Abstract

Procédé et système permettant de traiter des anévrismes par application d'énergie haute fréquence sur du collagène. On place un cathéter à proximité de l'anévrisme et on exsude du collagène dans l'anévrisme ou à son voisinage. On applique sur le collagène de l'énergie haute fréquence à l'aide du même cathéter ou d'un deuxième cathéter ceci ayant pour effet de durcir le collagène qui recouvre la partie affaiblie de la paroi du vaisseau sanguin et devient alors un substrat sur lequel peuvent se développer des cellules épithéliales du vaisseau sanguin. Le cathéter est constitué d'un cathéter électrophysiologique comportant une électrode annulaire placée de préférence de manière à libérer une énergie haute fréquence comprise entre environ 5 et environ 30 watts à une fréquence comprise préférablement entre environ 450 et environ 600 megahertz pour appliquer suffisamment d'énergie sur le collagène pour que ce dernier durcisse sans pour autant endommager les tissus voisins.
