"In any other area of vascular surgery, we have now new technologies being applied to this problem. And there's about three that come to mind that are new and in development at this moment. I explained that for this procedure to be painless, we have to do about seven to 10 needle sticks along the thigh of the patient to numb up the vein. Well, now scientists have created intravenous glue. And so what you do is to shut down the system. You don't apply the heat anymore. You apply a, let's call it a cement, that will go from the shallow area and you're growing all the way down. And obviously just injecting cement is painless. And so in theory, the first studies are showing similar success with the application of heat and all the risks that that conveys versus just applying cement. Now you think about it. I'm not sure what you rather have for you. You're applying heat, but there's nothing foreign introduced to your body. Whereas now you're introducing a foreign exogenous substance like cement. God only knows that that cement will break and move in the future, that so far is not seen, but that could be seen. There's another device that has been created, which does two things: injects some sort of a glue or a sclerosing substance. So it's an, it's an irritation to the vein, but also there's a helix at the end that moves like this, as you provide the catheter, and damages the inner lining of the vein, and we have discussed before how damaging anything inside the vein can be. And by damaging the vein, you are causing that vein to shut down. And in this case, that's what you want. Cause that veins is at fault. That vein is not working well. So by damaging the inner lining and applying this glue, you are in theory, shutting it down. And once again, this is painless. You don't need to do the anesthesia. It's called tumescent anesthesia. And you are basically getting rid of that step, which is sometimes painful to patients. So those are new things on both. Those are new things that'll be in research at this point. There's some insurance issues that are being dealt with at this point. Whereas insurance companies are not reimbursing practices for the performance of the new procedures and the more data is collected. And so, but once again, there's the steps that industry and science takes are towards less and less invasive, better procedure with the same outcomes."
