Title
(EN) SYSTEMS AND METHODS FOR SHUNTING FLUID
(FR) SYSTÈMES ET PROCÉDÉS DE DÉRIVATION D'UN FLUIDE
Abstract
(EN)
Systems and methods are provided herein that generally involve shunting fluid, e.g., shunting cerebrospinal fluid in the treatment of hydrocephalus. Self-cleaning catheters are provided which include split tips configured such that pulsatile flow of fluid in a cavity in which the catheter is inserted can cause the tips to strike one another and thereby clear obstructions. Catheters with built-in flow indicators are also provided. Exemplary flow indicators include projections that extend radially inward from the interior surface of the catheter and which include imageable portions (e.g., portions which are visible under magnetic resonance imaging (MRI)). Movement of the flow indicators caused by fluid flowing through the catheter can be detected using MRI, thereby providing a reliable indication as to whether the catheter is partially or completely blocked. Systems and methods for flushing a shunt system are also disclosed herein, as are various systems and methods for opening auxiliary fluid pathways through a shunt system.

La présente invention concerne des systèmes et des procédés qui impliquent de manière générale la dérivation d'un fluide, par exemple la dérivation d'un liquide céphalo-rachidien dans le traitement d'une hydrocéphalie. L'invention concerne des cathéters auto-nettoyants comprenant des pointes fendues conçues de sorte qu'un écoulement de liquide pulsatile dans une cavité dans laquelle est inséré le cathéter peut amener les pointes à se toucher et ainsi éliminer les obstructions. L'invention concerne également des cathéters comprenant des indicateurs de débit intégrés. Des indicateurs de débit donnés à titre d'exemple comprennent des parties saillantes qui s'étendent radialement vers l'intérieur à partir de la surface intérieure du cathéter et qui comprennent des parties visibles par imagerie (par exemple, des parties qui sont visibles par imagerie par résonance magnétique (IRM)). Le mouvement des indicateurs de débit provoqué par l'écoulement d'un liquide à travers le cathéter peut être détecté par IRM, ce qui permet d'obtenir une indication fiable pour savoir si le cathéter est partiellement ou complètement bloqué. L'invention concerne également des systèmes et des procédés de rinçage d'un système de dérivation, tels que divers systèmes et procédés d'ouverture de passages de liquide auxiliaire par l'intermédiaire d'un système de dérivation.
