Patent number: 8287539Abstract: 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.Type: GrantFiled: June 10, 2009Date of Patent: October 16, 2012Assignee: Sonoma Orthopedic Products, Inc.Inventors: Charles L.

Patent number: 8066639Abstract: 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.Type: GrantFiled: June 4, 2004Date of Patent: November 29, 2011Assignee: Abbott Diabetes Care Inc.Inventors: Charles L. Nelson, Mark K. Sloan, Robert Y. Jin, Feng Jiang, Jen-Chyun Chen, Arthur Eugene Anderson, III, Charles T. Liamos, Douglas C. Limbach

Publication number: 20080140078Abstract: 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.Type: ApplicationFiled: November 21, 2007Publication date: June 12, 2008Applicant: SONOMA ORTHOPEDIC PRODUCTS, INC.Inventors: Charles L.
