Abstract

Photocosmetic device for use in medical or non-medical environments (e.g., a home, barbershop, or spa), which can be used for a variety of tissue treatments. Radiation is delivered to the tissue via optical systems designed to pattern the radiation and project the radiation to a particular depth. The device has a variety of cooling systems including phase change cooling solids and liquids to cool treated skin and the radiation sources. Contact sensors and motion sensor may be used to enhance treatment. The device may be modular to facilitate manufacture and replacement of parts.

Claims

1. A photocosmetic device, comprising:

a treatment head for applying radiation to a subject'"'"'s skin,

at least one radiation transmission system disposed in said head, said system configured for applying radiation to a skin portion,

wherein said transmission systems capable of pivoting about one rotational direction.

2. The photocosmetic device of claim 1, wherein device comprises at least two radiation transmission systems disposed in said head at an angle relative to one another.

3. The photocosmetic device of claim 2, wherein said transmission systems are capable of pivoting about different rotational directions.

4. The photocosmetic device of claim 3, wherein said angle between the transmission systems and said pivoting of said pivoting of the transmission systems are adapted to facilitate application of radiation to a curved area of skin.

5. The photocosmetic device of claim 1, wherein said at least two transmission systems are disposed relative to one another at an angle in a range of about 5 to about 30 degrees.

6. The photocosmetic device of claim 1, further comprising a radiation source disposed in said treatment head.

7. A photocosmetic device for use on an area of a patient'"'"'s skin comprising:

a treatment head for use in close proximity to the patient'"'"'s skin;

at least one electromagnetic radiation source located within the treatment head configured to project radiation through the treatment head onto the area of skin; and

a first mechanism coupled to the treatment head and configured to project a first substance onto the patient'"'"'s skin.

8. The device of claim 7, further comprising, an optical system to transmit radiation to the area of skin, the optical system having a surface configured to contact the patient'"'"'s skin.

9. A photocosmetic device for use on an area of a patient'"'"'s skin comprising:

a treatment head for use in close proximity to the patient'"'"'s skin;

at least one electromagnetic radiation source located within the treatment head configured to project radiation through the treatment head onto the area of skin; and

a first mechanism coupled to the treatment head and configured to project a first substance onto the patient'"'"'s skin, wherein the first substance is selected from the group consisting of a liquid, a lotion, a gas, and a plurality of components.

10. A photocosmetic device, comprising

a treatment head for applying radiation to skin,

a removable and replaceable cartridge mounted to said head, and

a radiation source for generating radiation,

wherein said radiation source is mounted to said cartridge.

11. The photocosmetic device of claim 10, further comprising an optical system mounted to said cartridge, said optical system being optically coupled to said radiation source for directing radiation to the skin.

12. The photocosmetic device of claim 11, wherein said cartridge comprises a heat sink in thermal contact with said radiation source.

13. The photocosmetic device of claim 12, wherein said cartridge comprises at least one coupling plate for fastening said radiation source and said optical system to the cartridge.

14. The photocosmetic device of claim 13, wherein said coupling plates are configured to align said radiation source with said optical system.

15. The photocosmetic device of claim 14, wherein said coupling plates are in thermal contact with said optical system.

16. The photocosmetic device of claim 14, wherein said coupling plates are formed of a thermally conductive material.

17. The photocosmetic device of claim 15, wherein said coupling plates are formed of copper.

18. The photocosmetic device of claim 14, wherein said radiation source is adapted for removable and replaceable coupling to said cartridge.

19. The photocosmetic device of claim 10, wherein said radiation source comprises one or more diode laser bars.
