Title (EN) MEDICAL INSERT
(FR) INSERT MÉDICAL
Abstract:
(EN) The invention provides a catheter comprising an elongate body having an exterior surface with a substantially planar portion, a perforation that extends through the planar exterior surface to an internal lumen, providing fluid communication between the lumen and said surface, and a movable covering to occlude the perforation when the catheter body is moved relative to brain tissue during insertion and withdrawal from said tissue. The invention extends to a method of removing excess cerebrospinal fluid from a patient through use of the catheter. The coverings fold according to the direction of movement to cover an adjacent trailing perforation against ingress of tissue fragments.
(FR) L'invention concerne un cathéter comprenant un corps allongé ayant une surface extérieure avec une partie sensiblement plane, une perforation qui s'étend à travers la surface extérieure plane jusqu'à une lumière interne, assurant une communication fluidique entre la lumière et ladite surface, et un revêtement mobile pour fermer la perforation lorsque le corps de cathéter est déplacé par rapport au tissu cérébral pendant l'insertion et le retrait dudit tissu. L'invention s'étend à un procédé d'élimination d'un excès de fluide cérébrospinal d'un patient par l'utilisation du cathéter. Les revêtements se plient selon la direction de déplacement pour protéger une perforation arrière adjacente contre l'entrée de fragments de tissu.
