  • Patent number: 11969353
    Abstract: The present disclosure relates to prosthesis systems having trays and liners having an asymmetrical locking mechanism to bias the strength of the liner to resist loading forces and associated methods. The tray has a lateral groove disposed in an inner surface of a lateral circumferential portion of the tray and a medial groove disposed in an inner surface of a medial circumferential portion of the tray. The liner has an upper segment and a lower segment. The liner has a locking portion for lockingly engaging the tray that includes the lower segment. The locking portion has a lateral toe positioned generally diametrically opposite a plurality of resiliently deformable medial fingers defined therein. The liner and the tray are engageable in a lateral-to-medial direction so that the plurality of medial fingers can resiliently deform to engage the medial groove subsequent to engagement of the lateral toe within the lateral groove.
    Type: Grant
    Filed: June 3, 2020
    Date of Patent: April 30, 2024
    Assignee: Zimmer, Inc.
    Inventors: Steven Humphrey, James D. Wernle, Joanna Surma, Stephen H. Hoag, Donald W. Dye, Kenton A. Walz, Terry W. Wagner, Kathleen Macke, Duane Gillard, Brian D. Byrd, Ken Yamaguchi
