Abstract

Dispositif médical gonflable et technique pour la mise en place d'un extenseur dans un vaisseau de l'organisme par expansion en deux temps de l'extenseur et pour l'administration de médicaments en un point précis du vaisseau. Le dispositif comprend une tige de cathéter (14) comportant plusieurs canaux intérieurs (13, 22, 28). L'extrémité distale de la tige de cathéter peut être introduite dans un vaisseau. Un ballon gonflable, délimité par une paroi sensiblement cylindrique, est conçu pour recevoir un fluide de gonflage. Le ballon est placé à l'extrémité distale de la tige. La paroi du ballon comporte un réseau de tubes de gonflage (40) disposés de façon circulaire. Ces tubes (40) sont éloignés les uns des autres dans la paroi de façon à former une structure annulaire. On peut placer un réseau de tubes (25) d'administration de médicaments dans la paroi du ballon. Ces tubes sont conçues pour amener des médicaments en des points prédéterminés des vaisseaux à traiter. Un extenseur (30) amovible, placé à l'extérieur de la paroi du ballon, peut se gonfler de façon radiale vers l'extérieur pour passer d'un faible diamètre d'insertion à un deuxième diamètre plus important, par expansion du ballon (16), puis à un troisième diamètre encore plus important par gonflement des tubes de gonflage (40), de façon à dilater le vaisseau et à positionner l'extenseur.
