  • Publication number: 20080045958
    Abstract: An embodiment of a system in accordance with the present invention can include an implant having a spacer with a thickness and a wing, wherein a first configuration of the wing has a first height substantially similar to the thickness and wherein the wing is adapted to be selectably arranged in a second configuration such that the wing has a second height greater than the first height. A periphery of the implant has a shape generally conformal with a shape of an inner surface of a cannula and a cross-sectional diameter smaller than an inner diameter of the cannula. The cannula is inserted such that a proximal end of the cannula is arranged between the adjacent spinous processes. The implant is then urged into position between the adjacent spinous processes by way of the cannula, and subsequently arranged in a second configuration to fix the implant in position.

  • Publication number: 20080046086
    Abstract: Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a spacer and a frame having a central body and a helical shaped wing extending from the central body. The frame can be positioned near about adjacent spinous processes, and can be rotated and urged so that the adjacent spinous processes pass within a groove of the wing, thereby allowing the wing to be arranged on an opposite side of the adjacent spinous processes. The spacer can then be arranged over the frame so that the spacer contacts and distracts the spinous processes, thereby limiting relative movement of the adjacent spinous processes during extension.

  • Publication number: 20080046081
    Abstract: Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a first wing, a spacer extending from the first wing, and a distraction guide. The distraction guide is arranged in a first configuration to pierce and/or distract tissue associated with adjacent spinous processes extending from vertebrae of a targeted motion segment. The implant can be positioned between the adjacent spinous processes and once positioned, the implant can be arranged in a second configuration. When arranged in a second configuration, the distraction guide can act as a second wing. The first wing and the second wing can limit or block movement of the implant along a longitudinal axis of the implant.

  • Publication number: 20080027435
    Abstract: Systems, procedures and tools for repairing, or reinforcing the spinous process. The systems and procedures provide for injecting bone cement into and optionally around the spinous process. Additional reinforcing elements may be embedded in the bone cement inside or outside the spinous process. The procedures include positioning of the guide and reinforcing elements relative to a spinous process, preparation of the spinous process for injection and injection of bone cement into the spinous process. Tools are provided to facilitate the accurate injection of bone cement. The systems and procedures increase the strength of the spinous process and enhance the applicability and outcome of spinal interventions.

  • Publication number: 20070276500
    Abstract: Systems in accordance with embodiments of the present invention can include an implant comprising a spacer for defining a minimum space between adjacent spinous processes, a distraction guide for piercing and distracting an interspinous ligament during implantation, and a binder for limiting or preventing flexion motion of the targeted motion segment. The binder can be secured to a brace associated with the implant during implantation by a capture device. A binder aligner aligns the binder with the implant stabilizing the implant, binder and the adjacent vertebrae.

  • Publication number: 20070148089
    Abstract: Described is a novel family of cell surface serpentine transmembrane antigens. Two of the proteins in this family are exclusively or predominantly expressed in the prostate, as well as in prostate cancer, and thus members of this family have been termed “STEAP” (Six Transmembrane Epithelial Antigen of the Prostate). Four particular human STEAPs are described and characterized herein. The human STEAPs exhibit a high degree of structural conservation among them but show no significant structural homology to any known human proteins. The prototype member of the STEAP family, STEAP-1, appears to be a type IIIa membrane protein expressed predominantly in prostate cells in normal human tissues. Structurally, STEAP-1 is a 339 amino acid protein characterized by a molecular topology of six transmembrane domains and intracellular N- and C-termini, suggesting that it folds in a “serpentine” manner into three extracellular and two intracellular loops.

  • Publication number: 20070114185
    Abstract: A process for removing selenium from a water stream, in particular a waste water stream, by: 1) the addition thereto of a ferric salt, followed by 2) the addition of a cupric salt and pH adjustment to a pH value in the range of from about 6.5 to about 8.0, thereby forming a copper-and-selenium-containing precipitate, and 3) removing the copper-and-selenium-containing precipitate to thereby form a treated water stream, is disclosed. The optional precipitation and removal of excess copper ions is also disclosed.
