A balloon dilation catheter includes a distal monorail section, to which a balloon is secured, and a catheter body tube including a monorail section. A guide tube extends through the balloon and has a proximal end sealed to a guide wire port in the body tube. A guide wire extends along the body tube and through the guide tube. To stiffen the body tube while maintaining maximized fluid flow area, a stainless steel hypotube extends through the proximal body tube, has a distal opening positioned adjacent the guide wire port and a solid reinforcing tapered distal end section that extends across the guide port. The hypotube can be fixed or removable. Alternatively, the hypotube divides the interior of the proximal body tube section into two separate flow passages to enable positive purging.
Cathéter à ballonnet comprenant une section distale monorail à laquelle est fixé un ballonnet et une tubulure formant le corps du cathéter comprenant une section monorail. Une tubulure-guide traverse le ballonnet et son extrémité proximale est scellée à un orifice pour le fil-guide dans le corps de la tubulure. Un fil-guide longe le corps de la tubulure et à travers le fil-guide. Pour maintenir la tubulure rigide tout en assurant un volume maximal pour l'écoulement de liquide, un hypotube en acier inoxydable traverse la tubulure proximale, présente une ouverture distale adjacente à l'orifice du fil-guide et une extrémité distale profilée de renforcement qui passe en travers de l'orifice du fil-guide. L'hypotube peut être fixe ou amovible. L'hypotube peut aussi diviser l'intérieur de la partie proximale de la tubulure en deux canaux d'écoulement distincts afin de permettre une purge positive.
