  • Patent number: 9439769
    Abstract: A method of installing a prosthesis assembly includes installing a base component in a prepared glenoid vault, axially aligning a plurality of slots in one of a stretched glenoid bearing component and a base component with a plurality of ridges in the other of the glenoid bearing component and the base component, each of the plurality of slots having a maximum length which is greater than a maximum length of a respective one of the plurality of ridges, engaging each of the plurality of ridges with the respective one of the plurality of grooves thereby rotatably coupling the glenoid bearing component and the base component and limiting axial movement of the glenoid bearing component relative to the base component, and placing the bearing surface into articulating contact with a humeral head.

  • Patent number: 9194640
    Abstract: This technology relates to a one-piece sleeve which envelops a chamber with a baffle in a firearm suppressor body. The one-piece sleeve has an elongate opening, or slot, extending longitudinally along all, or part of, the length of the sleeve. The slot may be straight or curved. Also, there may be a plurality of slots. This way, because of the slot(s), the sleeve has increased flexibility and may be easily slightly opened up, and more easily removed from the elongate suppressor body for cleaning.

  • Patent number: 9107629
    Abstract: A method for retraction useable in joint arthroplasty. The method includes using a joint retractor having a first arm and a second arm. The first arm has a first portion and a second portion and the second arm having a first portion and a second portion. The retractor is inserted into a surgical opening of a patient's shoulder joint. The second portion of the first arm is placed against the coracoid process and the second portion of the second arm is placed against the resected humerus. The first portions of the first and second arms are hung over the resected tissue to allow exposure of the glenoid.
