensor signal and a predetermined relation between the sensor signal information and a vacuum setting.

An abrasive tip is used to exfoliate skin and tissue through abrasive materials integrated in the tip. The tip also delivers fluid to the skin and vacuums the fluid and abraded tissue during treatment. Treated skin will look younger and healthier in appearance. In an implementation, the tip is replaceable and disposable.

A distance between a surface of a treatment head and tip opening of a skin treatment hand piece is adjustable. In an implementation, the distance is adjusted by moving the tip opening relative to the treatment head surface. Different distances may be used to treat different skin types, problems, and conditions. In an implementation, the hand piece includes a fluid delivery and a vacuum or suction mechanism to provide various therapeutic benefits to the skin.
