This invention relates to a catheter comprising a tube-like basic body with a proximal and a distal end, at least one balloon member arranged close to the distal end, which can be expanded from a deflated state in which the balloon member has a small diameter to an inflated state in which the balloon member has a larger diameter. The catheter also comprises means for supplying a fluid under pressure to the balloon member in order to expand the latter, wherein the balloon member has, at least in the deflated state, a surface structure incorporating differences in height.

L'invention porte sur un cathéter constitué d'une base en forme de tube, avec une extrémité proximale et une extrémité distale, et au moins un ballonnet situé près de l'extrémité distale, pouvant être dilaté à partir d'un état dégonflé, où le ballonnet a un petit diamètre, jusqu'à un état gonflé, où le ballonnet a un grand diamètre.
