Abstract
A spinal interbody implant includes an outer portion and an inner portion surrounded by the outer portion and having a plurality of channels. The inner portion has a greater porosity than that of the outer portion.
Claims20
A spinal interbody implant comprising:
- an outer portion having a first porosity;
- and
- an inner portion extending from a first end of the implant to a second end of the implant, the inner portion peripherally surrounded by the outer portion and having a plurality of channels extending therethrough and a second porosity greater than the first porosity,
- wherein the outer portion defines a hollow space therewithin having a size greater than a size of a space defined by each of the plurality of channels, the hollow space at least partially enclosed on all sides by the outer portion.

A spinal interbody implant comprising:
- an outer portion forming a first part of a top surface of the implant;
- an inner portion disposed within the outer portion, the inner portion forming a second part of the top surface of the implant;
- and
- a first channel extending through the outer portion and the inner portion, a first end of the first channel being on a lateral surface of the implant and a second end of the first channel opposite the first end being on the top surface or a bottom surface of the implant,
- wherein the inner portion is more porous than the outer portion.
2 more elements
An implant comprising:
- an outer shell including a first endplate surface and a second endplate surface, the first endplate surface and the second endplate surface being separated by a lateral wall of the outer shell;
- a fill material disposed within the outer shell, the fill material including a first layer and a second layer enclosing the first layer, the first layer having a first porosity and the second layer having a second porosity less than the first porosity
- a first plurality of channels extending through the outer shell and the fill material with opposite ends at an outer surface of the lateral wall, the first plurality of channels being at a first distance from the first endplate surface;
- and
- a second plurality of channels each being at a second distance from the first endplate surface, the second distance being less than the first distance,
- wherein the fill material is more porous than the outer shell.
