Abstract
The present invention relates to a biodegradable tubular device for angioplasty treatment of vascular sclerosis in general and of coronary disease in particular, without inducing the complications that may possibly be encountered when a permanent device of the stent type is fitted. The property of controlled biodegradability of the device according to the invention, combined with the characteristics of the material used, significantly reduces the post-surgical risks of recurrence of functional complications (restenosis, thrombosis and the like) or of infectious diseases originating near the angioplasty device. The shape and texture of the tubular device permit an adjustment of diameter by virtue of its property of elasticity.
