I guess you mean a 'port' such as used for dialysis. I don't know a lot about them but they are - as I understand them - a long term subcutaneous device used by piercing it with a needle while treating. If it was active during the debate there would need to be some sort of pump and I would think a rigid needle to pierce the port, but that is where my knowledge breaks down. When it comes to high level high tech cheating I suppose we are all grasping at straws.
As to the 'wire' - it may just be the wire from a 'wireless' debate mike to the small transmitter placed under his clothing ... or maybe not(?)
