Patent number: 11931084Abstract: An orthopedic fixation system includes an orthopedic implant and an implant retainer. The orthopedic implant includes a transition section deformable to move the orthopedic implant between a natural shape and an insertion shape whereby a transition of the orthopedic implant from the natural shape to the insertion shape stores deliverable energy and a transition of the orthopedic implant from the insertion shape to the natural shape delivers stored energy. The implant retainer is configured to mechanically engage the orthopedic implant across the transition section such the implant retainer constrains the orthopedic implant in the insertion shape thereby preventing a transition of the orthopedic implant from the insertion shape to the natural shape.Type: GrantFiled: December 7, 2021Date of Patent: March 19, 2024Assignee: DePuy Synthes Products, Inc.Inventors: Adam T. Knight, Daniel F. Cheney, Lisa P. Actis, Donald W. Petersen
