Abstract

The present invention provides a bone fixation device for implantation into the intramedullary canal of a bone. The bone fixation device may include a support structure and a thermo-chemically activated matrix. The support structure may be radially expandable and contractible, and sufficiently flexible to be inserted into the intramedullary canal through an opening which is not parallel to the intramedullary canal. The matrix may attain a first thermo-chemical state via the addition of energy, and a second thermo-chemical state via the dissipation of energy. While in the first thermo-chemical state, the matrix is deformable and can conform to a shape matching the contours of the intramedullary canal of the bone. As the matrix attains the second thermo-chemical state, it may crystallize and becomes relatively hardened. An implant deformation apparatus may be used to expand the device within the intramedullary canal. The device may include a series of nested telescoping components.
