Patent number: 11969353Abstract: 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: GrantFiled: June 3, 2020Date of Patent: April 30, 2024Assignee: 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

Patent number: 10441297Abstract: Methods and systems for installing an implant in an intramedullary canal are discussed. In an example, an intramedullary sounder tool has a sounder head including a plurality of teeth extending proximally from a distal tip towards a shank extending from the sounder head, each tooth comprising a distal cutting edge, a middle scraping edge, and a proximal cutting edge. The sounder head can be advanced into the intramedullary canal until the scraping edge engages cortical bone. If the scraping edge does not engage cortical bone, sounder tools having successively larger diameters can be advanced into the intramedullary canal until a scraping edge does engage the cortical wall, thereby avoiding cutting and damaging of the cortical bone. At such point, the width of the intramedullary canal and the implant used therein can be determined using markings on the shank that indicate the diameter of the sounder head.Type: GrantFiled: April 20, 2016Date of Patent: October 15, 2019Assignee: Zimmer, Inc.Inventor: Terry W. Wagner

The handle assembly can include first and second handles pivotally connected to each other and configured to control movement of the first and second fingers. The crossbar assembly can be configured to maintain the first and second fingers substantially parallel to each other during movement of the first and second fingers. The assembly tool can be used for assembling a bearing assembly to an ulnar component of an elbow prosthesis.Type: GrantFiled: March 13, 2013Date of Patent: February 12, 2019Assignee: Zimmer, Inc.Inventor: Terry W.

Patent number: 10092418Abstract: A tooling system and method is disclosed for removing a head portion of a modular implant from a stem portion of the implant. The tooling system can include first and second tools configured to releasably mate together when the upper and lower tools are in an assembled position, and a holder configured to releasably secure the first and second tools in the assembled position. The first and second tools can be inserted between the head portion and an adaptor of the stem portion. When the first and second tools are rotated in opposite directions, the first tool can exert pressure on the head portion of the implant sufficient to release the head portion from locked engagement with the adaptor. The first and second tools can include mating features that disengage from each other as the tools are rotated in opposite directions.Type: GrantFiled: August 14, 2015Date of Patent: October 9, 2018Assignee: Zimmer, Inc.Inventor: Terry W.
