Publication number: 20210338455Abstract: 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.Type: ApplicationFiled: July 12, 2021Publication date: November 4, 2021Inventors: Amir Ali Sharifi-Mehr, Oliver Buchert, M.

Publication number: 20210315712Abstract: 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.Type: ApplicationFiled: June 25, 2021Publication date: October 14, 2021Inventors: Amir Ali Sharifi-Mehr, Oliver Buchert, Ronald Litke, Thomas A.

Patent number: 11058547Abstract: 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.Type: GrantFiled: October 4, 2019Date of Patent: July 13, 2021Assignee: Howmedica Osteonics Corp.Inventors: Amir Ali Sharifi-Mehr, Oliver Buchert

Publication number: 20210145600Abstract: 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.Type: ApplicationFiled: January 26, 2021Publication date: May 20, 2021Inventors: Amir Ali Sharifi-Mehr, Oliver Buchert
