The present invention relates to a minimally invasive apparatus and method of use to correct varicose veins by sclerosis. The apparatus comprising a semi-flexible first catheter having a proximal end, a distal end, and an outer surface. The first catheter also has a lumen area extending the length of the catheter and capable of receiving a guide wire. The proximal end is fitted to receive an inflation device and/or a closure device. At the distal end, a collapsible occlusive balloon is attached. Additionally, the apparatus has a second catheter having a proximal end, a distal end, an outer surface. The second catheter also has a lumen area extending the length of the second catheter. The second catheter has a larger lumen than the first catheter, allowing the first and second catheters coaxial alignment. The distal end of the second catheter adapted to from a sealing engagement with the periphery of the first catheter, allowing the second catheter to movably extend over and retract from the first catheter. Attached to the second catheter is a reservoir for dispensing a treatment agent into the lumen. The second catheter is adapted to connect to the reservoir. The treatment agent is dispensed to the vein via one or more side openings.
