Methods for treating the skin using vacuum

摘要

An instrument and technique for the removal of epidermal layers in a controlled manner utilizing a hand-held instrument with a working end that (i) a vacuum aspiration system, (ii) a source for delivery of a sterile fluids or pharmacological agents to the skin; and (iii) a skin interface surface in the working end that has specially shape structure for abrading surface layers of the patient's epidermis as the working end is moved over the patient's skin while at the same time causing rapid penetration of the fluids into the skin for therapeutic purposes. Movement of the working end across the skin causes abrasion of the surface layers in a path over the patient's skin.

1. A method of treating a skin surface of a subject, comprising:
positioning a handheld device against a skin surface of the subject, the handheld device comprising:
a body comprising a housing;a working end portion positioned along a first end of the body, the working end portion comprising a distal end configured to contact the skin surface, wherein the working end portion comprises a perimeter along the distal end;a first aperture arrangement comprising at least one first port located along or near the working end portion, the at least one first port being in fluid communication with a vacuum source via at least one passageway; anda second aperture arrangement comprising at least one second port located along or near the working end portion, the at least one second port being in fluid communication with a treatment media source; activating the vacuum source to simultaneously deliver a treatment media to the skin surface through the at least second port, wherein the treatment media comprises a liquid, and to aspirate spent treatment media through the at least one first port and the at least one passageway, thereby selectively providing a volume of the treatment media to the skin surface of the subject; wherein activating the vacuum source facilitates delivery of treatment media to subsurface skin tissue of the subject and causes adjacent skin surface to at least partially puff up to facilitate the treatment method.
