  • Patent number: 11911279
    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.

  • Patent number: 11883110
    Abstract: The subject matter includes a system and method for providing graphical feedback visualizing forces within a joint through a range of motion of the joint. The method can comprise receiving position data, receiving force data, and generating a graphical representation based on the position data and the force data. The receiving position data can include data for at least one bone of a joint while the at least one bone is moved through a range of motion (ROM). The receiving force data can occur concurrently to receiving the position data and using one or more processors, the force data can be collected from at least one force sensor embedded within a trial prosthesis in the joint. The graphical representation can illustrate changes in the force data versus locations of the bone as it moved through the ROM.

  • Patent number: 11826256
    Abstract: A system can form a pilot hole to secure a securable element, such as an acetabular cup. A saddle can removably attach to the securable element. The saddle can confine a translator and allow the translator to move along a translator axis between a first translator position and a second translator position. A punch element can be movably coupled to the saddle and the translator such that when the saddle is removably attached to the securable element, moving the translator from the first translator position toward the second translator position can advance a tip of the punch element from the saddle through the securable element along a punch axis that is angled with respect to the translator axis. An impaction stem can be coupled to the translator by a joint, such as a ball-and-socket joint, and can impart motion to the translator.

  • Patent number: 11759795
    Abstract: A blood washing system (20) having a rotor (22) defining an internal chamber for receiving a multi-component fluid and a skimmer assembly (24) including a moveable buoy (28) having an orifice (32) fluidly connected to an access port for the rotor for selectively withdrawing separated fractions of the multi-component fluid. The multi-component fluid can be fed into the internal chamber before the rotor (22) can be rotated at a first speed to fractionate the multi-component fluid. A brake can be applied to the rotor to slow rotation of the rotor to a slower second speed or stop rotation of the rotor causing the solid and denser fluid fractions to settle on the bottom wall (44) of the rotor (22). The buoy (28) can have a specific gravity corresponding to a selected fraction such that the buoy floats on a surface of the selected fraction, wherein the fractions floating on the selected fraction can be withdrawn through the orifice (32).
