Embodiment Construction

[0043]One embodiment of the present invention provides a catheter-based vapor therapy system that generates vapor at a distal end. The distal tip of the catheter is small enough to fit not only within the GSV, but also the smaller blood vessels within the patient's leg. The vapor therapy system may be used to treat varicose veins or for reduction therapy. Vapor generating catheters according to this embodiment can be made with diameters in the range of 4 Fr to 10 Fr, which can be used to treat a common range of veins and / or vessels, including GSVs and main branches emanating therefrom, since the diameter of the catheter is easily adapted in these blood vessels. However, in other embodiments, the catheter may be greater than 10 Fr or less than 4 Fr.

[0044] One aspect of the vapor therapy system according to this embodiment is the heat source at the distal end of the catheter that causes the vapor phase change of the liquid, particularly the size and efficiency of the heat s...

Abstract

Methods and apparatus for generating vapor within a catheter are provided which may include any number of features. One feature is generating vapor with an electrode array within a catheter. Another feature is sensing an impedance of the electrode array, and adjusting the power delivered to the electrode array to fully generate vapor within the catheter. Another feature is delivering the vapor to a vein of a patient for vein reduction therapy.
