Patent number: 8986384Abstract: A method of stabilizing a portion of a spine includes pivoting first and second members of an expandable spinal implant relative to one another to a closed configuration in which the spinal implant has a compact profile, inserting the spinal implant in the closed configuration into the spine between first and second vertebral bodies, and pivoting and locking the first and second members crosswise to an expanded configuration while the spinal implant is within the spine. The first and second members are separate from and coupled to one another.Type: GrantFiled: January 28, 2013Date of Patent: March 24, 2015Assignee: ResSpond Spinal SystemsInventors: Marc I.

Publication number: 20090192549Abstract: A bone plating system has a plate and a locking element. The plate has a bone screw aperture defined by a sidewall including first and second substantially planar segments. The locking element is coupled to the plate and at least partially positioned in the aperture. The locking element has an external geometry defining first and second substantially planar surfaces and an internal geometry for receiving a head of a bone fastener and preventing the bone fastener from backing out of the plate. The locking element is expandable from a first state to a second state. In the first state the locking element is permitted to articulate relative to the plate. In the second state the first and second substantially planar surfaces of the locking element engage the first and second substantially planar segments of the aperture sidewall, respectively, to prevent relative movement between the locking element and the plate.Type: ApplicationFiled: January 29, 2009Publication date: July 30, 2009Applicant: EBI, LLCInventors: Laurie SANDERS, Gretchen DOUGHERTY SHAH, Rui J.

The first and second bone engagement surfaces can define an outer surface substantially shaped as an envelope of two intersecting cylinders. In one aspect, the first and second articulating surfaces can have substantially equal radii of curvature in a coronal plane and different radii of curvature in a sagittal plane.Type: ApplicationFiled: June 4, 2008Publication date: January 15, 2009Applicant: EBI, LLCInventors: Stephen D.

Patent number: 7470273Abstract: A tool for inserting or removing an intervertebral implant. The tool includes a first arm having a curved tip adapted for engaging a side wall groove of the intervertebral implant and a second arm pivotably coupled to the first arm. The first arm defines a first concave distal surface extending continuously from the curved tip and the second arm defines a second concave distal surface. The first and second concave distal surfaces define an engagement surface engageable to a substantially complementary convex end wall of the intervertebral implant.Type: GrantFiled: June 25, 2004Date of Patent: December 30, 2008Assignee: EBI, LLCInventor: Gretchen Dougherty-Shah

Patent number: 7465317Abstract: An expandable spinal implant including a first member and a second member. The first member has first and second arms. The first and second members are pivotally coupled to each other for relative movement about a rotation axis between a closed position for inserting the implant into a spine and an expanded position for providing structural support to the spine. The expandable implant includes a locking mechanism for arresting relative movement between the first member and the second member.Type: GrantFiled: April 6, 2007Date of Patent: December 16, 2008Assignee: EBI, LLCInventors: Marc I. Malberg, Gretchen Dougherty Shah, Rui J. Ferreira

Patent number: 7318839Abstract: An expandable spinal implant including a first member and a second member. The first member has first and second arms. The first and second arms of the first member both including an upper face partially defining an upper contact area of the implant and a lower face partially defining a lower contact surface of the implant. The second member has first and second arms that both include an upper face partially defining an upper contact area of the implant and a lower face partially defining a lower contact surface of the implant. The first and second members are pivotally coupled to each other for relative movement about a rotation axis between a closed position for inserting the implant into a spine and an expanded position for providing structural support to the spine. The rotation axis extends generally perpendicular to the upper and lower contact surfaces.Type: GrantFiled: July 22, 2004Date of Patent: January 15, 2008Assignee: EBI, L.P.Inventors: Marc I Malberg, Gretchen Dougherty Shah, Rui J Ferreira
