Abstract

An intervertebral cage implant may include a first deployable keel, and a second deployable keel. A first portion of the first keel is configured to deploy from the cage in a generally superior direction and a second portion of the second keel is configured to deploy from the cage in a generally inferior direction to. The first keel is configured to deploy at a first angle less than 90° relative to a superior surface of the cage and the second keel is configured to deploy at a second angle less than 90° relative to an inferior surface of the cage. The first angle is substantially the same as the second angle, such that the first edge of the first blade is substantially parallel to the first edge of the second blade.

Dependent claims

An intervertebral cage implant, comprising:

a cage configured to be implanted between two vertebrae;
a first deployable keel, including a first blade, a first flange extending at an angle from a first edge of the first blade, and a second flange extending at an angle from a second edge of the first blade;
and
a second deployable keel, including a second blade, a third flange extending at an angle from a first edge of the second blade, and a fourth flange extending at an angle from a second edge of the second blade;
wherein a first portion of the first keel is configured to fit inside the cage in a first retracted position and deploy from the cage in a generally superior direction to a first extended position in which the first portion of the first keel is disposed superior to the cage of the implant;
wherein a second portion of the second keel is configured to fit inside the cage in a second retracted position and deploy from the cage in a generally inferior direction to a second extended position in which the second portion of the second keel is disposed inferior to the cage of the implant;
wherein the first keel is configured to deploy at a first angle less than 90° relative to a superior surface of the cage;
wherein the second keel is configured to deploy at a second angle less than 90° relative to an inferior surface of the cage;
and
wherein the first angle is substantially the same as the second angle, such that the first edge of the first blade is substantially parallel to the first edge of the second blade.
