Patent number: 9962270Abstract: An expandable implant is disclosed in which the implant includes top and bottom plates having angled inner surfaces that interact with expansion members. The expansion members may be situated on an actuator, and may include at least one vertical projection. In some instances, rotation of the actuator in opposing directions about a longitudinal axis may cause the expansion members to move toward or away from one another, thereby resulting in separation of the top and bottom plates. During such expansion of the implant, the at least one vertical projection of the expansion members may be guided at least partially within a recess formed in the first or second plate. Pins may also be included with the expansion members that ride along respective slots in the plates during expansion. An insertion instrument for implanting the aforementioned implant, and methods of using the same, are also disclosed.Type: GrantFiled: April 5, 2016Date of Patent: May 8, 2018Assignee: Stryker European Holdings I, LLCInventors: Thomas A.

Patent number: 9936977Abstract: A revisable orthopedic anchor and method of use for removably securing an anchor in bone, such as compromised or degenerated bone, is described herein. In one embodiment, the anchor makes use of dual probes and vector divergence of the distal tips of the probes to achieve superior bone purchase and pull-out resistance. In such an embodiment, the probes can be inserted one at a time into a hole formed in, for example, the pedicle bone. After the probes are inserted and joined at the proximal end, they have a greater pull-out resistance than a threaded anchor. Removing the anchor involves separating the proximal heads and reversing the implantation process. As a result of the unique bone anchor design disclosed herein, the devices and methods of the present invention allow for less complicated implantation and removal of orthopedic anchors, all while providing enhanced bone purchase when implanted in a patient.Type: GrantFiled: September 18, 2015Date of Patent: April 10, 2018Assignee: DePuy Synthes Products, Inc.Inventors: John Riley Hawkins, Alexander Grinberg, Michael Michielli
