Abstract

Methods, systems, and devices to treat a region of skin; the treatment may be used to stimulate the production of collagen. The region of skin undergoes a series of negative and positive pressures, where the series is characterized by an electronically regulated duty cycle. The region of skin may also be cooled to affect the modulus of elasticity of collagen inside the skin.

a strap coupled to at least one body.

11. The device of claim 10 wherein the body includes a heat source coupled to the inner surface.

12. The device of claim 10 wherein the strap includes at least one fluid conduit.

13. The device of claim 10 wherein the strap includes at least one electrical conduit.

14. A medical device to reduce the appearance of laugh lines on the human face, comprising:

at least one body with an outer surface and an inner surface defining a cavity, and a sealing surface surrounding the cavity and between the outer and inner surfaces, wherein the body is profiled to fit against a portion of a skin adjacent to a mouth, and wherein when the sealing surface is fitted against the portion of skin positive and negative pressure may be applied onto the portion of skin; and

a strap coupled to at least one body.

15. The device of claim 14 wherein the body includes a heat source coupled to the inner surface.

16. The device of claim 14 wherein the strap includes at least one fluid conduit.

17. The device of claim 14 wherein the strap includes at least one electrical conduit.

18. A medical device to reduce the appearance of stretch marks on a human mid-section, comprising:

a elongated body with an outer surface and an inner surface defining a cavity, and a sealing surface surrounding the cavity and between the outer and inner surfaces, wherein the body is profiled to fit against the mid-section and wherein when the sealing surface is fitted against the mid-section a positive and negative pressure may be applied in the cavity onto the mid-section; and

a strap coupled to the elongated body.

19. The device of claim 18 wherein the body includes a heat source coupled to the inner surface.

20. The device of claim 18 wherein the strap includes at least one fluid conduit.
