Abstract
A microdermabrasion handpiece includes a supply lumen and a return lumen in fluid communication with an abrasion chamber. A window formed at a distal end of the handpiece is off-centered from the supply lumen. The supply lumen directs a flow of abrasive particulate in a first direction. A supply nozzle adjacent to the distal end of the handpiece directs the flow of abrasive particulate at the window in a second direction different from the first direction. Methods for performing microdermabrasion are also provided.
Claims18
A handpiece adapted for use with a microdermabrasion apparatus providing a flow of abrasive particulate to the handpiece, comprising:
- a handle to be held by a user, the handle extending longitudinally between a proximal end and a distal end, the handle having a supply lumen for directing the flow of abrasive particulate in a first direction;
- a cap defining with the distal end of the handle an abrasion chamber;
- an outlet nozzle disposed at the distal end of the handle in communication with the microdermabrasion apparatus and the abrasion chamber of the cap, for directing the flow of abrasive particulate in a second direction different from the first direction and for introducing the flow of abrasive particulate into the abrasion chamber along a supply path having a direction with a distal component;
- a return orifice defined at the distal end of the handle in communication with the abrasion chamber for receiving the flow of used abrasive particulate from the abrasion chamber along a return path having a proximal component;
- and
- the cap having portions defining a window in communication with the abrasion chamber and regions exterior of the handpiece, the window extending along portions of both the supply path and the return path.
A handpiece adapted for use with a microdermabrasion apparatus providing a flow of abrasive particulate to the handpiece, comprising:
- a handle to be held by a user, the handle extending longitudinally between a proximal end and a distal end, the handle comprising a supply lumen for directing the flow of abrasive particulate in a first direction;
- a cap defining with the distal end of the handle an abrasion chamber, the cap defining a window in communication with the abrasion chamber;
- means for directing the flow of abrasive particulate in a second direction at the window, the second direction being different from the first direction;
- and
- a return orifice defined at the distal end of the handle in communication with the abrasion chamber for receiving the flow of used abrasive particulate from the abrasion chamber.
A method for performing microdermabrasion on a patient's skin, comprising the steps of:
- providing a microdemabrasion apparatus with a supply lumen, a return lumen, and a window
- introducing a flow of crystals in a first direction through the supply lumen;
- directing the flow of crystals from the supply lumen at the window in a second direction different from the first direction;
- abrading the patient's skin with the crystals;
- and
- drawing the crystals in a proximal direction through the return lumen.
