Patent number: 11911292Abstract: Disclosed herein are systems and methods for intervertebral body fusion that provide more robust support within the disc space. Intervertebral body fusion devices can have a unitary monolithic body including a plurality of body segments interconnected with each other by flexure members. Devices be configured to be inserted through an opening in a compressed configuration and then expanded within the disc space to an expanded configuration. In the expanded configuration, devices can have a greater mediolateral or transverse to the disc space footprint. This wider footprint provides greater support for the vertebrae relative to the size of the opening through which the device is inserted.Type: GrantFiled: February 1, 2022Date of Patent: February 27, 2024Assignee: Octagon Spine LLCInventors: Omar F. Jimenez, Yefim I. Safris

Publication number: 20230104776Abstract: An expandable intervertebral cage device includes a first base plate and a second base plate, a distal block with an internal passage that mechanically couples to each base plate, and a proximal block comprising internal threading. The device has exactly two arm assemblies with one on each side. Each arm assembly comprises a first arm mechanically coupled to the first base plate and a second arm mechanically coupled to the second base plate. A screw is arranged partially within the internal threading of the proximal block and passes through the internal passage of the distal block, such that rotation of the screw relative to the distal block causes a change in distance between the distal block and the proximal block, and a corresponding change in the spacing and lordosis of the device.Type: ApplicationFiled: September 28, 2022Publication date: April 6, 2023Inventors: Omar F.

Patent number: 9498270Abstract: An inserter can be used to implant a distractible intervertebral body fusion device into a disc space and expand the device. The inserter includes a shaft frame and a drive shaft assembly for expanding the device and a support shaft assembly for stabilizing the device extending distally from the shaft frame. A drive housing can be operably connected to the shaft frame and extend outwardly from shaft frame distal of a proximal end of the shaft frame. Drive housing can have an internal passage that provides access into the shaft frame to a proximal end of the drive shaft assembly. An actuation tool can be disposed with the drive housing with a distal end extending through the access into the shaft frame to interface with the proximal end of the drive shaft assembly such that activation of the actuation tool rotates the drive shaft assembly to expand the device.Type: GrantFiled: January 8, 2015Date of Patent: November 22, 2016Assignee: SpineX Tee, LLCInventors: Omar F.

Patent number: 8636746Abstract: An introducer can be used to implant a distractible intervertebral body fusion device into a patient's disc space and expand the device. Introducer includes a body 100 including a handle and a sleeve. Handle includes a slot for containing an actuation tool. A drive shaft and a securing shaft can extend through sleeve between a proximal end of the sleeve adjacent slot and a distal end of the device. At proximal end, actuation tool can connect to drive shaft where drive shaft extends through an opening in body. Drive shaft can extend out of an opening at distal end to engage a worm gear, drive shaft, or other actuation member of distractible device. Securing shaft can engage the device to stabilize the device during distraction. Activation of the actuation member rotates the drive shaft, which expands the distractible device.Type: GrantFiled: July 22, 2011Date of Patent: January 28, 2014Assignee: Spinex Tec, LLCInventors: Omar F.
