Less traumatic angioplasty balloon for arterial dilatation
First Claim
1. A less traumatic angioplasty balloon for arterial dilatation of the type inflatable by means of respective lumens existing in a catheter used for the introduction of the balloon, the catheter and balloon defining a longitudinal axis, characterized in that the balloon has a unitary construction and the surface of the fully inflated balloon that contacts the endothelium of the vessel being treated is an irregular surface defining a plurality of elongate grooves and projecting parts interspersed therebetween.
