Abstract

"APARELHO MéDICO E MéTODO úTIL PARA POSICIONAMENTO DE DISPOSITIVO PARA DISTRIBUIçãO DE ENERGIA". A presente invenção refere-se a um aparelho médico e a um método úteis para o tratamento térmico eficaz de lúmen, tal como velas varicosas durante a cirurgia a laser. Um dispositivo para distribuição de energia, compreendendo uma fibra ótica difusora com uma seção emissora de luz e um dispositivo de memória tendo dados nele programados também é proporcionado. A fibra ótica inclui um sensor de temperatura para medir uma temperatura em um local de tratamento. Um gerador de energia é conectado à fibra ótica e a um dispositivo de posicionamento. A fibra ótica encaixa o dispositivo de posicionamento de modo que o dispositivo de posicionamento pode posicionar movelmente a seção emissora de luz da fibra ótica . Conseq³entemente, a fibra ótica pode ser inserida diretamente em uma posição apropriada dentro de uma porção varicosa de uma veia ou outro lúmen para tratamento térmico da veia. O dispositivo de memória e um processador principal são usados para controlar automaticamente a operação do aparelho médico, incluindo a intensidade de energia emitida e movimento ou posição da seção emissora de luz da fibra ótica dentro da veia que está sendo tratada.
