Objective: Implantable technologies should be mechanically compliant with the tissue in order to maximize quality and reduce inflammation during reconstruction. We introduce development of a flexible expandable implantable robotic (FEIR) device for regenerative elongation tubular by applying controlled precise tension target while minimizing forces produced on surrounding tissue. Methods: theor...
