Claims16
Mid-foot osteotomy device, comprising a biocompatible implant having a wedge shape configured to be placed between adjacent bones post-osteotomy, the wedge-shaped biocompatible implant has a pre-implant angle and a post-implant angle, the post-implant angle is expandable and configured to provide gradual correction over time post-implant, and inflation chamber within the wedge-shaped biocompatible implant and a fluid conduit communicating with the inflation chamber, wherein the inflation chamber is configured to expand the wedge-shaped biocompatible implant from the pre-implant angle to the post-implant angle under the influence of a fluid input from the fluid conduit to the inflation chamber.
An osteotomy implant, comprising a wedge-shaped member having a central annular opening, the wedge-shaped member having a taper configured to be placed between adjacent bones post-osteotomy;
- and an inflation chamber within the wedge-shaped implant, wherein the wedge-shaped implant has a taper that is capable of being expanded from a first angle to a second angle upon introducing of a fluid into the inflation chamber.
