  • Patent number: 8568413
    Abstract: A bone fixation device is provided with an elongate body having a longitudinal axis 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 actuateable gripper disposed at one or more locations on the elongated body, a hub located on a proximal end of the elongated body, and an actuator operably connected to the gripper(s) to deploy the gripper(s) from a retracted configuration to an expanded configuration. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a bone fixation device into an intramedullary space of the bone to place at least a portion of an elongate body of the fixation device in a flexible state on one side of the fracture and at least a portion of a hub on another side of the fracture, and operating an actuator to deploy at least one gripper of the fixation device to engage an inner surface of the intramedullary space to anchor the fixation device to the bone.

  • Patent number: 8439917
    Abstract: A bone fixation device is provided with an elongate body having a longitudinal axis and having a flexible state and a rigid state, a plurality of grippers disposed at longitudinally spaced locations of the elongated body, a curved rigid hub connected to the elongated body, and an actuator operably connected to the grippers to deploy the grippers from a first shape to an expanded second shape. Methods of repairing a fracture of a bone are also disclosed. One such method comprising inserting a bone fixation device into an intramedullary space of the bone to place at least a portion of an elongate body of the fixation device in a flexible state on one side of the fracture and at least a portion of a curved rigid hub on another side of the fracture, and operating an actuator to deploy a plurality of grippers of the fixation device to engage an inner surface of the intramedullary space to anchor the fixation device to the bone.

  • Publication number: 20130116693
    Abstract: A straight intramedullary bone fracture fixation device is provided with an elongate body having a longitudinal axis for deployment in a long bone, such as a clavicle. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a bone fixation device into an intramedullary space of the bone to place at least a portion of an elongate body of the fixation device on one side of the fracture and at least a portion of a hub on another side of the fracture, and engaging an inner surface of the intramedullary space to anchor the fixation device to the bone. Various configurations and designs may be used in combination with other fixation device components.

  • Publication number: 20130012942
    Abstract: A segmented bone fixation device is provided with an elongate body having a longitudinal axis 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. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a segmented fixation device into an intramedullary space of the bone to place at least a portion of the fixation device in a flexible state on one side of the fracture, providing rigidity across the fracture, and operating an actuator to deploy at least one gripper to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Various configurations allow a segmented device body to change shape as it moves from a flexible state to a rigid state.

  • Patent number: 8287539
    Abstract: A bone fixation device is provided with an elongate body having a longitudinal axis 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 actuateable gripper disposed at a distal location on the elongated body, and an actuator operably connected to the gripper to deploy the gripper from a retracted configuration to an expanded configuration. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a bone fixation device into an intramedullary space of the bone to place at least a portion of an elongate body of the fixation device in a flexible state on one side of the fracture and at least a portion of a hub on another side of the fracture, and operating an actuator to deploy at least one gripper of the fixation device to engage an inner surface of the intramedullary space to anchor the fixation device to the bone.
