Here is something else interesting; if you go to wikipedia and look up this company you will see where they are responsible for creating what is called, neuromodulation devices. Meaning, they are able to install extremley small neuros inside a certain part of the body to help stop pain. If they can do that, is it possible they can place something else within the body, and we not know about it.

From Article.
"Neuromodulator Injections Neuromodulators commonly come in the form of injectables. Once inserted into the skin, the neuromodulators prevent facial muscles from moving. The injections freeze and relax the muscles."

Excellent informational response!
