A minimally-invasive surgery apparatus for causing the lumen of a vein to collapse to prevent blood flow through the vein, e.g., a varicose vein or a side branch of the saphenous vein, includes an electrode which is electrically connected to a power source, and the electrode is percutaneously advanced into the vein. Then, the power source is activated to energize the electrode and thus the blood vein until the blood vein sufficiently collapses to block the lumen of the vein. A feedback loop is also provided for sensing electrical impedance of the tissue within the vein being energized and for deenergizing the electrode when the impedance reaches a predetermined value. The apparatus can also be used to block a fallopian tube.
