Bidirectional fixating intervertebral implant system

A bidirectional fixating intervertebral implant system, the system comprising:

• at least one implant body comprising polyether ether ketone (PEEK) configured to act to reduce subsidence of a disc space between first and second vertebral bodies when implanted into the disc space, the implant body having a first vertebral body-facing surface having a first set of ridges and an opposing second vertebral body-facing surface having a second set of ridges configured for engaging the first and second vertebral bodies, wherein the first vertebral body-facing surface defines a first anchor opening and wherein the second vertebral body-facing surface defines a second anchor opening, wherein the implant body has a body top surface, a body bottom surface, and first and second body side surfaces that combine to define a body perimeter extending around the implant body between the first and second vertebral body-facing surfaces;
• a perimeter enclosure comprising titanium and extending around and connected to the body perimeter of the implant body, wherein the perimeter enclosure surrounds and covers at least part of the body top surface, the body bottom surface, and the first and second body side surfaces while exposing the first and second vertebral-body facing surfaces so as to allow the first and second vertebral body-facing surfaces to abut the first and second vertebral bodies when the implant system is implanted in the disc space, wherein the implant body and the perimeter enclosure are sized to fit within the disc space when the implant body and the perimeter enclosure are combined and implanted in the disc space, wherein the perimeter enclosure defines at least one tool hole extending through the perimeter enclosure to the top surface of the implant body;
• a first anchor sized and configured to extend through the first anchor opening from a position that is internal to the at least one implant body to a position that is external to the at least one implant body, wherein the first anchor has a first shaft portion sized and configured to extend through the first anchor opening and a first vertebral body engagement portion extending laterally outward from the first shaft portion in multiple directions to engage the first vertebral body when the implant system is positioned in the disc space;
• and
• a second anchor sized and configured to extend through the second anchor opening from a position that is internal to the at least one implant body to a position that is external to the at least one implant body, wherein the second anchor has a second shaft portion sized and configured to extend through the first anchor opening and a second vertebral body engagement portion extending laterally outward from the second shaft portion in multiple directions to engage the second vertebral body when the implant system is positioned in the disc space.
