Patent number: 11464554Abstract: The present invention includes devices, systems and methods for the storage, retrieval and placement of plates having wedges. A wedge plate tray includes an upper portion and at least one recessed portion, the recessed portion including a cavity sized to house the wedge and an additional cavity sized to accommodate placement and movement of an arm of an insertion instrument. The insertion instrument includes two arms connected at a hinge, a tip of each arm including a mating connector sized to engage a complementary mating connector on the wedge. In one embodiment of the method, the insertion instrument can be used to place the wedge plate in an osteotomy and where the wedge is a mobile wedge, a plate component can be adjusted to a desired position for securement while using the insertion instrument to hold the wedge in place in the osteotomy.Type: GrantFiled: March 24, 2020Date of Patent: October 11, 2022Assignee: Stryker European Operations Holdings LLCInventors: Martin Felder, Marcel Abt, Oliver Ammann
