Appl. No.:

10/315478

Inventors:

Roger G. Ignon - Redondo Beach CA, US
Alejandro Herrera - Corona CA, US
William Cohen - Long Beach CA, US

Assignee:

Edge Systems Corporation - Signal Hill CA

International Classification:

A61M035/00
A61B017/50

US Classification:

604289, 290606, 290131

Abstract:

A growth factor delivery system for use in connection with microdermabrasion includes a source of growth factors. The growth material may be dry and thus mixed in with the abrasion media. The dry growth material would therefore be applied to the target skin area simultaneously with the abrasion media by a single handpiece. The growth material may comprise a fluid to be delivered by a separate handpiece. The fluid source may be within the handpiece or external thereto. The fluid source may be contained in a removable cartridge adapted to fit within the handpiece. Thus, a method and system is provided for using disposable cartridges of growth fluids.

Abstract:

A human growth factor delivery system for use in connection with dermabrasion includes a source of human growth factors in fluid. The growth factor fluid may be applied to the target skin area simultaneously with the step of abrading the skin by a single handpiece. Furthermore, the fluid is caused to penetrate by a combination of the abrasive elements, a vacuum, and a positive pressure applied in bursts, which produces a massaging effect. The fluid source may be contained in a removable cartridge adapted to fit within the handpiece. The fluid is drawn from the cartridge by the vacuum. The vacuum also draws a portion of target skin into a space of the handpiece for contact with an abrasion element. The vacuum furthermore draws excess fluid and removed skin cells into a disposable or reusable canister.
