Abstract: A medical device for capturing one or more physiological variables of a patient is described. The medical device includes a housing, a display device mounted on the housing, and ports on the housing for connecting one or more peripheral sensors. The medical device receives data from the peripheral sensors, processes the data to calculate at least one physiological variable, and displays the at least one physiological variable on the display device. The medical device monitors an internal temperature inside the housing, determines whether the internal temperature exceeds a predefined threshold, and when the internal temperature exceeds the predefined threshold, perform one or more actions to lower the internal temperature.

Abstract: A method for improving the development of an initial surgical plan includes receiving input information, developing an initial surgical plan based upon the input information, and allowing a user to customize the initial surgical plan by providing input related to modifications to the initial surgical plan. The method further includes storing information related to the modifications to the initial surgical plan and using the stored information to develop a subsequent initial surgical plan based on the modifications.

Abstract: A method for guiding a user during surgical planning includes receiving input information; applying an algorithm to the input information to develop an initial surgical plan; and guiding a user by providing a plurality of suggested actions to the user. If the user performs the plurality of suggested actions, the plurality of suggested actions leads the user to the initial surgical plan. The user has an option to deviate from one or more of the plurality of suggested actions by performing non-suggested actions. Deviation from one or more of the plurality of suggested actions leads to development of a final surgical plan that is different from the initial surgical plan.

Abstract: A knee arthroplasty prosthesis includes a femoral component having multiple pieces with engagement means provided for engaging various pieces of the femoral component to one another following their insertion in the incised area of the femur. A tibial component includes multiple pieces designed for assembly following positioning in the incision. The tibial component includes a Morse taper cavity on one piece of the tibial component and a Morse taper extension on another member of the component for receipt therein.

Abstract: The present invention comprises a set of instruments and a method for their use in preparing a knee joint to receive knee implants. The inventive instruments and method are generally suitable for knee joint surgery. Furthermore, they include features that make them suitable for performing a minimally invasive knee surgery in which a smaller than normal incision is made and oriented to preserve the quadriceps mechanism and protect the suprapatellar pouch. The instruments permit switching from a minimally invasive technique to a standard open technique at any point in the procedure. An illustrative set of instruments for total knee arthroplasty and an associated minimally invasive technique are described.

Abstract: A method and apparatus for performing total knee arthroplasty which is minimally invasive includes components with guide surfaces and slots for controlling the path of a cutting saw. The instrumentation permits resection of the proximal end of the tibia and distal end of the femur to be performed either medially or laterally with minimal cutting of soft tissue.

Abstract: A femoral knee saw guide for use in surgery includes a cutting guide having a slot extending therethrough for guiding a saw and alignment structure attached to the guide and positioned externally of the patient's femur for effecting proper alignment of the cutting guide. The cutting guide may be used for cutting one or both condyles at the distal end of the femur in a medial to lateral direction or lateral to medial direction. An arm having a stylus extending into the plane defined by the path of travel of the saw may be used when it is desired to cut only a single condyle to prevent inadvertently cutting the opposing condyle.
