It's called the V-Nus closure fast procedure. The treatment uses a long electrode which is threaded up the vein.
Then radio frequency waves heat the vein until it collapses and closes. One patient described the feeling in her legs before the surgery.
"They'd just hurt - it was a heaviness, a density about the lower limbs," said patient Christine McLaughlin.
"Typically patients feel better right away almost, as they walk out they feel lighter that they no longer have that heavy pressure inside the veins," said Dr. Mark Adelman from New York University.
It takes 15 minutes and there is no anesthesia, no pain and no painful recovery.
This was at New York University, but doctors across the country, including some in the Bay Area, are using this technique.
