Abstract
Se describe un aparato y un método para la remocion no invasiva de tejidos objetivo. El aparato incluye un arreglo de elemento de antena de aplicador de microondas (20) para introducir una pluralidad de ondas superficiales electromagnéticas cilíndricas, casi transversales adyacentes al tejido objetivo. A través de desviaciones de fase sucesivas, las ondas superficiales electromagnéticas son llevadas a conveger sobre un punto focal dentro del tejido objetivo, elevando por lo tanto la temperatura del tejido. En una aplicacion el aplicador de microondas se usa para reducir el tejido graso dentro de una capa de grasa subcutánea tomando en cuenta las diferntes constantes dialéctricas de las capas de piel y musculo adyacentes. Lanzando una onda atrapada entre la capa de piel y las capas de musculo, se produce una onda cilondrica convergente que incluye una columna de alta densidad a lo largo de una línea que se extiende desde la interfaz de la grasa cutánea hasta la interfaz de la grasa muscular. El efecto de la columno de alta densidad es elevar la temperatura de las células adiposas a un nivel al cual ocurre necrosis de los adipositos. En operacion, un bolo de infriamiento (34) acoplado al aplicador mantiene activamente la temperatura de la superficie de la piel por debajo de un nivel al cual ocurre daño celular o heridas incomodas.
