An expandable support device for tissue repair is disclosed. The device can be used to repair hard or soft tissue, such as bone or vertebral discs. A method of repairing tissue is also disclosed. The device and method can be used to treat compression fractures. The compression fractures can be in the spine. The device can be deployed by compressing the device longitudinally resulting in radial expansion.

Expandable support device and method of use

A minimaly invasive spacer for positioning between vertebral members. The spacer is adjustable between a first orientation having a reduced size to facilitate insertion between the vertebral members. A second orientation has an enlarged size for contacting the vertebral members. The spacer includes linkages that are attached to a pair of plates. A pull arm is operatively connected to the linkages for adjusting the spacer from the first orientation to the second orientation. A delivery device is attached to the spacer for insertion between the vertebral members. In one embodiment, the delivery device is detachable to be removed from the spacer once positioned between the vertebral members. Methods of using the spacer include positioning the spacer between the vertebral members while in the first orientation. The spacer is then enlarged to the second orientation, and the delivery device is removed with only the spacer remaining within the patient.

Minimally invasive expanding spacer and method

To secure a first body tissue with a second body tissue, a first anchor is moved along a first path through the first body tissue into the second body tissue. A second anchor is moved along a second path through the first body tissue into the second body tissue. A suture extending between the anchors may be tightened by moving the second anchor along a path which extends transverse to the path of the first anchor. The suture which extends between the anchors may have free ends which are connected with a suture retainer. The free ends of the suture may be interconnected either before or after the anchors are moved along the first and second paths. Alternatively, the suture may be a continuous loop which extends between the two anchors. A guide assembly may be provided to guide movement of the anchors along the two paths. The paths along which the anchors move may intersect so that the anchors may be interconnected at the intersection between the two paths.

Method of securing body tissue

Methods and devices are provided for intervertebral implant anchorage. An implantable device for insertion into an intradiscal section between adjacent vertebrae is provided. The implantable device includes at least one anchor plate which comprises a plate member sized to be positioned within an intradiscal section between adjacent vertebrae and a plurality of anchoring elements extending from a surface of the plate member, each anchoring element including a distal portion capable of being introduced into the vertebra through the vertebral end plate; and an intradiscal component coupled to the anchor plate.

Method and apparatus for intervertebral implant anchorage

An apparatus and method for implanting an intervertebral cage containing a bone graft and fusing adjacent vertebrae together while maintaining or correcting the angular alignment and balance of the spine. An improved method for anterior interbody fusion to form a fused bone segment having a predetermined fixed angular orientation. The apparatus has a fusion cage and has a set of expansion caps that operably expand the cage from which one is selected to adjust the orientation between adjacent vertebrae with facing surfaces at a predetermined angle relative to each other. A connecting bolt is threaded to the rear of the cage unit to hold the cap in position.

Anterior expandable spinal fusion cage system

An intervertebral body fusion device has a wedge body, a cage component with a plurality of deployable spines having end plate penetrating teeth, and a contraction mechanism for drawing the wedge body into the cage component. The device is surgically placed intervertebrally into the spine from an anterior surgical approach. In its final surgically-implanted position, the wedge body is substantially fully drawn within the cage component, resulting in a full deployment of teeth and associated spines into the adjacent end plates of the vertebral bodies, while simultaneously restoring the angle of lordosis to the spine.
