Patent number: 9539439Abstract: 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.Type: GrantFiled: April 1, 2015Date of Patent: January 10, 2017Assignee: Candela CorporationInventors: Christopher J.

Patent number: 7935139Abstract: A method and apparatus are disclosed for improving bodily safety during exposure to an intense pulsed light source by diverging the light, such as with a diffuser. At a first position of the distal end of the light source the energy density of exit light from the distal end is substantially equal to the energy density of the light required for desired applications, such as effecting an aesthetic improvement without appearance of purpura or scarring, and at a second position of the distal end the radiance of the light emitted therefrom is significantly less than the radiance of the intense pulsed light. Eye safety is further enhanced by attaching at least one element of adjustable opacity to the handpiece of the light source, so that subcutaneously backscattered light may be absorbed by the at least one element.Type: GrantFiled: December 6, 2004Date of Patent: May 3, 2011Assignee: Candela CorporationInventor: Michael Slatkine

Patent number: 7771374Abstract: A method and apparatus are disclosed for enhancing the absorption of light in targeted skin structures and for the inhibition of pain transmission during light based treatments of the skin. After applying a vacuum to a vacuum chamber placed on a skin target and modulating the applied vacuum, the concentration of blood and/or blood vessels is increased within a predetermined depth below the skin surface of the skin target. Optical energy associated with light directed in a direction substantially normal to a skin surface adjoining the skin target is absorbed within the predetermined depth. The apparatus is suitable for treating vascular lesions with a reduced treatment energy density level than that of the prior art and for evacuating condensed vapors produced during the cooling of skin. The vacuum chamber may also have a skin flattening transmitting element which inhibits pain transmission upon applying a sufficiently high vacuum.Type: GrantFiled: April 11, 2006Date of Patent: August 10, 2010Assignee: Candela CorporationInventor: Michael Slatkine

Patent number: 7762965Abstract: A method and apparatus are disclosed for enhancing the absorption of light in targeted skin structures. A vacuum chamber having a clear transmitting element transparent to intense pulsed light on its proximate end and an aperture on its distal end is placed on a skin target. After applying a vacuum to the vacuum chamber and modulating the applied vacuum, the concentration of blood and/or blood vessels is increased within a predetermined depth below the skin surface of the skin target.
