Parylene coated pacemaker

Is anyone familiar with parylene coated pacemakers? I am supposed to have a pacemaker implanted later this month that is parylene coated. According to Wikipedia, "it is the most bio-accepted coating for stents, defibrillators, pacemakers and other devices permanently implanted into the body."

My autoimmune problems are suspected to be the result of a 17 year history of leaking silicone implants, which were removed due to systemic symptoms.

Please post if you have any information.

Thank you,.

Vapor Deposited

I'm an engineer with a certain gov agency (four letters) and we've used parylene or paraxylene for years. We use it to coat electronics. It is a very tough coating as long as you don't get it above 125C. I've tested it in our lab under extreme conditions and it has held up well. It is vapor deposited which means it gets in cracks and crevices very well - sometimes a little too well. I don't know anything about it in regards to in body use. I didn't know it was used as a coating for pacemakers. Thanks for the info. I'll ask one of our materials scientists about it next week and see if he knows about its use in body.

Thank you. I would appreciate any information you might be able to find.

I am of the opinion that the human body attempts to reject some materials. I had a lot of trouble adjusting to the pacemaker that was implanted 2 years ago. The resulting flareup of autoimmune symptoms has calmed down somewhat, but not nearly like it had before it was implanted.

Thank you,

Parylene Use

Talked to my friend who is more familiar with parylene chemically and he is familiar with its use in body. He said the reason it is used is because of its long term stability. He is not aware of any problems. Hopefully, you won't react to it.

It may be the first time we've felt a normal heart rhythm in a long time, so of course it seems too fast and too strong.
