Expansible intervertebral implant

An intervertebral implant comprising:

• a baseplate forming a proximal end of the intervertebral implant;
• a superior arm articulable from a coupling point on a superior portion of the baseplate, the superior arm extending along a primary axis and articulable in both a secondary axis and a tertiary axis;
• an inferior arm articulable from a coupling point on an inferior portion of the baseplate, the inferior arm extending along the primary axis and articulable in both the secondary axis and the tertiary axis;
• and
• an expansion mechanism including a pair of lateral branches operable upon engagement of an insert to translate the expansion mechanism along the primary axis causing expansion of the superior arm and the inferior arm along the secondary axis and the tertiary axis, wherein the insert includes an elongate hollow externally threaded cylinder and wherein, during implantation of the implant between adjacent vertebrae, an elongated deployer engages the baseplate between the superior and inferior arms to guide the implant into a desired position between the adjacent vertebrae and a connection rod is telescopically received within the elongated deployer and elongate hollow externally threaded cylinder to engage the elongate hollow externally threaded cylinder, rotation of the elongate hollow externally threaded cylinder by the connection rod translating the expansion mechanism along the primary axis.

An intervertebral implant comprising a body extending longitudinally along a primary axis, the intervertebral implant comprising:

• a baseplate disposed at a proximal end of the body and configured to engage an implant holder tube during deployment of the intervertebral implant between adjacent vertebrae;
• opposing first and second elongated arms disposed along the primary axis and each including a vertebral support surface, each of the first and second elongated arms articulable relative to the baseplate such that the intervertebral implant comprises a collapsed position in which the first and second elongated arms are close to each other and a deployed position in which the first and second elongated arms are separated from each other along a secondary axis and a tertiary axis;
• a hooking device pivotably engaging the first and second elongated arms;
• and
• an insert including an externally threaded hollow cylinder, wherein, during implantation, an elongated deployer is telescopically received within the implant holder tube to engage the insert interiorly of the opposing first and second elongated arms and guide the implant into a desired position between the adjacent vertebrae and a connection rod is telescopically received within the elongated deployer and externally threaded hollow cylinder to engage the hooking device to cause articulation of the first and second elongated arms relative to the baseplate to expand the intervertebral implant along the secondary axis and the tertiary axis.
