| 20080269762 | METHOD AND DEVICE FOR REPAIR OF CARTILAGE DEFECTS - Methods for repairing a cartilage defect in a subject, such methods comprising placing a tissue specimen into a container, centrifuging the container to separate the specimen into at least three fractions, drawing a selected fraction from the container, processing the fraction into a therapeutic composition, and treating the cartilage defect with the therapeutic composition. | 10-30-2008 |
| 20080262624 | Patient-Modified Implant And Associated Method - An orthopedic implant. The implant has a first portion including at least one patient-adjustable feature, and a second portion including at least one standard feature. | 10-23-2008 |
| 20080257363 | Method And Apparatus For Manufacturing An Implant - An orthopedic implant manufacturing method. The method includes preparing a preliminary pre-operative surgical plan for a specific patient, communicating the plan to a surgeon of the patient, and receiving an orthopedic implant design recommendation of the surgeon. The implant design recommendation can include selecting one of first, second or third options, the first option being a patient-specific implant, the second option being a semi-custom implant, and the third option being an off-the-shelf implant. The method further includes sending a request for manufacturing the selected implant to a manufacturing center, receiving the implant, and forwarding the implant for implantation. | 10-23-2008 |
| 20080234830 | Femoral Head Having A Spherical Backside Surface - A prosthesis member or assembly can be implanted in a portion of the anatomy. The prosthesis member, with various portions, defines a selected amount of a sphere to articulate or engage selected portions of the anatomy. | 09-25-2008 |
| 20080228189 | Distal femoral cutting guide - A system locates a femoral cutting guide on a distal end of a femur. The femoral cutting guide establishes at least a first reference plane to perform a distal femoral planar cut. The system generally includes a mounting rod operable to insert into the distal end of the femur. An index member is operable to abut the distal end of the femur. A bridge member extends from the index member. A cutting guide member extends from the bridge member. The cutting guide member includes a first channel that establishes the first reference plane. A mounting mechanism releasably couples the cutting guide member to the bridge member. The mounting mechanism is operable to generate a sliding resistance between the bridge member and the cutting guide member that is generally overcome to position the cutting guide member relative to the femur. | 09-18-2008 |
| 20080221699 | Method and apparatus for removing an acetabular bearing - A system for replacing a portion of a hip joint can include a cup having an outer surface and an inner surface. A bearing can include an outer bearing surface and an inner articulating surface. The outer bearing surface can be positioned adjacent to the cup. A ring can be selectively disposed between the cup and the bearing. The ring can define an annular body having a slit formed therein. A removal tool can define a proximal end and a distal end. The distal end can define a ring engaging surface and a bearing engaging surface. The ring engaging surface can be adapted to engage the ring at the slit such that the ring expands radially from a locked position away from engagement with the bearing to an unlocked position. The bearing engaging surface can be adapted to engage the bearing and urge the bearing away from the cup. | 09-11-2008 |
| 20080217265 | Apparatus And Method for Separating And Concentrating Fluids Containing Multiple Components - An apparatus is disclosed that allows for separating and collecting a fraction of a sample. The apparatus, when used with a centrifuge, allows for the creation of at least three fractions in the apparatus. It also provides for a new method of extracting the buffy coat phase from a whole blood sample. A buoy system that may include a first buoy portion and a second buoy member operably interconnected may be used to form at least three fractions from a sample during a substantially single centrifugation process. Therefore, the separation of various fractions may be substantially quick and efficient. | 09-11-2008 |
