System zum Behandeln von Krampfadern

摘要

A system for the application of thermal energy in order to cause permanent contraction of vascular structures comprises a catheter (1) and a control device (2). The catheter (1) is introduceable into a vascular structure and includes at least one lumen having an opening in the distal end region. The control device (2), to which the catheter (1) is connectable via its proximal end region (5), is adapted to provide a liquid, to cause heating of the liquid and to supply the liquid into a lumen of the catheter (1) and to apply a vacuum to a lumen of the catheter (1).
