ABSTRACT:
A method and apparatus for reducing the thickness of arterial walls is disclosed. Ablation of the exterior layer of the arterial walls is performed using mechanical or laser ablation techniques. Surveying is preferably carried out during the procedure to ensure optimal ablation. The ablation reduces the effective thickness of the arterial walls and increases flexibility so that the walls distend under normal blood pressure, thereby improving blood flow. Advantageously, the procedure is carried out without invasion of the blood vessel lumen and without damage to the inner layer of the artery wall.
