Patent number: 11622864Abstract: An expandable intervertebral implant includes a superior plate having a proximal end, an opposing distal end, and a threaded first hole. An inferior plate has a proximal end, an opposing distal end, and a first bore, the inferior plate at least partially bounding an elongated channel that communicates with the first bore. A first lift screw includes a gear wheel rotatably received within the first bore of the inferior plate and a threaded stem projecting from the gear wheel and being threaded into the first hole of the superior plate. A drive screw is rotatably disposed within the channel of the inferior plate, the drive screw having a worm that engages with the gear wheel such that rotation of the drive screw facilitates rotation of the first lift screw which in turn facilitates movement of the superior plate relative to the inferior plate.Type: GrantFiled: June 25, 2020Date of Patent: April 11, 2023Assignee: Innovasis, Inc.Inventors: Daniel E. Gerbec, James Robbins, Eric Wieser, Ronald K. Groberg, Brent A. Felix

Patent number: 8834529Abstract: A method for mounting a polyaxial screw into a bone includes rotating a drive cap so that a screw mounted to the drive cap is screwed into a bone, the drive cap having a socket in which a portion of the screw is pivotably disposed, at least a portion of a collet being disposed within the socket between the screw and the drive cap. A stabilizing structure and a fastener are positioned onto a shaft projecting from the drive cap. The fastener is advanced along the shaft so as to push a portion of a compression cap against the collet which in turn wedges the collet within the socket of the drive cap and causes the collet to bias against a portion of the screw, thereby locking the position of the screw, the collet, and the drive cap relative to each other.Type: GrantFiled: December 13, 2011Date of Patent: September 16, 2014Assignee: Innovasis, Inc.Inventors: Brent A.
