Apparatus and method for inhibiting pain signals transmitted during a skin related medical treatment
Patent number: 7740600Abstract: An apparatus adapted to inhibit pain signals generated by pain receptors in the skin during a skin related medical treatment such as an injection. An evacuation chamber is provided with an essentially rigid interface element larger than a threshold surface area through which a medical treatment can be administered to a selected skin region, one or more walls which are placeable in the vicinity of the skin region, an interior defined by the walls and by the interface element, and an opening at the bottom of the interior which is sealable by the skin region. A device generates a vacuum within the evacuation chamber interior to a level greater than the threshold vacuum level suitable for drawing the skin region through the opening towards, and in a compressing relation against, the interface element, to inhibit the transmission of a pain signal generated by pain receptors located within the skin region.Type: GrantFiled: August 3, 2006Date of Patent: June 22, 2010Assignee: Candela CorporationInventors: Michael Slatkine, Raphael Shavit -
Patent number: 7740651Abstract: An apparatus for treating skin includes a chamber defined by a surface and a rim extending from the surface. A source of vacuum is capable of removing air from inside the chamber so that air outside the chamber flows into the chamber. Impedance of the air flowing between the rim of the chamber positioned adjacent the skin surface causes the pressure inside the chamber to decrease relative to ambient. A pressure sensor can determine when the pressure inside the chamber decreases to a threshold value. A controller can receive a signal from the pressure sensor when the threshold value is reached, which causes the rate of removal of the air from inside the chamber by the source of vacuum to be increased. The rim of the chamber forms a substantially fluid tight seal with the skin. The skin is drawn toward an inner surface of the chamber.Type: GrantFiled: September 28, 2007Date of Patent: June 22, 2010Assignee: Candela CorporationInventors: Menashe Barak, Shlomi Mishali, Raphi Shavit, Michael Slatkine

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
