Abstract

"IMPLANTE MéDICO QUE TEM CIRCUITO DE REGULAçãO DE TRANSFERêNCIA DE ENERGIA DE TRANSFERêNCIA DE ENERGIA TRANSCUTâNEA (TET) DE LAçO FECHADO". A invenção refere-se a um dispositivo médico implantável, tal como um dispositivo infusor bidirecional para controlar hidraulicamente um esfíncter artificial (por exemplo, uma cinta gástrica ajustável) que beneficia-se de ser remotamente impulsionado por transferência de energia transcutânea (TET), prevenindo a necessidade de baterias. Para que os componentes ativos no dispositivo médico operem, um sinal de energia senoidal recebido por uma bobina secundária é retificado e filtrado. Uma quantidade de energia transferida é modulada. Em uma versão, uma comparação de voltagem é feita de uma voltagem de suprimento de energia resultante como referenciada a um limite para controlar a modulação de largura de pulso (PWM) do sinal de energia senoidal recebido, conseguindo a regulação de voltagem. Versões incorporam dessintonizar ou desacoplar a bobina secundária para conseguir o controle de PWM sem causar um excessivo aquecimento do dispositivo médico.
