[TCML] Safety Issue for sternal wires in heart bypass patients

[pterren at iinet.net.au]

The sternal wires are of no consequence. They are often inserted in a twice 
around figure 8 and the ends twisted. It looks crude on xray.
Here are single loops (blue arrows):

These are more like knitting:

They are not connected with the heart and if anything will act to trap AC 
fields by a limited Faraday cage effect.
Heating will not be a significant effect. The body is conductive and will 
have some "skin effect".

Now a pacemaker is a slightly different situation...

But if his sternum is wired shut, won't he have a mini receiver coil inside 
of him? Even so, probably the worst that could happen is it would get warm, 
but who knows. I have seen wrenches on my bench arc to one another from 10 
feet away from my small coil. Of course, combing my hair in the winter 
lights up pretty good in the dark.

Maybe you could ask the surgeon whether the wire is a continuous coil, or a 
series of shorted turns, then build a mockup and see what happens.

Hi Jeff,

Well, I'm no doctor, but it's my understanding
that the main issue with Tesla coils vs. heart pa-
tients is when they have an installed pacemaker,
which obviously has sensitive electronics. I per-
sonally can't see where being in the near proximity
of an operating Tesla coil poses any "additional"
hazard to a recovering heart bypass patient than it
would to anyone else, other than that he/she would
likely be in a weakened cardic condition during the
recovery process. However, keep in mind that like I
said, I am NOT a medical professional, nor do I claim
any competant medical knowledge thereof. However,
it is my understanding that one of our fellow list
members, one Peter Terren (Tesla Downunder),
does happen to be a medical doctor, so maybe he
would like to chime in with some truely "profes-
sional" advice regarding this subject mater.?

Hello,
This may sound like an off the wall question but I need to know.
My brother and myself were working on a 1.6kva tesla coil.  He will be going 
in surgery this morn for bypass surgery. After the surgery they will be 
wiring he sternum closed with SS wire. For his sake, would it be wise for 
him to leave the project and not be around while operation the tesla .
