Filed:

Dec 10, 2002

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.

International Classification:

A61B 17/50

US Classification:

606131, 606 1

Abstract:

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.

US Classification:

604/140000

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.

Appl. No.:

17/685005

Inventors:

Ed F. Nicolas - Signal Hill CA, US
William Cohen - Los Alamitos CA, US

International Classification:

A61B 17/54

Abstract:

The present invention is an applicator tip for a hand piece assembly used in dermal abrasion procedures, the applicator tip having a cap shape with a plurality of apertures that form ports communicating with a fluid supply line in the hand piece assembly and a vacuum source to remove the abrading fluid. The fluid is introduced onto the outer abrading surface of the applicator tip through a first central aperture and spreads out along the outer abrading surface when the applicator tip is placed against the patient's skin. Recesses in the outer abrading surface establish pathways for the abrading fluid to move along as the applicator tip is moved over the patient's skin. The fluid emitting from the central port is moved into one of four quadrants defined by recesses in the outer abrading surface, each quadrant serving as a fluid chamber that receives fluid from the central fluid supply port. Each sector shaped chamber includes within its border a C-shaped barrier with its opening facing a dividing sector wall. As the applicator tip forms a seal with the patient's skin, fluid is introduced through the supply port and through the entrance of the chamber, filling each chamber with working fluid as the working fluid flows to and around the C-shaped barrier. Disposed inside each C-shaped barrier is a respective vacuum port that removes the working fluid from each chamber. Fluid from each chamber is vacuumed through its vacuum port after having flowed around a maze-like path, navigating the C-shaped barrier and sector walls in a vortex flow pattern.
