Given that MED-EL, the company mentioned in the article, has been around since 1990 and is constantly expanding, I would assume that this is indeed viable.<p>I live in Innsbruck, Austria, where MED-EL is headquartered. Like most people I know, I too have briefly worked there in 2008. I currently live 5 minutes on foot from where the entrance <i>used to be</i> back then, before it was walled off, they massively expanded the building and added another building behind it, where in 2008 a bunch of office containers with clean rooms used to be. There is now a raised walk way to the other side where they used to rent just a few units back then and now co-opted the building, plus a patch work of smaller rental spaces all around.<p>The implants themselves are <i>not cheap</i> and (at least at the time?) eventually needed to replaced. From what I recall, some of the technology involved was also licensed out or sold for other applications. Ultimately, I would also guess that all the licensing, approval and red-tape involved in actually making implants for humans also kind of limits competition quite a bit.
