I have a couple questions regarding the flexibility (or rather, the durability) of the FlexM1 and similar format implants: if you implant it in a slightly fleshy spot - as opposed to along a bone - it’ll bend when you press down on it. That means the copper wire in the coil will bend. My questions are these:
If the fleshy bit is fleshy enough, and you press hard enough, does the copper wire deform permanently? Copper isn’t very springy, so I expect it to deform plastically each time the device is subjected to bending.
Have you done a metal fatigue test? I.e. how many times can you bend it until the wire breaks, and how does the amount of bending reduce the number of cycles?
Have you noticed delamination or shearing between the top or bottom of the flexible silicone and the embedded inflexible copper in the middle, as the device is flexed repeatedly?
