Конструкция и технология получения ультразвуковых концентраторов-волноводов трубчатого типа для устранения непроходимости кровеносных сосудов

Abstract

Fundamentally new design of ultrasonic waveguide-catheter system to eliminate the obstruction of blood vessels was developed. The effect thrombus/plaques destruction is carried out by using a cavitation jet of liquid formed by supplying through internal cavity of concentrator-waveguide at its distal part simultaneously with ultrasound action. This kind of effect, unlike mechanical cavitation is more effective and safer in terms of destruction of endovascular thrombi and atherosclerotic plaques, and has greatly improved elastic-mechanical properties of the vascular wall in atherosclerosis and diabetes.
