After receiving a shipment of Parylene coated magnets, I once again had one implanted. After some discussion, we decided to try a slightly different approach. We theorized what went wrong and adjusted the implantation method to better the chances of a successful healing. I made a nifty diagram to illustrate:
Note: The bevel of the needle in the diagram on the right is not in the proper orientation. It was actually rotated 90 degrees so that the pointy long side was facing my fingernail.
The first time, which ultimately ended up rejecting, is on the left. The needle was inserted as shown, making a pocket close to the surface. As the wound healed the magnet was pushed out with the help of gravity and the lubricity of Parylene.
This time we went straight into the side, deeper into the tissue with no angle to the cut. There was more bleeding this time, which made the magnet a bit tricky to get inside. The suture was probably the most uncomfortable part of the procedure (the black squiggle I drew on the diagram), but I really think it's the key to getting this implant healed properly.
I've now started the healing process once again, and am being extra careful not to stress the area or expose it to any strong magnetic fields. With any luck everything will go smoothly and I will be feeling fields in no time!
