Device, a catheter, and a method for the curative treatment of varicose veins

Abstract

Described herein are a device and a method for the treatment of varicose veins via laser radiation, and in particular using a holmium laser. The radiation of a laser source ( 5 ) is injected in a fiber ( 3 ) that can be inserted in the vessel to be treated. The laser source emits a radiation such as to cause a hyalinizing sclerosis with structural modifications both to the fibers of the collagen (shrinkage) and to the extracellular matrix of the median coat of the vein by the photothermal effect, substantially without thermal stress of the morphological component of the tunica media and of the tunica intima.

Description

technical field [0001] The invention relates to innovations in the field of varicose vein treatment. More particularly, the present invention relates to specific and innovative catheters for this type of treatment, as well as devices or devices for treatment and methods of treatment. Background technique [0002] Varicose veins refer to one of the most common chronic pathological conditions that progress to the need for surgical intervention. It is a typical pathological condition in more developed countries and has considerable socioeconomic impact. It is prevalent in fact, affecting up to about 10% of the general population. For example, in the United States, approximately 25 million people are affected by varicose veins, of whom approximately 2.5 million suffer from chronic venous insufficiency (CVI) and 500,000 have ulcerative lesions. [0003] Varicose veins are more prevalent in women (50-55%) than men (10-50%), with annual incidence rates of 2.9% and 1.6%, respecti...
