Abstract
A treatment for subcutaneous fat and/or cellulite includes delivering a beam of radiation to a subcutaneous fat region disposed relative to a dermal interface in a target region of skin. The beam of radiation affects at least one fat cell in the subcutaneous fat region without causing substantial unwanted injury to the epidermal region and causes thermal injury to a dermal region to induce collagen formation to strengthen the target region of skin in a target region of skin. The treatment can include cooling an epidermal region of the target region of skin.
Claims12
An apparatus for treating cellulite in a target region of skin, comprising:
- a source generating a beam of radiation, the source including a fiber coupled laser diode array including a plurality of discrete emitter sections mounted on a substrate;
- a delivery system coupled to the source for generating a beam of radiation and including at least a handpiece to direct the beam of radiation to a target region of skin and a spacer to space the delivery system from skin surface,
- wherein the handpiece also includes a high frequency ultrasound device constructed and arranged to be placed in contact with the skin surface to measure position of a dermal-subcutaneous interface, so that the beam of radiation is directed to the dermal-subcutaneous interface, and
- a focusing system to focus the beam of radiation below the surface of the skin in the target region of skin and wherein a focusing system element is constructed and arranged to contact the skin and be pressed into or against the skin to displace blood in dermis and increase transmission of the beam of radiation through the dermis to reduce unwanted injury to the skin,
- wherein the focusing system comprises a planoconvex lens to direct and focus the beam of radiation to the target region of skin 0.5 mm to 5 mm below an exposed surface of skin.
An apparatus for treating cellulite in a target region of skin, comprising:
- a source generating a beam of radiation, the source including a fiber coupled laser diode array including a plurality of discrete emitter sections mounted on a substrate;
- a delivery system coupled to the source for generating a beam of radiation and including at least a handpiece to direct the beam of radiation to a target region of skin and a spacer to space the delivery system from skin surface,
- wherein the handpiece also includes a high frequency ultrasound device constructed and arranged to be placed in contact with the skin surface to measure position of a dermal-subcutaneous interface, so that the beam of radiation is directed to the dermal-subcutaneous interface, and
- a focusing system to focus the beam of radiation below the surface of the skin in the target region of skin and,
- a vacuum system and wherein the focusing system comprises a lens with a concave contact surface and an orifice in the lens communicating with the vacuum system.
