| 20080306484 | APPARATUS FOR KNEE SURGERY AND METHOD OF USE - The present invention comprises a set of instruments and a method for their use in preparing a knee joint to receive knee implants. The inventive instruments and method are generally suitable for knee joint surgery. Furthermore, they include features that make them suitable for performing a minimally invasive knee surgery in which a smaller than normal incision is made and oriented to preserve the quadriceps mechanism and protect the suprapatellar pouch. The instruments permit switching from a minimally invasive technique to a standard open technique at any point in the procedure. An illustrative set of instruments for total knee arthroplasty and an associated minimally invasive technique are described. | 12-11-2008 |
| 20080306485 | INSTRUMENTS FOR KNEE SURGERY AND METHOD UF USE - The present invention comprises a set of instruments and a method for their use in preparing a knee joint to receive knee implants. The inventive instruments and method are generally suitable for knee joint surgery. Furthermore, they include features that make them suitable for performing minimally invasive knee surgery. | 12-11-2008 |
| 20090187251 | MODULAR BONE IMPLANT, TOOLS, AND METHOD - Modular bone implants, means of assembly, and their method of use are presented. | 07-23-2009 |
| 20100076567 | MODULAR FEMORAL COMPONENTS FOR KNEE ARTHROPLASTY - A femoral knee prosthesis system for resurfacing a resected articular surface at the distal end of a femur includes a femoral component adapted to mate with the resected articular surface; and an attachment member. The interior surface of the femoral component is configured to connect to the first attachment member when the femoral component is mated on the resected articular surface of the femur and when the first attachment member is passed through the medial side or the lateral side of the resected articular surface. The femoral component is available in one-piece and two-piece systems. Mating femoral components (e.g., tapered or with lips that interlock with grooves) are also disclosed. | 03-25-2010 |

| 20090082871 | METHOD AND APPARATUS FOR SPINE JOINT REPLACEMENT - A prosthesis for the replacement of the cartilaginous structures of a spine motion segment is described. The prosthesis comprises an intervertebral disc prosthesis in combination with a facet joint prosthesis. | 03-26-2009 |
| 20090171357 | COLLET FIXATION SYSTEM - A bone fixation assembly which may include a bone fixation element, a collet and a flexible line. The bone fixation element may comprise a first and second passageway and at least the first passageway is configured to receive the collet. The flexible line passes through both passageways and is secured through the second passageway. The collet may be advanced into the first passageway causing the collet to circumferentially engage the flexible line fixing it in place. Instrumentation for securing the collet includes a collet driver, a counter torque instrument and a tensioner. | 07-02-2009 |
| 20100010497 | SYSTEM AND METHOD FOR MENISCAL REPAIR THROUGH A MENISCAL CAPSULAR TUNNEL - A system for open or arthroscopic surgical repair of torn or damaged meniscal tissue has a repair member and an instrument. The repair member is a suture, flexible or rigid implant. The instrument has at a portion that is shaped to slide within a meniscal capsular tunnel. The meniscal capsular tunnel is an opening in the knee soft tissue passing from the anterior side of the knee adjacent to the mensical tissue to the posterior side of the knee in both the medial and lateral directions. The instrument interacts with the repair member to either insert it into the meniscus from the posterior side, or to facilitate securing of the repair member so that the repair member holds the meniscal tissue together on either side of a meniscal tear to foster healing of the damaged tissue. | 01-14-2010 |
| 20100030065 | SURGICAL ACCESS WITH TARGET VISUALIZATION - Accessing a spine from a curved postero-lateral approach may include a curved cannula positioned along a curved path from an opening in the skin to a location proximate to the spine. Positioning of the distal end of a radiolucent curved access cannula may be assisted by use of one or more radio-opaque markers. Markers may be positioned to form a cross hair image in fluoroscopy to assist in cannula placement. Radio-opaque inserts placed in and extended beyond the curved access cannula may have radiolucent windows to allow viewing of the cannula's radio-opaque markers. An appropriately placed curved access cannula may be clamped to prevent subsequent movement. Appropriate tools may be introduced through the curved access cannula and the distal radio-opaque tool heads may be viewed relative to the radio-opaque markers. The curved access cannula may be attached to the spine through one or more screws. | 02-04-2010 |
| 20100057129 | MULTIPLE FACET JOINT REPLACEMENT - A prosthesis for the replacement of multiple diseased or traumatized spinal facets comprises a portion that replaces at least a bony portion of the facets to be replaced and where the prosthesis attaches to the vertebra in a manner that does not require attachment to, or abutment against, the lamina. Multiple configurations of the prosthesis provide for replacement of the two inferior facets, the two superior facets, a superior and inferior facet, or all four facets. A method of installing the prosthesis is provided that is comprised of the steps of resecting at least a portion of the facets that carry the diseased or traumatized spinal facets and attaching the prosthesis in a manner that does not require attachment or abutment against the lamina. | 03-04-2010 |
| 20100069926 | LINE LOCK GRAFT RETENTION SYSTEM AND METHOD - A system for restoring articular cartilage has a cover, an anchor, and a tether that cooperate to retain graft tissue with respect to a graft site. The cover is attached to the anchor via the tether. The tether passes through a tunnel through a bone to which the articular cartilage is attached. The tunnel may be blind or may extend through the bone. The anchor is retained within the tunnel such that tension in the tether keeps the cover in place over the tissue graft. The anchor may receive the tether such that the tether can only pass through the anchor along one direction. Thus, tension applied to the tether between the anchor and the tissue graft is automatically maintained by the anchor. After passing through the anchor, the tether may exit the tunnel through the graft site, or through the opposite side of the bone. | 03-18-2010 |
