  • Publication number: 20070062859
    Abstract: A fluid filtration unit having two or more filter medium layers and/or zones, at least one of the layers/zones having a different particle retention capability disposed on each side of a non-filtering separator element. The filter medium are presently preferably positioned such that each succeedingly distal filter layer or zone from the separator has a decreased particle retention capability than each proceeding filter layer or zone. The filter medium layer most proximal to the separator element may be separated from the separator by a support material for supporting such filter medium element and preventing collapsing of the medium into any separator conduit. At least one of the medium elements is formed from a material which swells in size due to fluid absorption with the various zones and the separator being operatively connected by a new and innovative edge seal.

  • Patent number: 7123133
    Abstract: The present invention relates to a system for use in motorized vehicles to provide a vehicle back-up alarm system, intended for mounting on a vehicle, that also incorporates an apparatus for detecting and alarming low battery conditions. Preferably incorporated into a main housing are the electronic components that perform power regulation, system control, voltage sensing, timing, alarm tone generation, sound emitting and, optionally, light emitting. The housing serves to securely fix and retain these components and to protect them from moisture and dirt. The circuitry is connected to the vehicle upon which it is installed by preferably three connection terminals situated on the housing. Distinctive tones and/or lamp sequences alert the operator and those by-standers within proximity to the vehicle to different alarm conditions.

  • Patent number: 7115146
    Abstract: The present invention relates to an implant comprising two or more bone fragments that are combined to form a single unit. Cancellous bone or cortical bone is removed from a source and fashioned into bone components with desirable shapes and sizes. The bone components may be integrated to form implants for implantation in the body. Bone stock may be formed by combining sections of various bones of the body, and the bone stock may be further fashioned for use as implants with particular geometries.

  • Patent number: 6989011
    Abstract: The invention generally concerns a spine stabilization system having one or more flexible elements having an opening or slit. The flexible element may be integrally formed in a rod having ends capable of receiving fasteners. The flexible element may limit rotation, flexion-extension, or lateral bending of the spine. The slit or opening may form helical pattern on the rod, and more than one slit or opening may be provided. The flexible element may be conformable to the natural spinal movement.

  • Patent number: 6986788
    Abstract: An allogenic intervertebral implant for fusing vertebrae is disclosed. The implant is a piece of allogenic bone conforming in size and shape with a portion of an end plate of a vertebra. The implant has a wedge-shaped profile to restore disc height and the natural curvature of the spine. The top and bottom surfaces of the implant have a plurality of teeth to resist expulsion and provide initial stability. The implant according to the present invention provides initial stability need for fusion without stress shielding.

  • Patent number: 6986771
    Abstract: A spine stabilization system having one or more flexible elements with tubular structures with openings or slits. The flexible elements may limit rotation, flexion-extension, or lateral bending of the spine. The system also may have a locking mechanism that secures one or more flexible elements in a rigid configuration. A flexible element may be disposed within another flexible element, and the slits may form helical patterns on the tubular structures. The flexible element may be conformable to the natural spinal movement.

  • Patent number: 6929662
    Abstract: An end member for use with a bone fusion implant is disclosed. The end member has a first portion, a second portion, and a shoulder connecting the two portions. The second portion is sized to fit within the interior of the bone fusion implant in such a fashion that the shoulder rests on the edge of the implant. The top surface of the first portion has at least one slot to receive a surgical instrument such as an inserter and/or distractor to facilitate implantation of the end member and bone fusion implant. The top surface may also have teeth to provide initial mechanical stability between the bone and end plate and promote bone fusion.
