  • Patent number: 10932979
    Abstract: Provide is a health appliance and a method using the same which achieve active and appropriate assistance of bending of a knee joint. The health appliance, which allows a user lying or seated to move their knee joint while supporting the knee joint, includes a support 1 which is a triangular prism having one side surfaces as a bottom surface 11, and an aid 2 mounted on the leg below the knee and can be pulled by the user. The support 1 has a width W at which one knee is supported, and has a cross section forming a triangle with a base corresponding to one side surface 11 and an acute diagonal angle ?1. When sandwiched under the user's knee, the base angle ?2 adjacent to the toe is larger than the diagonal angle ?1 and smaller than the base angle ?3 adjacent to the thigh.

  • Patent number: 10932927
    Abstract: Stents generally can include multiple longitudinal elements each extending over a majority of the length of the stent and each having alternating flexible and rigid segments. The stents can include nodes positioned between the flexible and rigid segments on the longitudinal elements and interconnecting members extending circumferentially to connect adjacent longitudinal elements at the nodes. The longitudinal elements can have a wave pattern and the interconnecting members can have a branch structure connecting peaks from one longitudinal element to troughs of an adjacent longitudinal element. The resulting stent structure can have lateral and longitudinal flexibility needed to navigate and conform to intracranial arteries with the benefits of recapturability and structural integrity of a closed cell design.

  • Patent number: 10842623
    Abstract: An exemplary two-stage prosthetic heart valve system has a radially expandable base stent implanted within a native valve annulus. The base stent desirably has three position markers projecting in the axial direction from the outflow end of the base stent to assist in aligning the stent with respect to the commissures of the native valve. The two-stage heart valve system also has a valve component that is delivered to and mounted within the base stent in a separate or sequential operation after the base stent has been anchored within the annulus. The valve component in certain embodiments comprises a hybrid valve component that includes a conventional, non-expandable surgical valve that is modified to include an expandable coupling stent that can be expanded to engage the inner surface of the base stent, thereby anchoring the valve component to the base stent.
