G. Lynn Rasmussen has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10517583
    Abstract: A combination of a first assembly for guiding resection of a femur and tibia of a knee joint and a second assembly including femoral and tibial knee components. The combination of the first assembly and the second assembly provides optimal placement and positioning of the femoral and tibial knee components to achieve near-normal knee kinematics and tension. The preparation for and placement of the prosthetic knee components provides medial-pivoting kinematics mimicking that of the natural knee thereby promoting improved outcome for the patient.

  • Patent number: 10398450
    Abstract: Methods for resecting a portion of a knee joint are described herein. While the described methods can comprise any suitable step, in some implementations, the methods include cutting a cylindrically-shaped hole in a portion of the knee joint selected from at least one of a distal portion of a femur and a proximal portion of a tibia in the knee joint; and using a depth of the cylindrically-shaped hole as a reference point to resect bone around the cylindrically-shaped hole to a depth substantially matching the depth of the cylindrically-shaped hole. Other implementations are described.

  • Publication number: 20190046217
    Abstract: A tibial baseplate is described. While the baseplate can include any suitable component, in some instances, it includes a first surface and a second surface, the second surface being substantially opposite to the first surface and the first surface being configured to be seated on a resected surface at a proximal end of a tibia. In some cases, the baseplate also includes a first spacer coupling that is configured to couple a first spacer to at least one of a lateral side and a medial side of the baseplate such that the spacer is disposed between, and is configured to maintain a set minimal distance between, the proximal end of the tibia and a distal end of a femur when the tibial baseplate is seated on the resected surface at the proximal end of the tibia and the spacer is coupled to the tibial baseplate. Other implementations are discussed.

  • Publication number: 20170128078
    Abstract: An assembly for guiding resection of a femur and tibia of a knee joint in preparation for installing a femoral and tibial knee components. For example, the assembly can include tibial and femoral IM rods to which are connected through a tensioning bolt that allows controlled adjustment of the distraction of the tibia and femur during cut positioning in a range of flexion angles. Also, the assembly is usable with relatively small, noninvasive approaches to the knee joint by way of relatively narrow, low profile components that attach to tibial and femoral IM rods. Further, the assembly includes several quick-release components to allow fast assembly and disassembly in a surgical setting. Each of these aspects, along with the ability of the assembly to accurately guide initial reference cuts to the tibia and femur, promotes an improved outcome for the patient.

  • Publication number: 20170024545
    Abstract: Systems and methods for providing graphical information regarding one or more patients' medical information are described. The graphical information can be used in various methods of graphical comparison, including graphical diagnoses, graphical comparison between patients, over time with a single patient, and/or over time with and/or between multiple patients. The graphical information can be used in place of and/or in conjunction with existing methods and systems for conveying medical information, including one or more textual methods and systems. The graphical information is provided electronically to any electronic or computer device or is provided in hard copy, such as a part of a patient's chart. The use of graphical patient medical information permits rapid and improved conveyance of information, and improves recognition and understanding of the most relevant medical information.

  • Patent number: 9149284
    Abstract: A milling tool system for accurately preparing a portion of the tibia preparatory to making femoral resections. The milling tool system provides a minimally invasive procedure to provide an aperture within an exposed surface of the tibia, the aperture then being used as a referencing surface to accurately resect the femur. Once the femur resections have been made, the remaining uncut portions of the tibia are exposed and easily accessible for the tibial resections.
