  • Patent number: 10543096
    Abstract: A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores shock absorption, stability, and function to the knee joint after removal of the damaged natural meniscus. In some embodiments, the prosthetic device is pre-tensioned to improve the fit of the prosthetic device within the knee joint and, thereby, maximize the contact area of the load-bearing surfaces to distribute loading through the prosthetic device in a manner substantially similar to that of a healthy natural meniscus. In some embodiments, the pre-tensioned prosthetic device is smaller, or scaled-down, relative to the size of a healthy natural meniscus.

  • Publication number: 20140249627
    Abstract: Methods of selecting and implanting prosthetic devices for use as a replacement meniscus are disclosed. The selection methods include a pre-implantation selection method and a during-implantation selection method. The pre-implantation selection method includes a direct geometrical matching process, a correlation parameters-based matching process, and a finite element-based matching process. The implant identified by the pre-implantation selection method is then confirmed to be a suitable implant in the during-implantation selection method. In some instances, the during-implantation selection method includes monitoring loads and/or pressures applied to the prosthetic device and/or the adjacent anatomy. In some instances, the loads and/or pressures are monitored by a trial prosthetic device comprising one or more sensors. Methods of implanting meniscus prosthetic devices are also disclosed.

  • Patent number: 8814946
    Abstract: An acetabular implant for use in a hip joint prosthesis is disclosed. The implant includes a body portion comprising a polycarbonate polyurethane. The body portion includes a substantially semispherical inner articulating surface defining a socket sized to receive a head portion of a femoral component of the hip joint prosthesis and an outer engagement surface having an annular protrusion extending outwardly therefrom. The annular protrusion is configured for snap-fit engagement with a corresponding recess in the acetabulum. The implant also includes a deformation control element having an increased durometer hardness relative to the polycarbonate polyurethane and positioned within the body portion between the inner articulating surface and the outer engagement surface.

  • Patent number: 8361147
    Abstract: A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores shock absorption, stability, and function to the knee joint after removal of the damaged natural meniscus. In some embodiments, the prosthetic device includes an anti-migration feature. The anti-migration feature is a bridge for engagement with a femur notch in some instances. Generally, the anti-migration feature allows the artificial meniscus to be implanted into the patient's knee and maintain its position within the knee without penetrating the adjacent bone. The bridge is reinforced with fibers in some instances.

  • Publication number: 20110190901
    Abstract: Devices, apparatus, and systems for replacing at least some of the functionality of the natural hip joint and associated methods of implantation are disclosed. In one aspect a prosthetic acetabular cup system is provided. The system includes a metal shell comprising an outer surface for securely engaging a prepared portion of an acetabulum and an opposing inner surface. In some instances, portions of the inner and outer surfaces define an anchoring section that is deformable between an insertion configuration—where the anchoring section projects inwardly from the inner surface—and an anchoring configuration—where the anchoring section projects outwardly from the outer surface to define an anchoring protrusion for engaging the prepared portion of the acetabulum. In some embodiments, the system also includes a pliable articulating component having an outer surface including at least one engagement feature sized and shaped to engage with the metal shell.

  • Patent number: 7780740
    Abstract: A method of implanting a prosthetic acetabular cup into a patient is disclosed. The method comprises gaining access to an acetabulum of the patient, where the acetabulum includes an inner portion formed of bone and an outer portion formed of articular cartilage. The method also comprises creating a recess within the articular cartilage of the outer portion of the acetabulum without removing any portion of bone from the inner portion of the acetabulum. The recess is shaped to mate with a snap-fit structure of the prosthetic acetabular cup. Finally, the method comprises securely engaging the prosthetic acetabular cup with the acetabulum by snap-fitting the snap-fit structure of the prosthetic acetabular cup with the recess in the articular cartilage of the outer portion of the acetabulum.
