Is this really a year old post? It was a good read regardless.
To comment on the topic, this is going to happen more and more, especially as proprietary stuff becomes more and more complex. With implants it's obviously more serious, but this also applies to anything from cars to game consoles.
I'm no stranger to scrounging junkyards for car parts or ebay to replace components from an old console. However that cannot go on forever, as parts get more rare. This is somewhat remedied with eg. nintendo consoles, where some reproduction parts are available (cartridges, screens etc.). With more niche and increasingly complex products this option is often not available.
