摘要：
Devices and transdermal methods are provided for safe and effective therapeutic treatment of the venous system, such as varicose veins. Present invention provides non-invasive and minimally invasive transdermal methods for treating varicose and spider veins, comprising the use of a radiation source in combination with a chemical fluid/composition to safely and more effectively close or shrink vein walls, providing a transdermal therapeutic method for varicose veins until now only treated with surgery or endovascular laser treatments. In a preferred embodiment a device comprises a radiation source, preferably of wavelength between about 980 and 1940 nm, being effective in causing shrinkage of the vein treated. In other preferred embodiments methods comprise the transdermal delivery of a chemical composition through a patch or gel or the injection of a chemical fluid, preferably a hypertonic solution, to the vein under treatment； and simultaneously or after a dwell time, irradiating with a radiation source transdermally. The treatment performed with the present invention results in blood vessel wall damaged, eventually closing the vein, in lesser time with practically no pain or discomfort to the patient during and after the therapy.
