Abstract
L'invention concerne un système pour réaliser une angioplastie, qui comprend un cathéter à ballonnet (1) muni d'un ballonnet (10) pouvant être rempli d'un fluide électriquement conducteur et de deux électrodes (12, 13) disposées dans le ballonnet (10), et une unité d'évaluation (14) reliée électriquement aux électrodes (12, 13). L'unité d'évaluation (14) est conçue pour appliquer au moins un signal d'excitation (U) aux électrodes (12, 13) et pour mesurer au moins un signal de mesure (I) par l'intermédiaire des électrodes (12, 13) afin de déterminer à l'aide dudit au moins un signal de mesure (I) des valeurs d'impédance (Z1, Z2) à des fréquences différentes et de déterminer une valeur caractéristique corrélée avec la résistance électrique du fluide dans le ballonnet (10).
