摘要:
Some embodiments of the invention provide an apparatus that (1) delivers a fusion member between two vertebral bodies after at least a portion of the fibrocartilaginous disc between the vertebral bodies has been removed, and (2) affixes the fusion member to the vertebral bodies. In some embodiments, the apparatus includes (1) a fusion member that is delivered and positioned between the vertebral bodies, (2) a delivery mechanism that delivers and positions the fusion member between the vertebral bodies, and (3) an anchoring member that affixes the fusion member to the vertebral bodies.
摘要:
A shroud for protecting exterior portions of a prosthetic implant from adhesive and a method for utilizing the same. The shroud includes a hub, a rim, and at least one bridge connecting the hub and the rim. The rim of the shroud may be sized to cover substantially the same area as a guard of the implant. The method of utilizing the shroud involves securing the shroud to the prosthetic implant. A quantity of adhesive is provided, and the prosthetic implant is secured thereto. The shroud is removed from the implant, and then the guard is secured to the implant.

A system for assisting in a surgical process, comprising: (a) a surgical device taken from a group consisting of a surgical tool and a surgical implant; (b) a positional sensor carried by the surgical device, the positional sensor including a wireless transmitter and associated circuitry for transmitting sensor data from the transmitter; and (c) a computer system including a wireless receiver and signal conditioning circuitry and hardware for converting sensor data received by the wireless receiver into at least one of (i) audio feedback of positional information for the surgical device and (ii) visual feedback of positional information for the surgical device.
摘要:
The invention provides an implantable spinal distraction/fusion rod with varied thread pitch and diameters along different portions of its length that it is capable of distracting two or more vertebral bodies relative to each other and/or facilitating the procedure of fusing the vertebral bodies together from within the spine. The present invention also provides for methods of using the rod to distract and/or fuse two or more vertebral bodies from within the spine.

摘要:
A biocompatible, resorbable collagen membrane containment member for a bone regenerative material, and a method of using such a containment member to regenerate a bone defect by surgically accessing the bone defect; disposing the containment member adjacent the bone defect, and thereafter injecting a bone regenerative material into the containment member.
摘要:
Methods for correcting a deformity in the spine by forming a trans-sacral axial instrumentation/fusion axial bore through vertebral bodies in general alignment with a visualized, anterior axial instrumentation/fusion line in a minimally invasive, low trauma, manner and providing a therapy to the spine employing the axial bore. Curved or relatively straight anterior axial bores are formed from the anterior starting positions. The therapies performed through the axial bores include discoscopy, full and partial discectomy, vertebroplasty, balloon-assisted vertebroplasty, drug delivery, electrical stimulation and various forms of spinal disc cavity augmentation, spinal disc replacement, fusion of spinal motion segments and implantation of radioactive seeds. Axial spinal implants and bone growth materials can be placed into single or multiple parallel or diverging axial bores to fuse two or more vertebrae, or distract or shock absorb two or more vertebrae.
