  • Publication number: 20080077083
    Abstract: An automatic injector separately stores liquid and dry components in respective compartments. When the injector is activated, a fluid-directing member between the liquid and dry compartments causes the liquid component to form a vortex as the liquid flows into the dry compartment. This allows the two components to combine more thoroughly and quickly to form a liquid solution that is delivered to an injection site.

  • Publication number: 20070142768
    Abstract: An automatic medicament injector having a compartment for a dry medicament component and a compartment for a wet medicament component. The two compartments are separated by a seal structure that converts from a sealing condition into a mixing condition when the device is activated. The seal structure includes a wiper that scrapes the interior walls in the dry component compartment to prevent the dry component from accumulating at the seal/glass interface. A tapered insert funnels the mixed medicament components to an attached needle assembly, but can be removed when the device is filled. A filter is provided between the medicament compartments and the needle assembly. A chamber between the filter and the needle allows for better flow through the filter. An actuation assembly drives the seal structure into the mixing condition and forces the mixed medicament through the needle and into the user.

  • Publication number: 20070055236
    Abstract: The present invention is an apparatus and method for stabilizing the facet joints of the spine. One aspect of the present invention is the stabilization of the facet joint by insertion of a facet implant through two opposing facet surfaces. The facet joint is not fixedly frozen by insertion of the screw, but instead the facet surfaces are flexibly and movably anchored to preserve movement because the screw or anchor includes a flexible intermediate portion which is positioned between the facet surfaces. The facet implant may be in the form of a screw or other anchor with the intermediate portion in the form of a polyaxial head, a cord, a spring, etc. The facet implant may furthermore be used in conjunction with a facet spacer that is placed between the first and second facet.

  • Publication number: 20070041988
    Abstract: The present invention provides the use of nucleic acid sequences and/or amino acid sequences in the preparation of a vaccine for the protection of fish against infectious salmon anaemia virus. Specifically, such vaccines contain at least one nucleic acid sequence which is derived from ISAV or synthetically prepared analogues thereof, or substantially homologous sequences. These nucleic acid sequences are transcripted and translated into peptide sequences which are incorporated into a vaccination strategy to induce and immune response to the surface antigens of ISAV and therefore ISAV itself. Therefore both the use of a vaccine against ISAV, and the incorporation of peptide sequences is herein described.

  • Publication number: 20060127416
    Abstract: The hsp60 gene from a strain of Arthrobacter has been isolated and sequenced. The encoded protein is believed to be highly immunogenic, especially in fish, and also has utility as a non-specific adjuvant, and as an adjuvanting carrier for heterologous antigens.

  • Publication number: 20050236102
    Abstract: The present invention relates to compositions and methods for creating insulating seals for use in a variety of applications, and to seals created by such compositions and methods. In particular, the present invention provides novel compositions and methods for creating insulating edge seals that provide multiple contact surfaces. The present invention further provides seals that facilitate attachment of flexible covering materials (such as fabrics, plastics, metals, etc.) to hard surfaces (such as plastics, metals, woods, etc.). The present invention is particularly useful for creating insulating edge seals that provide a means of attachment for removable covers for vehicles (such as tops for automobiles, watercraft, and aircraft), structures, and objects.

  • Patent number: 6770052
    Abstract: The present invention is directed to an automatic injection device containing a pre-loaded charge of medicament for automatically self-administering the medicament upon actuation thereof. The automatic injection device includes a housing assembly having an interior chamber, a filter assembly, an activation assembly and a needle assembly. In accordance with the present invention, the interior chamber may include a dry compartment for storing a predetermined dry charge of dry medicament therein, and a wet compartment for storing a predetermined amount of liquid injection solution therein. The filter assembly enhances the laminar flow of fluid between the wet compartment to the dry compartment prior to the pressurization of the liquid injection solution within the wet compartment.

  • Publication number: 20040097874
    Abstract: A separation assembly for a container for separating a first component from a second component is disclosed. The separation assembly includes a generally cylindrical body that is constructed and arranged to be slidably supported within a container between a liquid component and a dry component. The body includes a seal structure constructed and arranged within the container between the first component and the second component. The seal structure has an inner seal member wherein the inner seal member is initially in a sealing condition that maintains the first component sealed from the second component. The inner seal member being converted to a mixing condition in response to the predetermined operating condition such that the first component flows through at least one flow path in the seal structure to mix with the second component.

  • Patent number: 6641561
    Abstract: The present invention is directed to a drug delivery device. The device includes an interior chamber and a seal structure. In accordance with the present invention, the interior chamber may include a first, liquid medicament compartment and a second medicament compartment. The seal structure is conditionable to permit fluid to pass therethrough upon pressurization of the fluid. The seal structure preferably includes a sealing member which moves from a first sealed position into a second by-pass position upon pressurization of the liquid injection solution in the wet compartment of the housing assembly. Such by-pass movement of the sealing member enables the liquid injection solution to flow through the seal structure into the second ingredient compartment and mix for injection.
