  • Patent number: 10238506
    Abstract: Systems and methods for providing deeper knee flexion capabilities. In some instances, such systems and methods include a knee prosthesis that includes a femoral component for replacing at least a portion of a distal end of a femur. In some cases, the femoral component has a posterior condyle that is configured to articulate against a tibial articular surface. In such cases, an articular surface at a proximal portion of the posterior condyle is sized and shaped to extend at least half of an antero-posterior distance between a most posterior portion of the posterior condyle and a plane that is a continuation of a distal one fourth to one third of a posterior cortex of a femoral shaft of the femur.

  • Patent number: 10179045
    Abstract: Systems and methods of delivering and deploying a stented prosthetic heart valve having a wrap that is automatically deployed to prevent or mitigate paravalvular leakage. In various embodiments, during transcatheter delivery of the stented prosthetic heart valve, the wrap is extends beyond a stent frame of the stented prosthetic heart valve so that the profile of the stented prosthetic heart valve is not increased during delivery. The disclosed embodiments are arranged and configured so that upon expansion of a stent frame of the stented prosthetic heart valve, a plurality of elongated members automatically pull the wrap distally into a deployed arrangement.

  • Patent number: 10173027
    Abstract: Methods of modifying the luminal profile of a body vessel are described. An example method comprises advancing a cannula out of the distal end of a catheter disposed within the lumen of a body vessel of an animal and toward a target site on the wall of the body vessel; passing contrast dye through the cannula toward the target site; simultaneously continuing the advancing and passing until the distal end of the cannula punctures the inner layer of the wall of the body vessel at the target site; and passing a bulking agent through the cannula and into a space between connective tissue layers surrounding the vessel wall at the target site. Medical devices, medical device assemblies, and kits are also described.

  • Patent number: 10172710
    Abstract: A dual member stent-valve for transcatheter delivery to a native heart valve needing replacement. A first component is attached to the native annulus upstream of the native leaflets maintaining native leaflet function, and is held to the native annulus by barbs that are activated by a torus balloon after the first component is fully expanded. The torus balloon can be implanted along with the support frame. A limiting cable restricts further expansion of the first component and holds a second component that contains the replacement leaflets.

  • Patent number: 10166107
    Abstract: A femoral stem for use in hip replacement surgery, specifically hip replacement surgery in dogs and similar animals but also inclusive to implants used in humans. More particularly, the invention is directed to a femoral stem that includes a lateral bolt or post that protrudes through the cortex or wall of bone opposite the neck of the femoral stem. The lateral bolt or post reduces the occurrence of subsidence in implanted femoral stems. The lateral bolt or post provides an anchor point on the cortex or wall of bone as opposed to relying solely on the compression of the femoral stem against the wall of the bony canal of the femur being implanted.
