Abstract

L'invention concerne l'analyse de la physiologie de la paroi d'un vaisseau par décalage de fréquence intervenant dans un oscillateur (21) suite à des variations de capacité d'un condensateur établi entre une plaque métallique (12) supportée par un cathéter (10) et une partie adjacente de la paroi du vaisseau où l'on insère le cathéter (10). Les variations de capacité propres à ce condensateur variable sont décelées par le décalage de fréquence d'un oscillateur à fréquence variable (21) mélangé avec la sortie d'un oscillateur à fréquence fixe (23).
