  • Publication number: 20210178027
    Abstract: This present invention relates to drug eluting polymers, including novel biodegradable drug eluting polymers, which are added to the surface of a medical device to treat device associated complications and to deliver drug locally around the device. Methods of making polymers, for example, drug-eluting polymers, polymer compositions, and materials used therewith also are provided. The drug eluting polymers are obtained from the polymerization of macromonomers made of a connecting moiety, a biodegradable moiety and a cross-linkable moiety that are liquids at a temperature of 10° C. to 40° C.

  • Publication number: 20180116809
    Abstract: The present invention provides a femoral prosthesis for a femur which can enable or allow deep knee flexion without creating excessive tension in the ligamentous structure of the knee. The femoral prosthesis includes an internal non-articulating surface, an external articulating surface, a medial condyle and a lateral condyle. The height of the medial condyle is less than the height of the lateral condyle. A proximal-posterior tip of the medial condyle is rounded and is shifted inwards relative to the native level of the proximal-posterior region of the femur bone to facilitate knee flexion. A method of mounting a femoral prosthesis on a femur is also described.

  • Publication number: 20170273799
    Abstract: Methods and devices are provided for knee joint replacement with anterior cruciate ligament (ACL) substitution. Generally, the methods and devices can allow a knee joint to be partially or totally replaced in conjunction with substitution of the knee joint's ACL. In one embodiment, a knee replacement prosthesis can include a medial or lateral femoral implant, a femoral intercondylar notch structure, a medial or lateral tibial insert, and an ACL-substitution member. The ACL-substitution member can be configured to engage with the femoral intercondylar notch structure during a full range of knee motion and/or during only early knee flexion.

  • Publication number: 20170135610
    Abstract: Systems and methods provide patient position information to a user. A patient positioning device is placed on a patient in a predefined location. The patient positioning device determines a relative patient position with respect to at least one known reference axis. The patient positioning device communicates patient position information including or with reference to the at least one known reference axis. The communicated patient position information allows the user to position the patient and/or a surgical tool using the communicated patient position information.

  • Patent number: 9414926
    Abstract: Embodiments of the invention provide knee prostheses which more faithfully and closely replicate the function, anatomy and physiology of the normal human knee yielding a number of advantages. Among other things, such prostheses can provide an increased range of motion and function more normally particularly in extension, deep flexion and during normal gait. Knee prostheses according to various aspects of the invention recognize that during movement of the knee, particularly during flexion, the kinematics of the bones of the knee are a result of achieving equilibrium of the forces that cause motion of the knee. In addition, the shape of the articular surfaces acting in combination with forces imposed by various muscles, ligaments and tendons, determines the direction of the large contact forces.
