Abstract

L'invention concerne un procédé chirurgical permettant d'élargir une lumière artérielle complètement bouchée par une lésion sténosée, ainsi que le cathéter à ballonnet d'un type unique utilisé pendant cette opération. Le cathéter à ballonnet (70) a, en général, la forme d'une tige et il comprend un élément tubulaire (76) allongé pourvu d'une double lumière centrale ayant une extrémité proximale et une extrémité distale, ainsi que d'une partie à ballonnet (74) ayant une pointe distale (121) concave dont le diamètre est plus petit que celui de la pointe proximale (126). Le procédé tire avantage de la conception du cathéter et comprend l'étape de positionnement du cathéter à proximité immédiate de la plaque créant l'occlusion totale, et de façon stable par rapport à celle-ci, et l'opération de gonflage du ballonnet pour former une ouverture dans la plaque créant l'occlusion.
