This statement from the NPRM seems to indicatate that we might not see use 
of this out in the open vs. a permanant implant.
"The Notice proposes to limit MMN operations to use only by persons for 
diagnostic and therapeutic purposes, and only to the extent provided under 
the direction of authorized health care professionals."
