  • the present invention relates to an apparatus for preventing departure of a cerebrospinal fluid transport conduit having an improved structure.
  • Hydrocephalus refers to a condition in which excessively accumulated cerebrospinal fluid expands the ventricles or increases pressure in the cranial cavity due to blocked outflow of cerebrospinal fluid or an imbalance in the production and absorption of cerebrospinal fluid.In children, hydrocephalus is caused by congenital malformations. It may also occur for acquired reasons, such as cerebral hemorrhage, infection, or brain tumor.

Abstract

La présente invention concerne un dispositif permettant d'empêcher la déviation d'une dérivation de fluide céphalorachidien. Le dispositif empêchant la déviation d'une dérivation de fluide céphalorachidien, selon la présente invention, est destiné à fixer fermement une dérivation qui permet au liquide céphalorachidien de se déplacer entre un ventricule cérébral et l'intérieur de la cavité abdominale. Ce dispositif comprend : une partie bride interne qui est ajustée dans un trou devant être formé dans une paroi abdominale formant la cavité abdominale et ayant un trou traversant qui est en prise avec une surface interne de la paroi abdominale définissant le trou et à travers lequel passe la dérivation; une partie bride externe qui est en prise avec une surface externe de la paroi abdominale définissant le trou et a un trou traversant formé sur le même axe que le trou traversant; et une partie de fixation qui est disposée entre la partie bride interne et la partie bride externe et qui est positionnée dans le trou à former dans la paroi abdominale et qui fixe la dérivation insérée dans celle-ci.
