  • 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.

  • Patent number: 8066639
    Abstract: A glucose measuring system includes a glucose meter that incorporates wireless communication capabilities. The meter can advantageously be a low cost meter by eliminating expensive components, such as the display. The user nevertheless is able to retrieve and view his or her glucose values by referring to displays within the glucose measuring local area network. Feedback via these displays can advantageously be used by the diabetic to create a higher level of confidence and safety.

  • Patent number: 7942875
    Abstract: A method of repairing a bone fracture comprises accessing a fracture along a length of a bone through a bony protuberance at an access point near an end of a bone. A bone fixation device is advanced into a space through the access point at the end of the bone. A portion of the bone fixation device is bent along its length to traverse the fracture. The bone fixation device is locked into place within the space of the bone.

  • Publication number: 20080140078
    Abstract: The invention is generally directed to tools, systems and methods of preparing a bone site prior to deployment of bone repair devices. In one embodiment, a bone cutting instrument is provided with a generally rigid arcuate tube having a generally fixed radius and a lumen therethrough, a flexible drive shaft configured to be slidably and rotably received within the tube lumen, and a cutter head attached to an end of the drive shaft, whereby the shaft and cutter head may be first advanced together with the tube in an arcuate manner to cut an arcuate path in a bone, and then advanced in a telescoping manner relative to the tube being held in a generally fixed position to cut a straight path in the bone. Methods of forming a passage in a bone include advancing a cutter head into a bone along a curved path having a generally constant radius, and continuing to advance the cutter along a generally straight path extending from the curved path.
