Abstract
La présente invention concerne un nouveau type de cathéter à ballonnet utilisé l'angioplastie percutanée par ballonnet de valve pulmonaire guidée par ultrasons, ayant trait au domaine de traitement interventionnel. Le cathéter à ballonnet comporte un cathéter et trois ballonnets disposés sur le côté extérieur dudit cathéter; les ballonnets sont manchonnés sur ledit cathéter, produisant un joint d'étanchéité; les trois ballonnets sont, consécutivement, un ballonnet de guidage (1), un ballonnet de dilatation (2), et un ballonnet de positionnement (3); à l'intérieur du cathéter sont prévus quatre passages séparés disposés en parallèle dans le sens longitudinal du cathéter; chacun des ballonnets correspond à un joint d'étanchéité unique et est manchonné sur le côté extérieur de l'ouverture de chaque passage situé au niveau de la paroi latérale, formant des espaces étanches expansibles qui sont séparés les uns des autres et n'entraînent pas d'interférence mutuelle. Le ballonnet de guidage se dilate après le gonflage, et sa superficie de section transversale augmente de manière significative en comparaison avec la superficie de la section transversale du cathéter; à ce moment, une sonde à ultrasons peut facilement détecter la position du ballonnet, ce qui facilite la détermination de la position de l'extrémité supérieure du cathéter. Par conséquent, lors de l'utilisation de la structure de cathéter à ballonnet selon la présente invention pour effectuer une angioplastie, des ultrasons peuvent être efficacement utilisés pour le guidage, évitant les effets nuisibles entraînés par l'utilisation de rayonnement pour le guidage.
