So the procedure is being shown to have the same success as open stripping but the tolerance is better. Patients don't have to have general anesthesia. They have a single needle stick to enter the vein. And how can the patient endure higher than boiling water temperatures? It's because we actually numb up the vein with about on average seven to 11 needle sticks along the vein in which we actually infiltrate a local anesthesia to numb up the vein. So they won't feel this pain. And I can assure you this pain is zero. This is a pain-free procedure, other than the needle sticks that are fairly ameliorated by the fact that they have a sedative on board. We do these procedures in people as early as in their thirties to people in their nineties who are healthy enough to have this procedure and who are severely bothered by this without any problems. And the success is quite similar than open stripping in the past.
