How Are Pacemakers Made?

Mr. Johnson knows...


Hi, Kim:

My name is Delos. I thought about droping my last name so everyone would think I was cool . . .you know, like Iman, Chantal, Sting and Kim. Decided against it though, it's hard enough having to explain about 'Delos,' imagine what I would go through if I had to explain why I did not have a last name!!

You asked about how pacemakers are made. I am really not sure how to answer that question, but I will try. My company is located in Sylmar, CA (you may want to try to find that on a *good* map of CA ). It is near Los Angeles. Actually it is located near an amusement park called "Magic Mountain." Inside the company there are many large "clean rooms." A clean room is one where all the air is filtered so that there is no lint or bad germs in it. The people who work in the clean room have to dress in special lint free clothing from the top of their heads to the bottom of their feet. Do you know that, at the end of the day, the bottoms of their shoe covers are not even dirty because the rooms are so clean.

Special machines make the pacemaker cans and headers (ask Danielle what those are) for the people in the clean room to assemble. Most of the assembly work is done by hand, but some of the very difficult welding and soldering and other assembly is assisted by computer. Each person in the clean room has a special job and the pacemaker is passed from person to person.

Once the device is completely finished it is placed in a special tesing machine to make sure that it is working properly. It is visually inspected and the log books (log books are the record of the assembly) are reviewed. If every thing is O.K., the pacemaker is put in a special sealed container and sterilized using a gas called ethelene oxide. Two days after it comes out of sterility it is placed in its final boxes (two or three of them) and sent to wait to be used. Do you know that every step of the manufacturing process is recorded in the log books? Why do you think they would have to do that? Why do you think we use a gas instead of heat to sterilize the pacemaker?

Sorry to be so boring with the description. There is nothing very exciting about manufacturing a pacemaker - except the welding (they use laser beams).

I hope you will keep writing to me. I enjoy watching your eyes get droopy when you read the answers to the questions.
