My smashed finger injury has gotten much, much better. The area doesn't feel quite back to normal, but has the familiar "almost healed" feeling to it. It appears the implant survived a pretty hard test, which is one more victory for Parylene coating.
I have gotten several e-mails asking about where to get the magnets or if I would sell them. I honestly don't know if I'm ready to hand them to just anyone, but at the same time I recognize that others are just as willing as I was to have one put in. It's likely that I will start an eBay store and sell packs of 4 or 5 magnets for close to cost. Before I do, I'll get a pictorial of how mine were installed and a general set of guidelines for handling, sterilizing them, and examining them for flaws.
I will say this, though I have said it before. This is a very experimental procedure in which you are implanting an object in to yourself that could potentially be harmful. These magnets are not designed originally for implantation. While you can take every precaution to handle and install them correctly, there is a definite possibility of a compromised coating, and you may be forced to remove fragments of magnet from your finger, or worse. These are risks that myself and the others that have tried have understood from the beginning.
That being said, I think that this is a body modification that has been on the verge of explosion for quite awhile. Purpose-made parylene coated magnets and implantation tools could make this procedure accessible to many, and just may encourage others to find ways to give humans more sensory perception through body modification.
