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. Jones, James C. Hsia, Dilip Y. Paithankar

Patent number: 9486285Abstract: Treating skin can include delivering a beam of radiation to a target region of the skin to cause a zone of thermal injury including a lateral pattern of varying depths of thermal injury distributed along the target region. The lateral pattern includes at least one first sub-zone of a first depth of thermal injury laterally adjacent to at least one second sub-zone of a second depth of thermal injury. The first depth is greater than the second depth. The at least one first sub-zone of the first depth and the at least one second sub-zone of the second depth extend from a surface of the target region of the skin to form a substantially continuous surface thermal injury. The at least one first sub-zone of the first depth and the at least one second sub-zone of the second depth are substantially heated to at least a critical temperature.Type: GrantFiled: August 13, 2012Date of Patent: November 8, 2016Assignee: CANDELA CORPORATIONInventors: Dilip Y.

Publication number: 20090187169Abstract: Disclosed herein is a method of treating mammalian, for example, human, skin afflicted with a sebaceous follicle disorder, for example, acne. The method involves cooling an exposed surface of a region afflicted with the disorder and applying light, for example, light from a coherent or incoherent light source, to the region. The applied light reduces the size and/or density of lesions associated with the disorder in the treated region, and can reduce or otherwise alleviate lesion-associated skin inflammation in the treated region. Cooling preserves the surface, for example, epidermis, of the skin. The method, therefore, is effective at treating the disorder while at the same time avoiding or minimizing thermal damage to the exposed surface of the skin.Type: ApplicationFiled: March 30, 2009Publication date: July 23, 2009Applicant: Candela CorporationInventors: Anthony J. Durkin, Dilip Y. Paithankar, Yacov Domankevitz

Publication number: 20080215040Abstract: Treating biological tissue can include selecting parameter for electromagnetic radiation based on at least one parameter of a target region within the biological tissue. Treating biological tissue also includes methods, systems, and kits for delivering the electromagnetic radiation through a surface of the biological tissue to the target region to induce within the target region a sub-surface thermal injury characterized, for example, by a desired degree and a desired depth and confining the sub-surface thermal injury to substantially within the target region.Type: ApplicationFiled: March 3, 2008Publication date: September 4, 2008Inventors: Dilip Y. Paithankar, Christopher J. Jones, James C. Hsia

Patent number: 6743222Abstract: Disclosed herein is a method of treating mammalian, for example, human, skin afflicted with a sebaceous follicle disorder, for example, acne. The method involves cooling an exposed surface of a region afflicted with the disorder and applying energy, for example, energy from a coherent or incoherent light source, to the region. The applied energy reduces the size and/or density of lesions associated with the disorder in the treated region, and can reduce or otherwise alleviate lesion-associated skin inflammation in the treated region. Cooling preserves the surface, for example, epidermis, of the skin. The method, therefore, is effective at treating the disorder while at the same time avoiding or minimizing thermal damage to the exposed surface of the skin.Type: GrantFiled: December 7, 2000Date of Patent: June 1, 2004Assignee: Candela CorporationInventors: Anthony J.

Patent number: 5865754Abstract: A system and method non-invasive biomedical optical imaging and spectroscopy with low-level light is described. The technique consists of a modulated light source (120) coupled to tissue (100) of a patient to introduce excitation light. Fluorescent light emitted in response to the excitation light is detected with sensor (148). The AC intensity and phase of the excitation and detected fluorescent light is provided to a processor (160) operatively coupled to sensor (148). Processor (160) employs the measured re-emission kinetics of excitation and fluorescent light to "map" the spatial variation of one or more fluorescence characteristics of the tissue (100). The fluorescence characteristic may be provided by exogenous contract agents, endogenous fluorophores, or both. The variation is determined by solving frequency domain diffusion equations at a number of designated points in the tissue as part of a recursive estimation algorithm.Type: GrantFiled: August 23, 1996Date of Patent: February 2, 1999Assignee: Purdue Research Foundation Office of Technology TransferInventors: Eva M.
