A balloon catheter having a proximal end and a distal end and a main axial lumen extending therebetween is provided with an inflation seal such that the presence of a guidewire in the inflation seal forms a fluid-tight seal for retaining fluid in the balloon and causing inflation thereof. The inflation seal can be formed distally of the balloon or within the balloon. Marker bands disposed at the distal end are formed integrally with the structure of the balloon catheter.
L'invention concerne une sonde à ballonnet comprenant des extrémités proximale et distale, et une lumière axiale principale s'étendant entre lesdites extrémités. Ladite sonde comporte un joint étanche de dilatation caractérisé en ce que la présence d'un fil guide dans ledit joint entraîne la formation d'un joint étanche servant à retenir un fluide dans le ballonnet et occasionnant une dilatation de ce dernier. Le joint étanche de dilatation peut être formé distalement par rapport au ballonnet ou à l'intérieur de celui-ci. Des bandes de marquage placées à l'extrémité distale sont incorporées à la structure de la sonde à ballonnet.
