Abstract
A blood vessel such as a varicose vein is removed using a semi-rigid rod attached to a flexible thread. The thread is passed through the vein using the rod, which can then be removed. An end of the vein is affixed at a point between the ends of the thread, for example the midpoint. By pulling on the thread, the end of the vein is drawn back into the lumen of the vein, and the vein is progressively turned inside out. A stop can be fixed to the thread slightly beyond the point at which the vein is affixed to the thread, and prevents slipping along the thread. The thread can be at least twice as long as the vein, and alternately pulled in opposite directions.
