Patent number: 8932302Abstract: 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: October 26, 2012Date of Patent: January 13, 2015Assignee: SpineX Tec, LLCInventors: Omar F.

Publication number: 20140140757Abstract: Improved flexible joint arrangements employ at least one flexure member that interfaces with wrapping surfaces defined on the bases to which the ends of the flexure member are connected. The flexure members are configured to define a traveling instantaneous axis of rotation that moves along a path defined by the interface of the flexure and the wrapping surfaces as the bases move relative to each other. The flexure members and the bases can be constructed of a monolithic material. The wrapping surfaces of the bases can be asymmetric in cross-sectional shape. The radius of curvature of the traveling instantaneous axis of rotation can be configured to change only in discrete quantum steps without reversals. In other embodiments, the flexible joint arrangement can be configured as one or more three bar linkages in which the middle bar is rigid and the outer bars are flexure members in accordance with the various embodiments.Type: ApplicationFiled: September 12, 2013Publication date: May 22, 2014Applicant: SPINEX TEC, 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.

Patent number: 8523944Abstract: Improved methods and apparatuses for vertebral body distraction and fusion in accordance with various embodiments of the present invention employ flexure members. Flexure members connect a plurality of structural members to end plates on one end and blocks on another end. Upon insertion into the disc space, a drive screw or similar mechanism can be actuated to drive expansion blocks closer together, which causes flexure members to deflect, resulting in expansion of the structural members and distraction of the end plates. The distracted device can then remain in the body and be used for vertebral body fusion.Type: GrantFiled: December 31, 2009Date of Patent: September 3, 2013Assignee: SpineX Tec, LLCInventors: Omar F.
