Abstract

"sistema e método minimamente invasivos para monitorar níveis de analito". trata-se de um dispositivo detector de analito minimamente invasivo (100) e um método para usar o mesmo. o sistema e o método empregam um dispositivo que tem um eletrodo ativo (104) opcionalmente revestido com uma substância (126) e um contra-eletrodo (106) que é configurado para circundar, pelo menos parcialmente, o eletrodo ativo (104). a configuração do eletrodo auxiliar (106) e do eletrodo ativo (104) aperfeiçoa o fluxo de corrente através do dispositivo (100) e aumenta a sensibilidade do dispositivo. quando o dispositivo é colocado de encontro à pele do paciente, o eletrodo ativo (104) é adaptado para entrar, através do córneo do paciente, até uma profundidade inferior à profundidade na derme à qual as terminações de nervo residem. um potencial elétrico é aplicado ao eletrodo ativo (104) e o nível do analito é determinado com base na quantidade de corrente ou carga que flui através do dispositivo.
