There is a company [can not name them now, so please do not ask**] that has licensed my PEMF technology to build such a device and market it on a global scale. The strict terms of the license should keep them honest. If not, they lose the rights.
So, we will see if it is possible for anyone to market anything globally without being dragged to the Dark Side.
Timeline?: It takes a long time to develop a physical product, something like 18 to 24 months at least.
** Why the confidentiality? If you announce things before you are ready, you come under relentless attack by every PEMF-marketer scumbag around the globe, so, if you want anything honest and fair to succeed, you need to keep it far away from the dirt-bags who thrive on sucker punching the very few honest fair dealers before they are ready to defend themselves.
