Abstract
An expandable spinal interbody implant is provided that includes first/second components that are movable between collapsed and expanded states. Spaced apart surfaces with defined radii are associated with one of the components and cooperate with slots defined in the other of the components. A locking mechanism, e.g., a locking screw, may secure the components in a desired relative orientation.
Claims10
An expandable interbody implant, comprising:
- a. a first component defining an upper surface;
- b. a second component movable relative to the first component between a collapsed state and an expanded state,
- wherein the first component includes at least one upwardly extending sheet that projects from the upper surface;
- wherein the second component defines at least one mating slot configured and dimensioned to receive the at least one upwardly extending sheet of the first component;
- wherein the at least one upwardly extending sheet is radiused relative to the upper surface and wherein the at least one mating slot defines an internal radius;
- and
- wherein the radius of the at least one upwardly extending sheet and internal radius of the at least one mating slot are selected to permit relative movement between the first component and the second component when the at least one upwardly extending sheet travels relative to the at least one mating slot.

A method for moving an expandable interbody implant from a collapsed orientation to an expanded orientation, comprising:
- a. providing an expandable interbody implant that includes:
- i. a first component defining an upper surface;
- and
- ii. a second component movable relative to the first component between a collapsed state and an expanded state,
- wherein the first component includes at least one upwardly extending sheet that projects from the upper surface;
- wherein the second component defines at least one mating slot configured and dimensioned to receive the at least one upwardly extending sheet of the first component;
- wherein the at least one upwardly extending sheet is radiused relative to the upper surface and wherein the at least one mating slot defines an internal radius;
- and
- wherein the radius of the at least one upwardly extending sheet and internal radius of the at least one mating slot are selected to permit relative movement between the first component and the second component when the at least one upwardly extending sheet travels relative to the at least one mating slot;
- and
- b. moving the first component relative to the second component between a collapsed state corresponding to a collapsed orientation and an expanded state corresponding to an expanded orientation.
