  • Patent number: 9889013
    Abstract: A variable angle blade augment including an augment section and a separate plate or blade segment. According to some embodiments, a first connector of the blade segment and a socket capture mechanism of the augment section provide a ball and socket type joint. Additionally, the socket capture mechanism may be structured to allow for linear displacement of the first connector relative to at least one axis of the socket capture mechanism. By allowing for at least pivotal and linear relative displacement of the augment section and the blade segment, the variable angle blade augment may improve the ability to optimally position a buttress augment against a prosthetic acetabular shell. Moreover, the variable angle blade augment may provide the ability to utilize components of an implantable medical device after stabilizing the components to a bone structure of a patient.

  • Patent number: 9867708
    Abstract: A prosthetic femoral component (10) for an orthopedic prosthesis has a canted patellar groove adapted for optimal patella/component interaction, with the component configured to have a medial or lateral cant depending upon the method of implantation. The femoral component defines a distal “component transverse plane,” which is a plane tangent to the distal-most points of the component condyles (12, 14). In a “mechanical” implantation, the component transverse plane is substantially normal to the mechanical femoral axis of the femur after the component has been implanted. Where the femoral component is configured to be “mechanically oriented” in this manner, the component has a medially canted patellar groove. On the other hand, an “anatomic” implantation is one in which, after the component has been implanted, the component transverse plane is substantially parallel to an “anatomic” transverse plane.

  • Patent number: 9861475
    Abstract: Devices, systems, and methods employ an implant that is sized and configured to attach to the annulus of a dysfunctional heart valve annulus. In use, the implant extends across the major axis of the annulus above and/or along the valve annulus. The implant reshapes the major axis dimension and/or other surrounding anatomic structures. The implant restores to the heart valve annulus and leaflets a more functional anatomic shape and tension. The more functional anatomic shape and tension are conducive to coaptation of the leaflets during systole, which, in turn, reduces regurgitation. The implant improves function to the valve, without surgically cinching, resecting, and/or fixing in position large portions of a dilated annulus, or without the surgical fixation of ring-like structures.

  • Patent number: 9861505
    Abstract: An endograft includes a main body having a wall separating interior and exterior surfaces and adapted to be inserted within the vessel. The main body is characterized by a single proximal opening and two distal openings and at least one aperture extending through the wall. At least one stent is secured to the main body that upon expansion pressure fits the main body into the vessel. An open tunnel is secured to the interior surface of the main body around the main body aperture and secured somewhere along the tunnel length to provide fluid communication between the interior and exterior surfaces of the main body through the aperture and with the vascular branch in proximity to the main body aperture. The insertion of a sleeve positioned partly within the tunnel and extending beyond the exterior surface of the main body into the vascular branch assures to the vascular branch.
