Liquidmetal Technologies Inc (LQMT)

Since you asked, and at the risk of being lambasted for providing an opinion not backed by links... I think the staple IS the liquidmetal part due to the following qualities of liquidmetal:
• strength despite very thin part size (that can slide smoothly through the tendon sheath)
• elasticity that allows the part to flex thousands of time without deformation
• corrosion resistance
• complexity of shape possible without machining
And, to your point, it's not yet FDA-approved, right?
