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.

Claims (40)

1. A microdermabrasion apparatus, comprising:

a supply of abrasion media;

a supply of growth material;

at least one handpiece to apply the abrasion media and the growth material to a target area;

a source of oxygen in communication with the handpiece; and

a mechanism for removing the abrasion media from the target area.

2. The apparatus of claim 1 , wherein the growth material is dry.

3. The apparatus of claim 2 , wherein the growth material is mixed with the abrasion media.

4. The apparatus of claim 1 , further comprising a valve to control a flow of the oxygen to the handpiece.

5. The apparatus of claim 1 wherein the mechanism comprises a vacuum source.

6. The apparatus of claim 5 , wherein the vacuum source is disposed downstream from the handpiece, the apparatus further comprising a positive pressure source disposed upstream from the handpiece.

7. A fluid delivery apparatus for applying a fluid to a target skin area, comprising:

a handpiece comprising a housing;

a cartridge disposed substantially within the handpiece, the cartridge holding a supply of fluid and including an applicator adapted to apply the fluid to a target skin area; and

a vacuum source coupled to the handpiece and adapted to draw the fluid out of the cartridge and through the applicator; wherein a space is defined within the housing and exterior to the cartridge; and the space is in communication with the vacuum source.

8. The apparatus of claim 7 , wherein the applicator comprises a sponge.

9. The apparatus of claim 7 , wherein the applicator comprises a roller.

10. The apparatus of claim 7 , wherein the applicator comprises a membrane.

11. The apparatus of claim 7 , wherein the housing is adapted to slidingly receive the cartridge.

12. The apparatus of claim 7 , wherein the handpiece comprises a beveled distal portion adapted to contact the target skin area.

13. The apparatus of claim 7 , wherein the handpiece comprises a distal portion with a plurality of vacuum ports, the vacuum ports disposed axially about the applicator.

14. The apparatus of claim 7 , wherein the handpiece comprises a housing with a removable cap to facilitate assembly and removal of the cartridge.

15. The apparatus of claim 7 , wherein the supply fluid contains at least one growth factor.

16. The apparatus of claim 7 , wherein the housing comprises a distal portion adapted to form a seal with the target skin area.

17. The apparatus of claim 16 , wherein the space is sealed off from any area exterior to the handpiece when the housing forms the seal with the target skin area.

18. A method for microdermabrading skin, comprising the steps of:

abrading a target skin area with microdermabrasion media with a first handpiece;

applying growth material to the target skin area with a second handpiece;

retrieving the microdermabrasion media from the target skin area;

retrieving at least a portion of the growth material from the target skin area; disposing the growth material in an aqueous solution; and further disposing the aqueous solution with the growth material upstream from the second handpiece.

19. The method of claim 18 , wherein the growth material is dry, the method further comprising the step of:

mixing the dry growth material with the microdermabrasion media prior to the applying step.

20. The method of claim 18 , further comprising the step of carrying the aqueous solution with the second handpiece.

21. The method of claim 20 , wherein the step of disposing the aqueous solution with the growth material within the second handpiece comprises the step of retaining the aqueous solution with a cartridge carried by the handpiece.

22. The method of claim 21 , further comprising the step of:

disposing an applicator on a distal end of the cartridge, and

wherein the step of applying the growth material to the target skin area with the second handpiece comprises contacting the target skin with the applicator.

23. The method of claim 22 wherein the step of disposing the applicator on the distal end of the cartridge comprises disposing a sponge applicator.

24. The method of claim 22 wherein the step of disposing the applicator on the distal end of the cartridge comprises disposing a roller applicator.

25. The method of claim 22 wherein the step of disposing the applicator on the distal end of the cartridge comprises disposing a membrane applicator.
