Hi,
I live in Spain. I have heard about a new technique. Its name is POSE an endoscopic technique, reversible and minimally invasive. With no device implanted.
I don't know anybody who had this technique done.
It is supposed to be very popular among spanish doctors but I need more information.
For example in Valencia (a mediterranean city) the cost is 12.000euros / 16.600 $, is expensive but maybe is worth the effort.
Here you have a piece of news where it is said that spanish doctors use it very often.
