Abstract
Disclosed herein are embodiments of a spinal implant having structures that incorporate a solid material and a porous material. The solid material provides the implant with an outer shell for structural integrity while the porous material, distributed within an interior of the implant as a lattice structure for example, promotes visibility of the implant in radiological imaging, promotes bony ingrowth and cell attachment and improves wicking.
Claims24
A spinal interbody implant comprising:
- a body comprising:
- a peripheral layer at least partially enclosing the body, the peripheral layer including a plurality of struts extending between an upper plate and a lower plate;
- and
- an inner region within the peripheral layer, the inner region defined by a plurality of interconnected tubes,
- wherein the plurality of interconnected tubes includes two or more interconnected tubes in a first layer, the two or more interconnected tubes extending transverse to the plurality of struts, the upper plate and the lower plate, and
- wherein at least one tube of the interconnected tubes includes an outer tubular part and an inner fill part disposed within a hollow interior of the outer tubular part, the outer tubular part being a first material with a first porosity and the inner fill part being a second material with a second porosity greater than the first porosity.

A spinal interbody implant comprising:
- a plurality of layers, each layer being a patterned lattice structure and interconnected with at least one other layer of the plurality of layers, the plurality of layers each comprising:
- a first layer having a structure including a first plurality of struts oriented in a first direction and a second plurality of struts oriented in a second direction, at least one strut of the first plurality of struts crossing at least one strut of the second plurality of struts such that the struts are interconnected, wherein a first strut of the first plurality of struts has a length and has a first porosity at a first crossing with a second strut of the second plurality of struts and a second porosity at a second crossing with a third strut of the second plurality of struts, the second strut being adjacent to the third strut, and wherein the first porosity is different from the second porosity.
(canceled)
The spinal interbody implant of 22, wherein:
- the layers of the implant define a plurality of through-holes extending from a first outer surface of the implant to a second outer surface of the implant opposite the first outer surface.
