  • Publication number: 20200046512
    Abstract: A spinal interbody device (IBD) includes a solid wall that at least partially defines a boundary of the IBD and a porous body connected to the solid wall. The porous body includes a plurality of sections that form at least a portion of both a superior and inferior bone interface side of the IBD. Each section of the porous body has a different porosity than an adjacent section such that the porosities increase toward a center of the IBD.

  • Patent number: 10537666
    Abstract: Implants including non-resorbable frameworks and resorbable components, as well as methods of use thereof are disclosed. The embodiments include different combinations of a non-resorbable framework (in some case structural and in other cases non-structural), and a resorbable component embedded within and/or around the framework (again, in some cases structural and in other cases non-structural). The disclosed implants provide an efficient means of providing structural support for the vertebral bodies post-implantation, as well as encouraging resorption of the implant and fusion of the associated vertebral bodies without negative side effects and/or failure, such as subsidence of the implant or cracking/fracturing of a portion of the implant when implanted.

  • Patent number: 10485675
    Abstract: An intervertebral implant may include an input for expanding at least two extendable support elements connected to a body at respective locations, such that the extendable support elements each apply a respective expansion force directed away from a surface of the body. Application of a single input force to the input may induce the extendable support elements to apply different amounts of expansion force. Alternatively or additionally, an intervertebral implant may include at least two portions connected together by a hinge for articulation about the hinge. In one aspect, the hinge may include at least two rigid links each pivotably connected to the two portions. In another aspect, a rigid link of the hinge may include a passageway for communicating a hydraulic fluid between the two portions. A locking system may be positionable into successive locked configurations by operation of a cam to prevent contraction of an extendable support element.

  • Patent number: 10470891
    Abstract: Expandable spinal interbody implants include a body and at least one extendable support element connected thereto. Such an implant may include a second extendable support element and a tool selectively positionable with respect to the implant so as to independently or simultaneously expand both extendable support elements. In another example, such an implant may include, at each of a first and second location, a respective movable member and a respective locking element. The at least one extendable support element may be actuatable to expand so as to induce movement of at least one of the movable members away from the body. The locking elements at each of the first and second locations may be selectively lockable such that, when locked, the locking element restrains movement of the associated movable member at that location away from the body without restraining movement of the other movable member away from the body.

  • Publication number: 20190328425
    Abstract: An expandable rod system includes a first rod portion having an internal cavity, a second rod portion sealingly positioned within the internal cavity of the first rod portion and moveable in a first axial direction relative to the first rod portion, and an osmotic chamber for receiving an osmotic agent to facilitate movement of the second rod portion to expand the rod system. The rod system includes a lock assembly engageable with the second rod portion to prevent the second rod portion from moving in a second axial direction. The lock assembly includes a tapered ramped portion and a bearing member that is moveable within the tapered ramped portion such that when compression forces are imparted on the second rod portion, the bearing member becomes wedged in the tapered ramped portion.

  • Publication number: 20190175360
    Abstract: A device for loading bone graft material into a delivery tube is provided herein. The device includes a housing defining a reservoir for receiving bone graft, a magazine at least partially disposed within the housing, and an actuation member coupled to the housing for discharging the bone graft material into the delivery tube. The magazine defines a first chamber and a second chamber and is moveable between a first position in which the first chamber is in communication with the reservoir and a second position in which the second chamber is in communication with the reservoir. The actuation member includes a plunger configured to slide into the first chamber and the second chamber to discharge bone graft material, when bone graft material is contained therein, into the delivery tube. Methods of loading bone graft material are also provided.

  • Publication number: 20190083283
    Abstract: A system for implanting an expandable interbody implant into an intervertebral space includes an elongated tool, the distal end of which is removably securable to the implant. The proximal end of the tool has an attachment interface for detachable securement to a plurality of different modules, each of which is adapted to effectuate a different function of the delivery system. The different functions include: grasping the implant delivery tool, providing an impaction surface for driving the advancement of the implant, supplying a graft material into the implant, and actuating the expansion of the implant. One of the modules may include a fluid delivery system for supplying hydraulic fluid to expand the implant. A fluid reservoir of the fluid delivery system may be oriented transverse to the cannula that delivers the fluid to the implant. A grafting block can be used to help pre-pack the implant with graft material.

  • Publication number: 20170333199
    Abstract: A spinal implant for placement between vertebral bodies includes a first member for engaging one of the vertebral bodies, a second member for engaging an opposing one of the vertebral bodies, and at least one extendable support element for inducing movement of the entire first member away from the second member. The first member is connected to the second member such that the first member moves away from the second member by a larger distance at a first end of the implant than at a second end of the implant. A connecting member may connect the first and second members together at the second end of the implant. The connecting member may include one or more rotatable linkages, or the connecting member may be an extension of one of the first and second members slidably received within a track defined within the other of the first and second members.

  • Publication number: 20140277203
    Abstract: A drive train includes a torque multiplier assembly and a torque limiter device. An output of the torque multiplying assembly is drivingly coupled to an input of the torque limiter device. An input of the drive train is configured to be driven by a driver handle and an output of the drive train is configured to rotate a driver. A counter-torque connector that is configured to engage a spinal fixation construct is coupled to a counter-torque handle to prevent rotation of the spinal fixation construct. A coupling between a component of the torque multiplier assembly and the counter-torque handle prevents rotation of the component. Torque input by the single user through the driving handle is simultaneously multiplied by the torque multiplier assembly and limited by the torque limiter device, while the single user simultaneously prevents the spinal fixation construct from rotating through the counter-torque handle.
