摘要:
This invention relates to a metal composite orthopedic device. The device can comprise a metallic substrate cladded or joined to one or more metallic layer(s). The substrate and metallic layer(s) can be selected of different metals and metal alloys to provide desired wear performance, imaging characteristics and optionally to serve as a reservoir for therapeutic agents.
摘要:
Described are artificial disc implants for insertion between first and second adjacent vertebrae in a patient. The implants have a first member and a second member in articulating relationship. At least one member of the implant includes an amorphous metal element. Also described are related methods of making and using artificial disc implants.
摘要:
This invention relates to an implantable medical device to treat a patient. The implantable device can be an orthopedic device such as a spinal implant including, but not restricted to, a disc or nucleus pulposus prosthesis, a spinal rod assembly, or a bone fixation plate. The orthopedic device can be formed to include a metal matrix composite that provides enhanced wear and diagnostic imaging techniques. In other forms, the present invention provides an implantable medical device that includes a porous metal matrix composite that can deliver a therapeutic composition to a patient. In still other forms, the present invention provides an implantable electrical device or lead formed to include a metal matrix composite that provides lower polarization and interfacial impedance and allows enhanced sensing of the physiological signals.
摘要:
Methods for forming a shaped surface, for example, a shaped end plate between adjacent vertebral bodies, and a bone removal device for use in such methods. The device includes a contour having a predetermined profile corresponding at least in part to an implant, and a cutting element following the contour and having a cutting edge having a profile corresponding to the contour profile.
摘要:
A prosthetic device according to which a time-dependent degree of resistance is provided to at least one predetermined type of relative directional motion between first and second components of the device.
摘要:
Methods and devices for providing a stabilized implant at a site of implantation include providing locking members on faces of the implant and applying bone cement to the implant faces. The locking members secure the bone cement so that the bone cement will not be substantially displaced when the implant is inserted at an implantation site.
摘要:
A method of, and apparatus for, arthroplasty of a knee joint comprising obtaining a desired spacing of the femur from the tibia by inserting a spacer into the knee joint between the femur and the tibia. The spacer is used as a reference for securing a guide jig in position about the knee joint for guiding resection of one or both of the femur and tibia for fitting of tibial and/or femoral prostheses. A method of resecting the femur while moving the tibia through an arc of motion to remove bone to the desired depth, a method of determining the position of the guide jig, the guide jog, an alignment device and the spacer are also described.
摘要:
A system for affixing at least two portions of bone is provided. The system has a first end cap, a second end cap, and a linking member extending between the first end cap and the second end cap, wherein the first end cap has at least one leg configured to connect the linking member to the first end cap and configured to retain said connection.
摘要:
An artificial disc implant and associate methods and instrumentation are provided for the artificial disc implant that includes opposite vertebral endplate members and a spacer member between the vertebral endplate members. An anchoring member extends from at least one of the vertebral endplate members toward an adjacent vertebral endplate when the implant is positioned between vertebrae. The anchoring member can be received in an anchor seat formed in the adjacent vertebral endplate without requiring the artificial disc implant to be impacted into the space between vertebrae to engage the anchoring member in the seat.
摘要:
An intervertebral disc space preparation guide comprises a spacer portion having a first recess and a first machining guide comprising a first bore. The first bore and the first recess are aligned and adapted to receive a first bone removal mechanism.
