摘要：A bone fixation device is provided with an elongate body having a longitudinalaxis and having a first state in which at least a portion of the body is flexible and a second
state in which the body is generally rigid, an actuatable gripper disposed at a distallocation on the elongated body, a hub located on a proximal end of the elongated body,and an actuator operably connected to the gripper to deploy the gripper from aretracted configuration to an expanded configuration. Methods of repairing a fracture ofa bone are also disclosed. One such method comprises inserting a bone fixation deviceinto an intramedullary space of the bone to place at least a portion of an elongate bodyof the fixation device in a flexible state on one side of the fracture and at least a portionof a hub on another side of the fracture, and operating an actuator to deploy at least onegripper of the fixation device to engage an inner surface of the intramedullary space toanchor the fixation device to the bone. Various configurations are disclosed for allowing adevice body to change shape as it moves from a flexible state to a rigid state.
