InactiveUS6981981B2Improve clinical outcomesWorsen conditionSurgical furnitureInternal osteosythesisFilling materialsCancellous bone
Systems for treating a bone, e.g. a vertebral body, having an interior volume occupied, at least in part, by cancellous bone provide a first tool, a second tool, and a third tool. The first tool establishes a percutaneous access path to bone. The second tool is sized and configured to be introduced through the percutaneous access path to form a void that occupies less than the interior volume. The third tool places within the void through the percutaneous access path a volume of filling material. Related methods for treating a bone, e.g. a vertebral body, having an interior volume occupied, at least in part, by cancellous bone provide establishing a percutaneous access path to bone. A tool is introduced through the percutaneous access path and manipulated to form a void that occupies less than the interior volume. A volume of filling material is then placed within the void through the percutaneous access path.

Systems and methods for treating fractured or diseased bone using expandable bodies
Systems and methods treat fractured or diseased bone by deploying more than a single therapeutic tool into the bone. In one arrangement, the systems and methods deploy an expandable body in association with a bone cement nozzle into the bone, such that both occupy the bone interior at the same time. In another arrangement, the systems and methods deploy multiple expandable bodies, which occupy the bone interior volume simultaneously. Expansion of the bodies form cavity or cavities in cancellous bone in the interior bone volume.

A balloon for use in compressing cancellous bone and marrow (also known as medullary bone or trabecular bone). The balloon comprises an inflatable balloon body for insertion into said bone. The body has a shape and size to compress at least a portion of the cancellous bone to form a cavity in the cancellous bone and / or to restore the original position of the outer cortical bone, if fractured or collapsed. The balloon desirably incorporates restraints which inhibit the balloon from applying excessive pressure to various regions of the cortical bone. The wall or walls of the balloon are such that proper inflation of the balloon body is achieved to provide for optimum compression of the bone marrow. The balloon can be inserted quickly into a bone. The balloon can be made to have a suction catheter. The balloon can be used to form and / or enlarge a cavity or passage in a bone, especially in, but not limited to, vertebral bodies. Various additional embodiments facilitate directionally biasing the inflation of the balloon.

Controlled architecture ceramic composites by stereolithography
InactiveUS6283997B1Quality improvementFast preparationProgramme controlAdditive manufacturing apparatusCeramic compositeMetallurgy
A process for producing a ceramic composite having a porous network. The process includes providing a photocurable ceramic dispersion. The dispersion consists of a photocurable polymer and a ceramic composition. The surface of the dispersion is scanned with a laser to cure the photocurable polymer to produce a photocured polymer / ceramic composition. The photocured composition useful as a polymer / ceramic composite, or the polymer phase can be removed by heating to a first temperature that is sufficient to burn out the photocured polymer. It is then heated to a second temperature that is higher than the first temperature and is sufficient to sinter the ceramic composition to produce a purely ceramic composition having a porous network.Preferably and more specifically, the process uses a stereolithographic technique for laser scanning. The process can form a high quality orthopedic implant that dimensionally matches the bone structure of a patient. The technique relies upon laser photocuring a dense colloidal dispersion into a desired complex three-dimensional shape. The shape is obtained from a CAT scan file of a bone and is rendered into a CAD file that is readable by the stereolithography instrument. Or the shape is obtained directly from a CAD file that is readable by the stereolithography instrument.

Method and apparatus for reducing femoral fractures
InactiveUS7258692B2Reducing a hip fracturePrevent escapeInternal osteosythesisJoint implantsRight femoral headHip fracture
An improved method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps. After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur. After preparation of the femoral cavity, a femoral implant in accordance with the present invention is inserted into the aforementioned cavity in the femur. The femoral implant is thereafter secured in the femur, with portions of the implant extending into and being secured within the femoral head and portions of the implant extending into and being secured within the femoral shaft.

Method and apparatus for use of a non-invasive expandable implant
The present invention relates to a non-invasive expandable implant utilizing energy from an epiphyseal growth plate of a human long bone to expand the implant. A bone replacement section includes a housing, an expansion shaft, a connection system, and an implant member. An anchoring member is secured to the second bone portion and spaced from the implant member. The expansion shaft is configured to translate a first distance between the housing and the first bone member. Growth of the bone causes an increase of a second distance between an implant portion and the anchoring member. The increase of the second distance causes the anchoring member to exert a force on a connection system causing an increase of the first distance, thus expanding the implant.
