Abstract

"MONTAGEM DE CATETER E PROCESSOS PARA ULTRAPASSAR E PARA FRATURAR UMA OCLUSãO VASCULAR". é divulgado aqui uma montagem de extremidade rombuda que inclui um cateter e um elemento de extremidade rombuda. O elemento de extremidade rombuda inclui seções de mandíbula, que tem uma primeira posição fechada para localizar o elemento de extremidade rombuda no local da oclusão dentro do lúmen nativo do vaso sang³íneo e uma segunda posição aberta na qual as seções de mandíbula são capazes de pressionar contra as paredes interiores do lúmen adjacente à oclusão. O conjunto inclui um elemento de atuação para mover as seções de mandíbula das posições fechada para aberta repetidamente, resultando em um faturamento da oclusão. Um fio de guia pode ser rosqueado através de uma abertura interna no cateter e no elemento de extremidade rombuda e, depois da fratura, através da oclusão.
