Patent CA-2453568-A1 (CA)
Inventor: RIOUX ROBERT F
IPC: A61B18/12
Filed: 2002-08-30
Abstract: L'invention concerne des dispositifs d'occlusion d'un vaisseau au cours d'une procédure d'ablation percutanée. Un dispositif d'accès allongé comprenant une lumière et une extrémité distale ouverte en communication avec la lumière est utilisé pour accéder par voie percutanée à un vaisseau délivrant du sang au tissu destiné à être traité. Un dispositif allongé de déploiement du ballonnet est utilisé pour mettre en place un ballonnet à l'intérieur du vaisseau. Le ballonnet est ensuite gonflé, permettant l'occlusion du vaisseau. Le tissu à traiter est alors soumis à une ablation. En raison de la faible quantité ou de l'absence de sang pour transférer l'énergie thermique du tissu chauffé, la procédure d'ablation est réalisée plus efficacement. Le ballonnet peut ensuite être dégonflé, permettant le retour d'un flux normal dans le vaisseau.

Title: Genetically biotinylated recombinant antibody in immunofiltration assay by light addressable potentiometric sensor for identification of venezuelan equine encephalitis virus
Inventor: HU WEIGANG
IPC: G01N33/543
Filed: 2004-03-24
Abstract: A genetically biotinylated single chain fragment variable (scFv) antibody against Venezuelan equine encephalitis virus (VEE) being applied in a system consisting of an immunofiltration-enzyme assay (IFA) with a light addressable potentiometric sensor (LAPS) for the rapid identification of VEE is disclosed. The IFA entails formation of an immunocomplex sandwich consisting of VEE, biotinylated antibody, fluoresceinated antibody and streptavidin, capturing the sandwich by filtration on biotinylated membrane, and detecting the sandwich by anti-fluorescein urease conjugate. The concentration ratio of biotinylated to fluoresceinated antibodies is investigated and optimized.  The IFA/LAPS assay sensitivity was approximately equal to that of a conventional enzyme-linked immunosorbant assay utilizing polystyrene plates and a chromogenic substrate, however, less time and effort were required for performance of the IFA/LAPS  assay.

Patent CA-2463749-A1 (CA)
Inventor: SPRIENSMA BRENT S
IPC: F04B35/01
Filed: 2004-04-13
Abstract: The invention contained herein is a mechanical device capable of, among other things, fluid compression and/or displacement, and can be used for any of the applications traditionally associated therewith. The device is comprised of a block housing with radially mounted chambers. The housing contains a central crank mechanism and fixed near the crank mechanism's circumference is a rotor that terminates in two specially shaped heads. A  driver is then attached to the crank mechanism's axle and the rotor's axle is geared so as to counter-rotate the rotor one revolution for each revolution of the central crank mechanism. The sum of the two rotations creates a linear compression or displacement stroke, with rotor heads alternating between diametrically opposed chambers. Intake is directed into the block housing and output (controlled by unidirectional valves) is at the anterior end of each chamber.
