ELAN is a new method for treating atherosclerotic vessels. Its purpose is to restore the wall flexibility by removing arterial wall tissue from the outer arterial layer. This leads to expansion of the narrowed vessel resulting in an increased blood flow. We present results of treatment of arteries in vitro. The Tissue removal was done by excimer-laser ablation using ns-pulses of 193nm wavelength. We also discuss two possible methods for therapy control. OCT images and light diffusion measurements are presented.
