Abstract

"MéTODO E SISTEMA PARA LIBERAçãO ELETROCINéTICA DE UMA SUBSTâNCIA". Um sistema eletrocinético (300) para liberação de uma substância em tecido inclui uma fonte de corrente alternada (308) de uma freq³ência predeterminada. Um primeiro eletrodo é acoplado a um primeiro terminal da fonte de corrente alternada e um segundo eletrodo é acoplado a um segundo terminal da fonte de corrente alternada. Um circuito retificador é acoplado entre o primeiro eletrodo e o primeiro terminal da fonte de corrente alternada. Um dos primeiro e segundo eletrodos é adaptado para contato elétrico com um local de liberação de substância. Uma corrente retificada pelo circuito retificador escoa em um caminho de corrente, entre os primeiro e segundo eletrodos, quando um dos primeiro e segundo eletrodos está em contato elétrico com o local de liberação de substância, para fazer a liberação da substância no tecido.
