Patent ID: 8287538

Claim:
An apparatus for treating a fracture of a bone, the fracture including segments, the bone having an inner cavity, the apparatus comprising: a structural support for positioning a first of the bone segments relative to a second of the bone segments, the structural support being configured to be deployed in the inner cavity; an anchoring substrate configured to maintain a position of the first bone segment relative to the second bone segment, the anchoring substrate being configured to be deployed in the inner cavity; a proximal anchor that is configured to secure a proximal portion of the anchoring substrate to the bone; and, when the proximal anchor has a center axis, a detent configured to fix the distal end of the proximal anchor, with respect to the center axis, to the structural support; wherein: the proximal anchor is substantially cylindrical and comprises blades that extend radially outward; the proximal anchor includes a proximal end and a distal end; the blades move radially outward when the proximal and distal ends are moved toward each other; and the proximal end of the proximal anchor is configured to be pushed distally to move the blades radially outward.
