  • Patent number: 6454807
    Abstract: An apparatus and method for implanting an articulated spinal fusion cage into the intervertebral space and adjusting the cage in situ to support the adjacent vertebrae in a normal curved alignment. The invention provides a greatly improved modular cage system having a base unit with a pair of sockets for receiving the ends of a pair of legs. The sockets permit pivotal movement of the legs about a posterior fulcrum from a closed, parallel insertion position to an anteriorly open, wedge-shaped orientation. The base has a threaded bore for receiving a driver, which is operable to urge the anterior ends of the legs apart as well as to support the front of the installed fusion cage. Interchangeable drivers are provided having various sized tips. The interior end surface of each leg unit includes a driver-receiving groove for providing torsional stability. Alternatively, a pair of pins and bores are provided on the inner surfaces of the opposed ends for receiving a driver tip.

  • Patent number: 6443987
    Abstract: A spinal vertebral implant includes a substantially rectangular shaped base section made from a solid piece of bone. A nose section extends integrally from the substantially rectangularly shaped base section and preferably has a generally tapering shape to foster entry between adjacent vertebrae. The nose section tapers distally and inwardly from the base section to form a generally pointed or rounded distal tip portion and comprises a solid piece of bone. Serrated sides assist the implant in gripping adjacent upper and lower vertebrae and in being maintained therebetween. The serrated sides are angled in a manner that encourages the implant to be placed between the vertebrae and locked therebetween upon such placement. First and second implants may be placed into respective left and right sides of an intervertebral space. A method for placing one or more implants between the adjacent vertebrae comprises forming a slot configured to receive an implant and inserting the implant into the slot.

  • Patent number: 6432132
    Abstract: An expandable intraluminal endoprosthesis comprises a tubular member having a first and second end and a wall surface disposed between said first and second end. The wall has a first diameter in a first, unexpanded state which permits intraluminal delivery of the member into a lumen of a body passageway, particularly a blood vessel, whilst being capable of acquiring a second diameter in an expanded and deformed state upon the exertion of a radially outwardly extending force to expand the lumen of the body passageway. At least a part of said wall of said tubular member comprises, at least one substantially continuous winding of mutually staggered primary undulations advancing substantially helically along a longitudinal axis of said tubular member. A first primary undulation is connected to an associated second primary undulation by means of a first connection element.

  • Patent number: 6419704
    Abstract: Artificial disc replacements for natural intervertebral discs make use of a shaped body having a final volume sized to consume at least a portion of an intervertebral disc space, and a filling within the shaped body enabling the body to cyclically compress and expand in a manner similar to the disc material being replaced. The filling may be a gas, liquid or a gel, in which case the body further includes valve means enabling the body to be filled, preferably following introduction into the disc space. Depending upon the application and other factors, one or more of the bodies may be used in the same disc space, and each may be provided according to different embodiments to distribute compressive stress or to meet other considerations. One or both of the top and bottom surfaces of the shaped body may configured to increase friction so as to maintain the body within the intervertebral space.
