Patent number: 11963887Abstract: An adjustment tool configured to adjust an intervertebral implant comprises a housing, a traveler member, a tether member, and a drive member. The traveler member is coupled to the housing. A proximal end of the tether member is coupled to the traveler, and a distal end of the tether member is configured to couple to the implant. The tether member is substantially linearly fixed to the traveler and rotatable relative to the traveler. The drive member is configured to transition between 1.) a first position in which the drive member is coupled to the tether such that rotation of the drive member causes rotation of the tether relative to the traveler, and 2.) a second position in which the drive member is coupled to the traveler such that rotation of the drive member causes rotation of the traveler relative to the housing.Type: GrantFiled: July 6, 2020Date of Patent: April 23, 2024Inventors: Alec Manson, Sean Saidha, Connor Engstrom

Publication number: 20230372119Abstract: The present disclosure relates to a spinal implant. The spinal implant may be used for lateral insertion into an intervertebral disc space. For example, the spinal implant may include a spacer body to which a plate is fixed. The intervertebral spacer body may include a pair of opposite sides having a pyramid-shaped teeth to fuse to bone. The plate defines at least one upper and lower borehole that each receives a screw. Each screw attaches the plate to a vertebral body between which the intervertebral spacer body is inserted. The boreholes may include locking threads that are adapted to lock the screws into place by engaging complementary locking threads of head of the screw.Type: ApplicationFiled: May 23, 2023Publication date: November 23, 2023Inventors: Lawton Laurence, Sean Saidha, Michael White, Khawar Mohammad Siddique, Brian Regis Perri

Publication number: 20230277329Abstract: An expandable intervertebral cage includes vertically opposed superior and inferior plates and longitudinally opposed distal and proximal wedges disposed between the plates. The wedges define ramps that engage complimentary ramps of the superior and inferior plates to increase a vertical distance between the plates. An actuator is located between the plates, defines a central, longitudinal axis, and is coupled to the wedges such that, as the actuator rotates about the axis, at least one of the wedges moves longitudinally relative to the other, thereby increasing the vertical separation distance. At least one locking component is insertable within a receptacle at least partially defined by the proximal wedge and is configured to transition from an unlocked configuration, where the actuator is rotatable relative to the proximal wedge, to a locked configuration, where the actuator is rotationally affixed relative to the proximal wedge.Type: ApplicationFiled: March 1, 2022Publication date: September 7, 2023Inventors: Meredith Walsh, Phat Luu, Roger Berger, Connor Engstrom, Didier Gonzalez, Stephane Gully, Markus Hunziker, Thomas Martin, Jonathan Melchor, Sean Saidha
