Abstract

"MéTODO, DISPOSITIVO E CATETER PARA DETERMINAR IN VIVO PROPRIEDADES DO SANGUE TAL COMO SUA VISCOSIDADE". A invenção se refere a um método para a determinação das propriedades do sangue, tal como a viscosidade do sangue de um indivíduo, compreendendo a geração in vivo durante,um determinado tempo, por meio de uma corrente elétrica alternada de uma determinada freq³ência, de um sinal da medição da impedância do sangue entre pelo menos dois pontos localizados centralmente em um volume de sangue, onde o sinal de medição é processado tal que as variações que nele ocorrem devido a uma freq³ência da ordem da magnitude da freq³ência cardíaca estão substancialmente ausentes dele, e comparar o processado sinal da medição com as relações predeterminadas entre a impedância e as propriedades do sangue, tal como a viscosidade.
