  • Shoulder prosthesis
    Patent number: 9301847
    Abstract: A humeral prosthesis includes a stem component and a head component joined by an inclination component. The inclination component is provided with an opening that is designed to accommodate a pair of expandable tabs extending from a side of a plate. The plate is also provided with a taper extending opposite to the pair of expandable tabs. Inclination angle, radial offset, and version are adjustable and are separately and independently set and fixed.
    Type: Grant

  • Expanding plug for tendon fixation
    Patent number: 7785357
    Abstract: An expanding plug for tendon fixation features a two-part system in which an expansion pin fits inside a fixation sleeve. The fixation sleeve is configured to expand diametrically to achieve interference fixation of a graft tendon inside of a bone tunnel. Fixation sleeve expansion is urged by a two-step engagement of the expansion pin. The tendon graft is assembled to the expanding bolt and situated within a bone tunnel. Passing suture is used to pull a joint-line end of the expansion pin into the tunnel to partially expand the fixation sleeve at the joint-line end. Pulling a graft end of the expansion pin toward the joint line expands the fixation sleeve to place the expanding plug in the fully deployed configuration.
