An implant may include a peripheral structure, an opening for receiving part of an insertion device, and a plurality of bone contacting elements. A first lateral portion and an anterior portion are joined at a first corner portion of the peripheral structure and a second lateral portion and a posterior portion are joined at a second corner portion of the peripheral structure. Also, the opening is disposed in the first corner portion of the peripheral structure. Further, the opening has a central axis and the implant further includes at least three support beams including a first support beam extending along a second axis through a central portion of the implant from the anterior portion to the posterior portion of the peripheral structure. In addition, the second axis of the first support beam is oriented at an oblique angle with respect to the central axis of the opening.

Implant with a diagonal insertion axis

An implant may include a body including a ring, the ring further defining an opening, and the body defining a transverse plane dividing the implant into a superior half and an inferior half. The ring may also define a circumferential direction. The implant may further include a first outer member attached to the ring, wherein the first outer member extends outward in a direction away from the ring, wherein the first outer member defines one or more arches, and wherein the ring further defines a central channel extending through the implant.

Implant with structural members arranged around a ring

An implant may include a first body member and a second body member, at least one bone contacting arched member, and a first external element extending from the first body member to the second body member, wherein the first external element has an undulating planar geometry in which the first external element undulates in a single plane.

Implant with bone contacting elements having helical and undulating planar geometries

An implant may include a body including a ring, the ring further defining an opening, and the body defining a transverse plane dividing the implant into a superior half and an inferior half. The ring may also define a radial direction and a circumferential direction. The implant may further include a first outer member attached to the ring, wherein the first outer member extends radially from the ring, wherein the first outer member defines one or more arches, and wherein the ring further defines a central channel extending through the implant.

An implant for use in a spine includes a body and a plurality of structural members. The superior and inferior surfaces each include a ring and structural members arranged in a web-like pattern around the ring. Bone contacting members are arranged radially away from the ring and support members are arranged in a circumferential direction around the ring.

An implant including a first body member and a second body member and a first bone contacting element extending from the first body member to the second body member. The first bone contacting element may have a spiral configuration forming a plurality of arched members including at least two arched members extending substantially parallel to and offset with respect to one another.

An implant including a peripheral frame portion defining a periphery of the body; a first helical bone contacting member attached to the body and disposed within the superior half of the implant; and a second helical bone contacting member attached to the body and disposed within the superior half of the implant. The implant also includes a first support member extending inwardly of the bone contacting member into a central region of the implant; and a second support member extending inwardly of the bone contacting members. The first support member and the second support member are substantially U-shaped and are connected to one another at the bottoms of the two U-shapes in the central region.

Implant with supported helical members

An implant for insertion into a spine is configured with a body and a plurality of bone contacting elements. The implant is configured with an insertion axis that is diagonal to a lateral axis and to a posterior-anterior axis. The diagonal insertion axis allows for insertion of the implant using an oblique lumbar interbody fusion procedure.

An implant includes a central wall extending from a first side of a peripheral frame portion to a second side of the peripheral frame portion, and a first helical bone contacting member attached at the central wall and disposed within the superior half of the implant. The implant further includes a first support member attached at the central wall at a junction coincident with the first helical bone contacting member and extending to a central region of the implant internal to the first helical bone contacting member. In addition, the implant includes a non-helical bone contacting member extending from a portion of the first support member that is disposed internal to the first helical bone contacting member.

Implant with internal support members

A corpectomy implant is comprised of multiple layers of structural elements having a generalized helical geometry. These elements are separated by structural elements having an undulating planar geometry. The corpectomy implant also includes centrally located structural elements that have a closed loop geometry.

Corpectomy implant

An implant includes a first body member and a second body member connected by a plurality of bone contacting elements. Some of the bone contacting elements may have a generally helical geometry. Some of the bone contacting elements may have an undulating planar geometry. The bone contacting elements may have a rounded cross-sectional shape or a rectangular cross-sectional shape.

An implant includes a body including a peripheral frame portion defining a periphery of the body and a central wall extending from a first side of the peripheral frame portion to a second side of the peripheral frame portion. The implant may further include a first bone contacting member attached to the body and disposed within the superior half of the implant. Also, the implant may include a first support member extending from a first point on a superior side of the peripheral frame portion to the first the bone contacting member and further extending inwardly of the bone contacting member into a central region of the implant and terminating at a second point on an inferior side of the peripheral frame portion adjacent to the first point from which the first support member extends.
