Patent number: 9795487Abstract: Systems and methods for providing deeper knee flexion capabilities, more physiologic load bearing, and improved patellar tracking for knee prosthesis patients. 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. While the femoral component can include any feature, in some cases, it includes a condylar surface configured to articulate with an articular surface of a tibia. In some cases, the femoral component also includes a proximal extension that extends from a proximal, posterior portion of the condylar surface. In such cases, the proximal extension provides the femoral component with a concave articulation surface that is configured to articulate against a portion of the tibia. Other implementations are also described.Type: GrantFiled: September 24, 2012Date of Patent: October 24, 2017Inventors: Kent M. Samuelson, Conner E. Samuelson

Patent number: 9795488Abstract: A prosthetic device for use as an artificial meniscus is disclosed. The prosthetic device restores stress distribution, 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 that inhibits extreme movement within the joint while permitting free floating over a significant range. In one aspect, the anti-migration feature is an enlarged anterior structure or a posterior meniscus remnant engaging channel while in another aspect, the anti-migration feature includes a tethering member. Still further, removable radiopaque features are provided to enhance trialing of the implant prior to final implantation within the joint.Type: GrantFiled: April 21, 2016Date of Patent: October 24, 2017Assignee: Active Implants LLCInventors: Eran Linder-Ganz, Lex R. Giltaij, Richard W. Treharne, Thomas B. Buford, Dvora Galli

Patent number: 9795490Abstract: A glenosphere includes a body, a first surface, a second surface, a cavity defined within the body, and a plurality of channels. The body defines a central axis passing through the body. The first surface includes a first rim and a second rim. The first rim is positioned radially outward from the second rim relative to the central axis. The second surface extends from the first rim of the first surface. The second surface has a convex shape. The cavity has a perimeter defined by the second rim and is configured to receive an attachment structure attachable to a bone. The plurality of channels extend from the first surface through the body to the second surface. Each channel defines a first opening positioned on the first surface between the first rim and the second rim and defines a second opening positioned on the second surface. Each channel is configured to receive a bone fixation member configured to secure the glenosphere to the bone.Type: GrantFiled: July 15, 2016Date of Patent: October 24, 2017Assignee: DJO GLOBAL, INC.Inventors: Mark A. Frankle, Sergio Gutierrez, Gerald Williams
