Espire™ Pro

I do not have enough reliable information about Steeper Group's Espire Pro to give a verified product history. I can identify it as an upper-limb prosthetics line with powered elbow functionality, but I cannot confirm its launch year or any discontinuation date from my current knowledge.

Because of that, I am leaving the timeline empty rather than guess. If you want, I can still help by summarizing the product family from the description you provided, but not as a sourced historical record.
