Publication number: 20120150189Abstract: Disclosed is a method of selecting a femoral prosthetic for implantation relative to a femur using a femoral sizing guide. An extension portion of the femoral sizing guide is placed adjacent to a posterior condyle surface of the femur. A stylus is located proximate to an interior condyle surface of the femur. A first actuator disposed between the extension portion and a base portion is moved to rotatably displace the extension portion with respect to the base portion until the stylus is centrally located on top of the interior condyle. A measurement of the femur is identified with the sizing guide based on a relative location of the stylus, the extension portion and the base portion. A femoral prosthesis is selected based on the measurement.Type: ApplicationFiled: February 21, 2012Publication date: June 14, 2012Applicant: BIOMET MANUFACTURING CORP.Inventors: Robert G.

Patent number: 8142342Abstract: A device for separating components of a composition according to density. The device includes a rotatable chamber and a plurality of buoys. The rotatable chamber has an axis of rotation. The plurality of buoys are positioned within the rotatable chamber and about the axis of rotation. The buoys are radially movable between an expanded position in which the buoys are at a first location relative to the axis of rotation and a contracted position in which the buoys are at a second location relative to the axis of rotation. The first location is further from the axis of rotation than the second location is. The buoys are movable in response to force generated during rotation of the rotatable chamber.Type: GrantFiled: September 1, 2011Date of Patent: March 27, 2012Assignee: Biomet Biologics, LLCInventor: Jacy C.
