Publication number: 20160262904Abstract: An expandable implant includes an implant body defining an internal void, the implant body including a plurality of interconnected linkages. A first plurality of the linkages has an expansion characteristic that is different from a second plurality of the linkages. An expandable bladder is sized to be disposed in the internal void. The bladder defines a bore configured to receive an expansion material, such that the expansion material applies an expansion force against the bladder, which thereby applies the expansion force against the implant body so as to cause the first linkage to expand greater than the second linkage. The expandable implant can be placed in a fracture location so as to restore height to a fractured target bone.Type: ApplicationFiled: May 25, 2016Publication date: September 15, 2016Inventors: Konrad Schaller, Beat Lechmann, Robert Frigg
