A catheter (30), and method for treating a target region in a body lumen comprising directing a uniform dose of ultrasonic energy from an interior of the lumen, wherein the dosage of ultrasonic energy received at any one point along the length varies by no more than plus or minus 6 decibels. One catheter (30) has an array of transducers (20) which emit ultrasound energy in directions (D1, D2).
L'invention se rapporte à un cathéter (30) et à un procédé de traitement d'une région cible d'une lumière corporelle. Ledit procédé consiste à diriger une dose uniforme d'énergie ultrasonore depuis l'intérieur de ladite lumière, la puissance de l'énergie ultrasonore reçue en n'importe quel point de la longueur ne variant que dans une fourchette de plus ou moins 6 décibels. Un cathéter (30) possède un réseau de transducteurs (20) qui émettent une énergie ultrasonore dans des directions (D1) et (D2).
