  • Patent number: 6533787
    Abstract: A staple for stabilizing the attachment of a vertebral screw and a longitudinal member to the spine. The staple has a plate with first and second apertures. All the staple's legs, prongs, or spikes attached to the underside of the staple are located closer to one particular aperture than the other. Preferably, the plate is also “bow-tie” shaped with a groove that separates the wings of the bow-tie. This bow-tie or hour glass shape combined with the groove help the surgeon to more easily conform the plate to the patient's vertebra.

  • Patent number: 6528466
    Abstract: A method of providing a solid oxidizer to a tank of water, while also providing a way to indicate when it is time to add more oxidizer. The preferred method includes providing the solid oxidizer in the form of an oxidizer shell with a coloring agent disposed therein. The coloring agent is substantially color stable when stored in the oxidizer shell, and the oxidizer shell is formed and shaped to enclose the coloring agent in a manner in which the coloring agent is prevented from dispersing into the water until the oxidizer shell is substantially dissolved.

  • Patent number: 6525334
    Abstract: An abrasive particle detention system includes a fluid circulation system, a probe assembly, a monitoring circuit, and an operator indicator. The probe assembly includes an orifice from which a stream of fluid emerges, and a probe having a face upon which the stream at least partially impinges. The probe face includes an insulative substrate and a conductive film formed on the substrate. Abrasive particles in the fluid stream abrade the conductive film, changing its electrical resistance. A monitoring circuit is utilized to observe these changes, and when they correspondence to a concentration above a pre-selected level, an operation indicator is triggered. The system may include an electronic controller coupled to the monitoring circuit, which can account for variables such as temperature, viscosity, and/or pressure in the fluid circulation system.

  • Patent number: 6520962
    Abstract: A connection assembly between a spinal implant rod and a vertebral anchor. The assembly has a longitudinal member, a housing, a rod interface washer, and a compression member. The longitudinal member has an aperture at one end and a wedge at the other. The housing has a passageway to accept the shank of a bone screw and a bore to accept the wedge. The bore is open to the passageway so that when the wedge is pulled from the bore it pushes against the shank of the bone screw, trapping the bone screw between the wedge and the sidewalls of the passageway. Threading a setscrew into the aperture presses a spinal rod against the washer, presses the washer against the housing, and pulls the wedge against the shank of the bone screw. Further tightening of the setscrew then locks the bone screw and rod together.

  • Patent number: 6521067
    Abstract: This invention relates to an apparatus and method for joining fabric, particularly for joining separate pieces of layered fabric, by means of waterproof seam in a single operation. The seam bonding apparatus comprises a hot-melt adhesive supply (20), a transducer (24) which supplies ultrasonic energy and a sonotrode (23) which directs the ultrasonic energy to an application point on the seam to be bonded. Adhesive, preferably molten nylon, is fed through a passage (25) in the sonotrode (23) via an exit aperture (28) at the end of the sonotrode to the application point. Local heat is applied to the other side of the seam at the application point, and the seam is then subjected to local cooling to form a permanent waterproof seam.
