  • Publication number: 20060086254
    Abstract: A filter assembly for use in sidestream gas sampling assembly. The filter assembly of the present invention includes a hydrophilic The filter further includes a hydrophobic member positioned downstream of the hydrophilic liner. The hydrophobic disk acts as a second line of defense against moisture reaching the sensing mechanism member that is constructed from a porous material and is situated such that gas entering the filter assembly passes through at least a portion the hydrophilic member. In a further embodiment, the filter includes a hydrophobic member positioned downstream of the hydrophilic member. The hydrophobic member acts as a second line of defense against moisture reaching the sensing mechanism in the gas sampling assembly.

  • Patent number: 7022672
    Abstract: A method of modifying protein solubility employs polyionic polymers. These facilitate the solubilization, formulation, purification and refolding of proteins especially incorrectly folded proteins and aggregated proteins. Compositions are described that are suitable for formulating TFPI. The compositions allow preparation of pharmaceutically acceptable compositions of TFPI at concentrations above 0.2 mg/mL and above 10 mg/mL.

  • Publication number: 20060036763
    Abstract: A system and method of routing requests received from client computers. The client computer processor is redirected to a router for which the address is within the preferred coverage zone. If a router is not identified for which the address is within a preferred coverage zone, but a router other than the router that received the request is identified for which the address is within a regular coverage zone, the processor is redirected to the router for which the address is within the regular coverage zone. If a message is transmitted from a router behind a firewall to a router outside the firewall, and then a request for data is received from a processor behind the firewall, the processor is redirected to the address of the router. Routers register themselves dynamically into a hierarchy. In another alternative embodiment, a service request from a particular client computer is serviced immediately by the root router rather than redirected to another router.

  • Publication number: 20050282771
    Abstract: Methods for treating bleeding disorders using non-anticoagulant sulfated polysaccharides (NASPs) as procoagulants are disclosed. NASPs can be administered as single agents, or in combination with one another, or with other medications (such as factors VII, VIII and IX) to promote hemostasis. In particular, the use of NASPs in treatment of bleeding disorders, including congenital coagulation disorders, acquired coagulation disorders, and trauma induced hemorrhagic conditions is described.

  • Patent number: 6933111
    Abstract: This invention pertains to plants, plant material and seeds characterized by harboring a specific transformation event particularly by the presence of the bar gene under control of a CaMV 35S promoter, at a specific location in the rice genome. The rice plants of the invention combine glufosinate tolerance with optimal overall agronomic performance, genetic stability and adaptability to different genetic backgrounds.

  • Publication number: 20050173841
    Abstract: A system and method for vacuum bag assembly fabrication via the vacuum bag method which reduces the amount of trapped air. The inventive system includes a chamber adapted to contain a vacuum bag and first and second evacuating mechanisms. The first evacuating mechanism serves to evacuate the bag and vent to atmosphere. The second evacuating mechanism serves to evacuate and vent the chamber to atmosphere. Thus, generally, the inventive method includes the steps of placing a vacuum bag lay up in an air tight chamber; and evacuating the vacuum bag lay up and the air tight chamber at the same time. In practice, the assembly would consist of at least two components and a heat curable composition. The components can be parts to be bonded together or layers of cloth to be made into a laminate. In this case, the heat curable composition would be a catalyzed adhesive or resin.

  • Patent number: 6656203
    Abstract: A integral vascular filter system comprising a guidewire and an integral filter which can be used to capture embolic particulates during medical procedures, while allowing for continuous perfusion of blood, with minimal incremental blood flow turbulence. The vascular filter system addresses the clinical problem of minimizing profile or diameter, so as to enable or facilitate the crossing of a lesion or obstruction in the vessel, while also minimizing incremental blood flow turbulence which may result in thrombus formation.

  • Patent number: 6596011
    Abstract: An emboli extraction catheter and vascular filter system comprising a guidewire, a vascular filter attached near the distal end of the guidewire, and an emboli extraction catheter. The vascular filter has a smaller first diameter for insertion into the lumen of a vessel, and a second larger diameter for expanding to substantially equal the diameter of the lumen and to be placed in generally sealing relationship with the lumen. The emboli extraction catheter is a flexible catheter comprising a hub attached to the proximal end of the catheter. The hub further comprises a sideport and means for maintaining a seal on the guidewire. The emboli extraction catheter can be used to aspirate embolic particulates, so as to avoid their accidental release after they are captured in a vascular filter, and can also be used to empty full vascular filters of embolic particulates which may block distal flow.
