Abstract
(EN)
Systems and methods utilizing RF energy to treat a patient's skin or other target tissues are provided herein. In various aspects, the methods and systems described herein can provide a RF-based treatment in which RF energy can be selectively controlled to facilitate heating uniformity during one or more of body sculpting treatment (lipolysis), skin tightening treatment (laxity improvement), cellulite treatment, all by way of non-limiting examples. In various aspects, the systems may include a flexible applicator comprising a plurality of layers, the plurality of layers comprises a first dielectric layer, a second dielectric layer, and a conductive layer, wherein the first dielectric layer and the second dielectric layer sandwich the conductive layer, the plurality of layers define a plurality of kerfs, an inner region and N regions extending from the inner region, wherein the plurality of kerfs divide the applicator into N regions.

L'invention concerne des systèmes et des procédés utilisant l'énergie RF pour traiter la peau d'un patient ou d'autres tissus cibles. Selon divers aspects, les procédés et les systèmes décrits ici peuvent apporter un traitement basé sur RF dans lequel l'énergie RF peut être sélectivement commandée pour aider à garantir l'uniformité du chauffage pendant un ou plusieurs traitements parmi le traitement de sculpture du corps (lipolyse), le traitement de resserrement de la peau (amélioration de la laxité), le traitement de la cellulite, tous étant donnés à titre d'exemples non limitatifs. Dans divers aspects, les systèmes peuvent comprendre un applicateur flexible comprenant une pluralité de couches, la pluralité de couches comprenant une première couche diélectrique, une seconde couche diélectrique et une couche conductrice, la première couche diélectrique et la seconde couche diélectrique prenant en sandwich la couche conductrice, la pluralité de couches définissant une pluralité d'entailles, une région interne et N régions s'étendant à partir de la région interne, la pluralité d'entailles divisant l'applicateur en N régions.
