A device(100) and method(4100) for autologous bone graft harvesting simultaneously cuts a cross-section of a bone(900) longitudinally with a longitudinal drill assembly(102), and transversely with a saw assembly(126) during a bone(900) drilling to obtain a bone block for repairing and rebuilding diseased bones. The longitudinal drill assembly(102) and the saw assembly(126) simultaneously cut a cross-section of a bone(900). The device(100) is hand-controllable, drill motor powered, and spring-tensioned to selectively cut internally to the captured bone for internal bone harvesting. The longitudinal drill assembly(102) includes a drill shaft(114) extending perpendicular from a drill plate(112), having a flat surface(204) with a depth gauge(116). A module assembly(118) includes a module plate(120) disposed above the drill plate(112). Pins(302a,302b) extend from the upper face(308a) of the module plate(120) to engage ends of slots(400a,400b) to restrict over-rotation of saw plate(128). The saws (136a,136b) move between an open position(700a) for stowage, and a closed position(700b) while sawing the bone(900).

Implants and methods for augmentation, preferably by minimally invasive procedures and means, of body tissue, including in some embodiments repositioning of body tissue, for example, bone and, preferably vertebrae are described. The implant may comprise one or more chain linked bodies inserted into the interior of body tissue. As linked bodies are inserted into body tissue, they may fill a central portion thereof and for example in bone can push against the inner sides of the cortical exterior surface layer, for example the end plates of a vertebral body, thereby providing structural support and tending to restore the body tissue to its original or desired treatment height. A bone cement or other filler can be added to further augment and stabilize the body tissue. The preferred implant comprises a single flexible monolithic chain formed of allograft cortical bone having a plurality of substantially non-flexible bodies connected by substantially flexible links.

A device for safely approaching vertebral disc space utilizing stereotactic guidance, clearing material from the disc space, a device for expanding the disc space, stereotactic methods for implant planning and monitoring articulating instrument end effectors and a device for implantation into the disc space for the purpose of fusion or disc replacement.

An expandable support device for tissue repair is disclosed. The device can be used to repair hard or soft tissue, such as bone. The expandable support device can have interconnected struts. A method of repairing tissue is also disclosed. The expandable support device can be inserted into a damaged bone and radial expanded. The radial expansion of the expandable support device struts can cause the struts to cut mechanically support and/or the bone.

A kyphoplasty cannula includes a shaft extending between opposite first and second end surfaces. The shaft has an inner surface defining a lumen. The shaft has a first opening that extends through the first end surface and a second opening that extends through the second end surface. A scoop extends from the second end surface. The scoop has an arcuate inner surface that is continuous with the inner surface of the shaft an opposite outer surface. The scoop has a rib. Kits and methods of use are disclosed.

Inflatable orthopedic implants and related methods are disclosed herein, e.g., for deploying such implants within an intervertebral space for use in spinal fusion surgery, other intervertebral surgical procedures, or other surgical procedures. The inflatable intervertebral implant can include a hollow inflatable body that can be configured in a compact state for insertion into a target intervertebral space between a pair of adjacent vertebral bodies. Once the vertebral bodies are separated or distracted, e.g., using one or more inflatable distractors, the hollow body of the inflatable implant can be inflated with bone cement or other curable material. When the curable material hardens, the inflated implant can form a rigid intervertebral support structure (e.g., a fusion cage) capable of maintaining the vertebral distraction and thereby enabling removal of the distractors.

Implants and methods for augmentation of the disc space between two vertebral bodies to treat disease or abnormal pathology conditions in spinal applications. The implant includes a chain of biocompatible material suitable for insertion into a disc space between two adjacent vertebral bodies in a patient's spinal column, wherein the spinal disc space has a transverse plane. The chain comprises a plurality of adjacent bodies having a height configured to reside within the disc space between two adjacent vertebral bodies and a length configured to reside in the disc space between two adjacent vertebral bodies when the chain is curved in an orientation substantially along the transverse plane of the spinal disc space.

The present invention relates to a kit for stabilizing an implanted device. The kit komprises a composition for stabilizing an implanted device, and a syringe for introducing the composition into an implanted device. The composition is a composition comprising a solidifying fluid, an initiator adapted to exert influence on a solidifying fluid, and a mixture of a solidifying fluid and an initiator.

Method and apparatus for performing medial-to-lateral sacroiliac fusion. An aiming guide is used to place a guide wire into a sacroiliac joint to facilitate driving a fusion implant into the joint.

A method for stabilizing a leaking implanted device capable of being hydraulically adjusted by introducing or withdrawing hydraulic fluid to/from the device, the device having an inner space for enclosing the hydraulic fluid. The method comprises at least one of the steps of introducing at least one of: a solidifying fluid, an initiator adapted to exert influence on a solidifying fluid or the hydraulic fluid, and a mixture of a solidifying fluid and an initiator, into said leaking implanted hydraulically adjustable device for solidifying the solidifying fluid or the hydraulic fluid for permanently defining the volume and/or shape of the device, and repairing a leakage, puncture or rupture of the implanted hydraulically adjustable device by the introduction of a sealing component which forms a layer on the inside of the implanted hydraulically adjustable device preventing further leakage with retained function of the device, such that the repaired implanted hydraulically adjustable device can be hydraulically adjusted by introducing or withdrawing fluid to/from the device.
