Abstract

SISTEMA DE LIBERAçãO CONTROLADA DE SONDAS E ENXERTOS. A presente invenção provê um mecanismo de liberação para encaminhamento, por acesso percutâneo, de uma endoprótese ('sonda") ou enxerto, através do sistema vascular, e procedimentos para o tratamento de um aneurisma ou de um vaso com outro tipo de lesão. O sistema de liberação inclui um cateter-guia tubular externo 20, um cateter tubular interno de liberação (impulsor) 14, disposto coaxialmente, em relação ao cateter-guia externo, e podendo deslizar, e um fio ou cabo flexivel alongado 26, que pode ser inserido coaxialmente através do lúmen do cateter tubular interno e que possui um isolador algo cónico preso na extremidade distal do mesmo, dimensionado para ser, pelo menos parcialmente, ajustado dentro do lúmen do cateter interno impulsor, quando uma força de tensão é aplica entre o fio ou cabo flexível alongado 26, em orientação proximal, em relação ao cateter impulsor 14. Pela inserção de uma mola de espirais, comprimida entre uma parte da extremidade proximal do cateter impulsor 14 e a parte da extremidade final do cabo 26, a força de fixação necessária é mantida para prender o stent ou enxerto à extremidade distal do cateter impulsor ate que força de compressão da mola seja removida. Com o stent ou enxerto preso à extremidade distal do cateter interno impulsor, ele pode ser puxado dentro do lúmen do cateter-guia externo para liberação com o mesmo até o sítio pretendido.
