    Abstract: Allogenic or xenogenic materials are used to provide intervertebral disc nucleus implants and/or annular plugs. The allogenic or xenogenic materials comprise natural disc annulus material, which may have a portion of the anterior longitudinal ligament attached. The tissue may be used “as is” without an additional core or covering, or it may be used in combination with other materials. The material may be rolled, folded, layered and/or sutured, stapled, or glued to provide a solid plug of natural biological material. The implant may be provided as a dehydrated, substantially rod-shaped segment having a diameter less than the diameter of the hydrated material, and may have one or more ends of the dehydrated rod terminate with a further reduced diameter portion, preferably a point.

  • Patent number: 8906098
    Abstract: A device for introduction into a body in a straight configuration and assuming within the body a predefined curved configuration, includes an elongated element formed from a number of segments interconnected so as to form effective hinges therebetween. When the elongated element is confined to a straight state, the effective hinges transfer compressive forces from each segment to the next so that the elongated element can be pushed to advance it through a conduit. When the elongated element is not confined to a straight state, the effective hinges allow deflection of each segment relative to adjacent segments until abutment surfaces of the segments come into abutment, thereby defining a fully flexed state of the elongated element with a predefined curved configuration. The device can be produced with a wide range of two-dimensional and three-dimensional curved forms, and has both medical and non-medical applications.

    Abstract: A prosthetic device includes one or more components configured to be disposed in a joint. The component includes at least one feature configured to provide information about the component. The information can be used to determine or create the relationship between the component and the joint and/or other components. This relationship may be used to evaluate and/or modify the expected performance of the prosthetic device and assist in determining the optimal relationship between one or more components and a patient's anatomy.

  • Patent number: 7780735
    Abstract: A total knee arthorplasty in accordance with the teachings of the present invention is accomplished by surgically removing the meniscus and adjacent joint end portions of the femur and tibia and then replacing the first one of the removed joint end portions with a first prosthetic component. Thereafter a flexible protector shim is temporally inserted between the first prosthetic component and the other of the joint end portions. Then the other of the removed joint end portions is replaced with a second prosthetic component while the protector shim is maintained in position between the prosthetic components for thereby preventing scarring, scratching and minimizing movement during the cement curing phase of the insertion process. The protector shim is thereafter removed and a prosthetic meniscus is inserted between the two prosthetic components.

  • Patent number: 7771482
    Abstract: Bioresorbable inflatable devices and tunnel incision tool and methods for treating and enlarging a tissue or an organ or a tube or a vessel or a cavity. The device is composed of a hollow expanding pouch made of a resorbable material that can be attached to a filling element. The pouch can be filled with a biocompatible materials, one or more times in few days interval, after the insertion of the device. While filling the pouch every few days the tissue expands and the filling material if it is bioactive start to function. The tunnel incision tool composed of a little blade that emerges from the surface of the tool in order to make shallow incisions in the surrounding tissue therefore enabling easy expansion of the tissue.

  • Patent number: 7708776
    Abstract: An improved total disc replacement system and related methods, wherein a pair of anchor plates, each adapted to engage a vertebral body, and a translating internal member are provided. The translating internal member boasts the ability to move or translate between the anchor plates without compromising the conformity of the interface between the translating internal member and the anchor plates. In a significant aspect, the anchor plates may be locked in place relative to one another after implantation to effect fusion between the vertebral bodies.

  • Patent number: 7695519
    Abstract: A modular keel or stem for use as a tibial implant has a central stem portion including a tongue-like coupling portion for insertion into a grooved portion in a bone contacting portion of a tibial baseplate. The modular keel or stem may also include a pair of anti-rotation fins or ribs which extend medially and posteriorly on the medial side and laterally and posteriorly on the lateral side. Proximal portions of the ribs or fins may engage receptacles in the bone contacting of the tibial baseplate. A locking element is provided for engaging the keel or stem coupling portion and the baseplate after the coupling portion of the keel is inserted into the groove to prevent the disassembly the keel from the baseplate. In one embodiment, the baseplate is capable of being inserted in a direction offset from the anterior-posterior direction, such as a medial-lateral direction, after the keel has been implanted. A polymeric bearing insert is provided for placement onto the baseplate in a standard manner.

  • Patent number: 7637911
    Abstract: A method of replacing at least a portion of an intervertebral disc of an intervertebral disc space of a spinal column, the intervertebral disc space defined at least by respective endplates of first and second adjacent vertebral bones, the method comprising the steps of inserting at least one intervertebral disc replacement trial into the intervertebral disc space to distract same in a direction along a longitudinal axis of the spinal column and simultaneously inserting first and second members of an intervertebral disc replacement device into an intervertebral disc space of the spinal column. The method also comprising maintaining first and second articulation surfaces of the respective first and second members of an intervertebral disc replacement device as a single assembly by way of an insertion plate. This may include the use of an insertion handle that is adapted to detachably engage the insertion plate.

  • Patent number: 7527648
    Abstract: A method of reconstructing a ruptured anterior cruciate ligament in a human knee. Femoral and tibial tunnels are drilled into the femur and tibia. A transverse tunnel is drilled into the femur to intersect the femoral tunnel. A replacement graft is formed into a loop and moved into the femoral and tibial tunnels using a surgical needle and suture. A flexible filamentary member is simultaneously moved along with the loop into the femoral and transverse tunnels. A pin passing member maintains one end of the filamentary wire in the transverse tunnel as the graft is being moved into place in the femoral and tibial tunnels. The filamentary member is used as a guide wire in the transverse tunnel to insert a cannulated cross-pin to secure a top of the looped graft in the femoral tunnel.
