Abstract
An intervertebral implant for supporting vertebrae that includes an anterior end element, a posterior end element, and four wings disposed between the anterior end element and the posterior end element. The four wings and the anterior and posterior end elements define a substantially open central space. The wings are arranged in pairs facing in opposed directions and include teeth facing in those opposed directions for gripping substantially planar surfaces at opposite sides of the implant.
Claims27
An intervertebral implant, comprising:
- an anterior end element having a cross-sectional area that increases in a direction from an anterior end of the implant toward a posterior end of the implant along a central axis of the implant;
- four wings extending from the anterior end element in the direction of the posterior end, generally parallel to the central axis, and defining a substantially open space;
- and
- a posterior end element at the posterior end connected with the four wings, wherein each of a first two of the four wings have a plurality of teeth configured to abut a first plane and each of a second two of the four wings have a plurality of teeth configured to abut a second plane parallel and spaced apart from the first plane, the first and second planes being parallel to a third plane containing the central axis of the implant;
- and
- four posterior support members connected between the posterior end element and each one of the four wings, each of the four posterior support members being arranged to act as a cantilevered spring;
- wherein the four wings are not connected with each other between the anterior and posterior end elements.

An intervertebral implant, comprising:
- an anterior end element at an anterior end of the intervertebral implant;
- a posterior end aligned with the anterior end element along a central axis of the intervertebral implant and separated from the anterior end element;
- a posterior end element at the posterior end of the intervertebral implant and
- four wings extending laterally between the anterior end element and the posterior end element, wherein:
- an outer surface of each of the four wings comprises a plurality of grooves and a plurality of teeth;
- the anterior end element, the posterior end element, and the four wings define a substantially open space therebetween;
- each wing of the four wings is connected by at least one respective structural element of a plurality of structural elements, each respective structural element of the plurality of structural elements being arranged to act as a cantilevered spring;
- and
- wherein the four wings are not connected with each other between the anterior and posterior end elements.
