Abstract

dispositivo médico para uso em curto tempo com agente antibacteriano rapidamente liberável. a presente invenção refere-se a um processo para provimento de um dispositivo médico com atividade antimicrobiana, compreendendo as etapas de: provimento de um material substrato revestido com um polímero hidrofílico, o dito polímero hidrofílico exibindo uma baixa fricção quando umedecido; provimento de uma solução coloidal compreendendo partículas quimicamente reduzidas de um metal oligodinâmico e um polímero hidrofílico, o dito polímero hidrofílico sendo o mesmo como no revestimento do material substrato; e imersão do dito material substrato na solução. um dispositivo médico preparado da mesma maneira também é mostrado. através deste processo, propriedades muito vantajosas do revestimento antibacteriano são obtidas. em particular, uma taxa de liberação relativamente baixa é obtida no fluido de umedecimento, e uma taxa de liberação relativamente alta é obtida na situação de uso pretendida , por exemplo, quando inserido na uretra.
