Abstract

<B>"MéTODO E DISPOSITIVO PARA APREFEIçOAR DRENAGEM DE HUMOR AQUOSO EM UM OLHO".<D> A presente invenção refere-se a um método para aperfeiçoar a drenagem de humor aquoso em um olho com o canal Schelmam, em cujo olho o humor aquoso secretado pelo corpo ciliar é drenado através de trajetos de escoamento subsequentes e a um dispositivo para manter a drenagem do humor aquoso. Por meio de um injetado na forma de um líquido hidrofílico ou um meio gasoso biocompatível ou uma mistura de líquido hidrofílico e do meio gasoso dentro do canal Schelmamm (15) micricirurgicamente exposto em um ou mais locais, o canal de Schlemm (15 é localmente expandido por meio de pressão hidráulica aumentada. Com o elemento de suporte (35) subsequentemente implantado no lúmem (16) (16) do canal de Schlemm (15), as paredes internas deste canal são suportadas e permanentemente mantidas na posição expandida, pelo que a drenagem não-impedida do hunor aquoso a partir do canal de Schlemm (15) através de trejetos de escoamento subsequentemente (20) é garantida.
