Abstract

An implant may include a body having a first portion and a second portion and a structural member having a central member curve. In addition, the structural member may be exposed on an outer surface of the implant. Further, the central member curve may include a winding segment, and the winding segment of the central member curve may wind around a fixed path extending from the first portion of the body to the second portion of the body. Also, the central member curve may make one or more full turns around the fixed path. And, the structural member may have a member diameter at the winding segment, wherein the winding segment has a winding diameter corresponding with the full turn around the fixed path and the member diameter is greater than the winding diameter.

Dependent claims

An intervertebral implant, comprising:

a bone contacting outer member having an elongate geometry;
and
a support member having an elongate geometry;
wherein the support member is attached to the outer member;
wherein the outer member has a central member curve;
and
wherein the central member curve is non-linear;
wherein the outer member has a bone contacting outer surface configured to contact a vertebra;
