What is a defibrillator made out of?

My mum has a defibrillator and had it approx 18 years ago I'm trying to find out what it's made out of and if it might have mercury in it?

Does your mum know the manufacturer of the ICD as you can contact them direct for information. ICD's are completely sealed units, we've attend lots of icd support meetings & I can't recall anyone ever mentioning mercury.

I used to work with medical sensors. The ones I used were external devices and had hi-grade sealed thermoplastic cases. Because ICDs are internal the casing is made of titanium. The units are powered by lithium batteries. The circuitry, like smart phones, will contain some rare metals but I cannot see how mercury would come into the equation.

I had a quick check mercury featured in the zinc-mercury batteries used in early pacemakers 40 years ago. These small batteries were first developed in WWII.

Hi There,

I was wondering what makes you think there could be Mercury in it.

I would hope that if there was your mum would have been told.

I'd ask her to check with her heart consultant / nurse for a definitive answer though.
