  • Patent number: 10864091
    Abstract: A prosthetic knee having a passive knee locking mechanism that uses the same four-bar mechanics found in a natural knee. The flexible four-bar mechanism guides the motion of the knee, aids in the return of the knee from full flexion to extension, and connects a femoral gear to a tibial gear. The gears have a circular radius and are connected using parallel links to keep the femur and tibia together when the knee is active. The knee stays locked throughout the stance phase. At toe off, no weight is applied on the prosthetic knee allowing the knee to flex. The flexible links are stretched, thereby increasing the stiffness in the springs, and at terminal swing phase, moments before heel strike, the flexible links in the four-bar mechanism snap back to the extended/locking position and lockout once the user applies his/her weight on the knee.

  • Patent number: 10842620
    Abstract: A method of implanting a prosthetic heart valve includes advancing a prosthetic heart valve to an implantation location within a patient's body, positioning the prosthetic heart valve within a native heart valve annulus, expanding a frame of the prosthetic heart valve from a first contracted configuration to a first expanded configuration, and then contracting the frame to a second contracted configuration. The prosthetic heart valve may be repositioned and then re-expanded from the second contracted configuration to a second expanded configuration. The prosthetic heart valve is preferably released from the delivery apparatus while in the second expanded configuration. Releasing the prosthetic heart valve from the delivery apparatus may result in radial expansion of a flange portion of the prosthetic heart valve.

  • Patent number: 10835380
    Abstract: According to one example, a posterior-stabilized femoral prosthesis for a knee arthroplasty. The femoral prosthesis can include medial and lateral condyles, a femoral cam and a recess. The medial and lateral condyles can be shaped to articulate with a tibial articular surface of a tibial bearing component through a range of motion, in which full extension corresponds to zero degrees flexion of a knee joint and positive flexion corresponds to greater than zero degrees flexion of the knee joint. In a sagittal plane, the medial and lateral condyles can define medial and lateral multi-radius curves, respectively. The medial multi-radius curve can have a single common radius swept through a first angular extent to define a single arc length that extends from between substantially ?20 degrees flexion to substantially 90 degrees flexion, inclusive.
