Implant with Improved Bone Contact
An intervertebral implant includes a body formed as an open lattice structure by a plurality of struts. Some of the struts of the plurality of struts intersect at nodes. The nodes can include an enlarged contact member that extends over the node and at least a portion of the width of some of the struts. Enlarged contact members may have an asymmetrical shape with respect to the intersection of struts. The enlarged contact members can provide improved bone contact for the implant. The plurality of struts can have a cross-sectional shape that includes a flattened portion. The flattened portion of the plurality of struts can provide improved bone contact for the implant. An additive manufacturing process can be used to build the implant in a substantially vertical direction.
IMPLANT WITH A DIAGONAL INSERTION AXIS
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.
INTERBODY FUSION DEVICE
Devices for fixing interbody fusion devices to bone by helically or corkscrew-shaped elements are provided. Methods for surgically implanting an interbody fusion device using helically-shaped fixation wire are provided.
FLEXIBLE POROUS IMPLANT FIXATION SYSTEM
The present disclosure relates to flexible porous implant fixation systems. Certain aspects provide flexible porous structures including a helicoidal structure and a plurality of interlocking elements coupled to the helicoidal structure, the helicoidal structure being configured to connect the plurality of interlocking elements. Certain aspects provide a body comprising a porous structure, the body configured to interface with a bone perpendicular to an axis of the bone; and a screw comprising a head, wherein the head is configured to lie within a volume of the body while a portion of the screw extends away from the body, wherein the body is configured to restrict movement of the head within the body along the axis of the bone.
Flexible Chain Implants and Instrumentation
A flexible chain implant for insertion into an interior volume of a vertebral body. The implant may be implanted in an insertion position for sliding through a cannula and is flexible for packing into the interior volume in an implanted configuration. The implant randomly separates in the implanted configuration. The implant includes a top member and a bottom member, wherein the top and bottom members are coupled to one another at a coupled portion. The top and bottom members preferably each include an inner surface such that the inner surfaces include a plurality of alternating projections and recesses so that the projections are received within the recesses in an insertion position. Alternatively, the implant may include a plurality of substantially non-flexible bodies and a plurality of substantially flexible links interconnecting the bodies. The non-flexible bodies include a plurality of facets and/or abutment surfaces.
Stent
A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.
INSTRUMENTS AND METHODS FOR POSTERIOR SURGICAL APPROACH FOR SACROILIAC JOINT
Improved tools and methods of fusing human joints, such as the sacroiliac joint are disclosed. The methods use intra-articular joint fusion device(s) for fixing the articular surfaces relative to one another, The fusion implants may have fixation element(s) for engagement with bone tissue in the articular surfaces of the targeted joint. The present invention includes a novel washer device operable to stabilize instruments and the joint fusion implant.

Implant With Structural Members Arranged Around A Ring
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.
