Abstract

CATETER MELHORADO COM PONTA óTICA OMNI-DIRECIONAL TENDO CAMINHOS óTICOS ISOLADOS. A presente invenção refere-se a um cateter que permite medições de luz em tempo real, por exemplo, sem limitação, a refletância difusa, fluorescência, etc., a partir dos materiais biológicos, tais como tecido (incluindo sangue), enquanto se realiza a ablação por RF. A configuração da ponta do cateter isola os trajetos de iluminação e de coleta dentro do eletrodo de ponta para que a luz para iluminar o tecido de interesse (por exemplo, tecido cardíaco ou sangue) seja isolada dentro do eletrodo de ponta a partir da luz que retorna a partir do tecido para a ponta de cateter, e vice versa. A referida configuração evita de forma vantajosa a saturação do detector ótico, e garante a difusão da luz de iluminação dentro do meio de interesse. O cateter apresenta um corpo de cateter e um eletrodo de ponta com uma parede de invólucro e uma cavidade oca. A parede de invólucro apresenta pelo uma abertura de iluminação e uma abertura de coleta. O cateter adicionalmente inclui um primeiro cabo de fibra ótica em comunicação com a abertura de iluminação, e um segundo cabo de fibra ótica em comunicação com a cavidade oca, onde a luz emitida a partir do primeiro cabo de fibra ótica sai pelo eletrodo de ponta para alcançar o tecido através da abertura de iluminação definindo um primeiro trajeto e retorna para o eletrodo de ponta a partir do tecido e dentro da cavidade oca através da abertura de coleta definindo um segundo trajeto, os primeiro e segundo trajetos sendo oticamente isolados um do outro dentro do eletrodo de ponta. A presente invenção inclui também um método de produção da ponta de eletrodo de ablação que define trajetos óticos isolados com um eletrodo de ponta para a luz que sai do eletrodo de ponta e para a luz que retorna do eletrodo de ponta.
