Patent CA-2237119-A1 (CA)
Inventor: RUSSELL THOMAS R
IPC: G01N33/53
Filed: 1996-11-05
Abstract: A separation procedure for separating a selected desired or undesired population from a biological sample utilizing relatively heavy, dense particles and gravity sedimentation. The particles (14) have one or more reactants bound thereto which are specific to and will bind with the selected population. The particles preferably are mixed with the sample (12) by repeatedly causing the particles to settle through a substantial portion of the sample to bind to the selected population. The particles with the bound selected population then are allowed to preferentially settle in the sample and the supernatant including an enriched population is separated from the particles with the selected population bound thereto. The enriched populations in the biological sample supernantant can be further enriched by multiple removal steps.

Abstract: An electric rotary shaver with one or a plurality of circular outer cutter unitseach formed with a plurality of blade formation regions of annular shapes concentrically arranged. The blade formation regions located outermost are formed greater in thickness than other blade formation regions(s), and hair-entry slitsextending in the radial direction are formed in the blade formation regions so as to form slit-form blades. Thus, the slit-form blades in the blade formation regions other the outermost blade formation region is thinner than those of the outermost blade formation region thus allowing deep shaving and assuring a strength of the outercutter unit..

Title: Magnetically suspended fluid pump and control system
Inventor: PREM EDWARD K
IPC: A61M60/892
Filed: 1998-10-23
Abstract: A blood pump for assisting a heart is provided having a stator and a rotor. The rotor is magnetically radially supported creating a suspension gap between the stator and the rotor. The rotor can be supported axially by a Lorentz force bearing and can be magnetically rotated. The stator can have a single or double volute pump chamber and the rotor can have an impeller portion for pumping blood. The rotor can have a center bore as a primary blood flowpath. The suspension gap can be a secondary blood flowpath. The blood pump can also have an axial position controller and a flow rate controller. The axial position controller can cause the axial bearing to adjust the position of the rotor. The flow rate controller can have a member for measuring a dimension of a heart ventricle to control the flow rate to avoid overly distending or contracting the ventricle. A method of operating the flow rate controller to create a pulsatile flow rate is also provided. Additionally, the blood pump can be part of a cardiac assist and arrhythmia control system. Moreover, a method of operating the flow rate controller can be provided which reduces the amount of energy needed to treat fibrillation. The method can include operating the flow rate controller to reduce a radial dimension of the ventricle prior to delivering defibrillation energy such that the ventricle contains less blood which absorbs less energy so that a larger fraction of the energy is delivered to the heart.

Patent CA-2265175-A1 (CA)
Title: A latching device for a circuit pack
Inventor: LOTZ WILLI MANFRED
IPC: H05K7/14
Filed: 1999-03-11
Abstract: A latching device is provided for a circuit pack having a cable retainer carried upon the front of the operating lever of the device. The cable retainer is oriented for positional and directional control of cable by directing cable longitudinally of the faceplate of the circuit pack and away from the fronts of other circuit packs within a shelf.      Also provided is a combination of a latching device and two groups of covers. The combination enables a single latching device to be used upon circuit packs requiring security and non security conditions within a shelf. It also enables removal of a faceplate held to a faceplate mounting with the circuit pack in the shelf. An orifice in an operating lever of the device is accessible with a cover of the first group mounted upon the operating lever, as orifices in these covers align themselves with the orifice in the operating lever. Where use of the operating lever orifice is not required, then a selected cover of the second group is mounted upon the operating lever and this cover, having no orifice, obscures the orifice in the operating lever. The covers are differentiated from one another by printed notation. This relates to the uses of different circuit packs. The covers may also include cable retainers provided with or without orifices.
Patent CA-2265832-A1 (CA)
Title: Automatic needle-passer suturing instrument
Inventor: KORTENBACH JUERGEN ANDREW
IPC: A61B17/04
Filed: 1997-09-23
Abstract: An automatic suturing instrument (10) generally includes a proximal actuation ha ndle assembly (12), a flexible tubular member (14), a control wire (18), and an end effector assembly (20). The control wire extends through the tubular member and the end effector assembly is coupled to the distal end of each of the tubular member and the control wire, while the handle (22) is coupled to the proximal end of each of the tubular member and the control wire. Actuation of the handle moves the co ntrol wire relative to the tubular member and thereby moves the end effector assembly (20) from an open to a closed position. The end effector assembly generally includes two end effectors (34a, 34b), a needle (36) engaged by one of the end effectors (but which can be engaged by either end effector alternately), and a suture material. The end effector assembly further includes a needle passing mechanism that automatically alternates which end effector engages the needle each time the end effectors are moved into a closed position.
Patent CA-2267267-A1 (CA)
Inventor: GREEN EDWARD
IPC: F02M25/07
Filed: 1997-08-22
Abstract: A low emission power generating apparatus which comprises a modified two-stroke diesel engine component (12) and modified turbocharger component (14) which has a relatively low aspect ratio. The diesel engine component (12) is a modification of a conventional two-stroke diesel engine design and includes an exhaust valve cam of unique design that has a cam profile which results in a later-than-normal exhaust valve (24) opening and an earlier-than-normal valve closing so that the time during which the exhaust valve (24) remains open is shorter than normal, thereby causing a substantially greater volume of residual gases to remain in the combustion chamber (18) following the scavenge stroke. Reduction in peak combustion temperature advantageously results in the lower than normal production of nitrogen oxide and, therefore, allows advancement of the injection timing, while still maintaining the NOx emissions coming form the engine lower than those legislatively mandated. The modified turbocharger component (14) provides an additional charge of oxygen-rich air into the combustion chamber (18).
Patent CA-2268379-A1 (CA)
Title: Inhibitor ligands directed against a receptor of vascular endothelial growth factor or against its coding sequence, as anti-angiogenics
Inventor: SIROIS MARTIN G
IPC: A61K31/70
Filed: 1999-04-21
Abstract: Vascular endothelial growth factor (VEGF) is a potent inducer of endothelial cell (EC) proliferation and migration in vitro, as well as inflammation in vivo. We showed recently that VEGF effect on vascular permeability was dependent on the synthesis of platelet-activating factor (PAF) by EC. Consequently, we sought to evaluate by antisense knockdown of gene expression the contribution of VEGF receptors (Flt-1 and Flk-1) on these events. VEGF (10-11 - 10-8M) elicited a dose-dependent increase of bovine aortic EC proliferation, migration and PAF synthesis by up to 2.05-, 1.31- and 35.9-fold above basal levels respectively. A treatment with two modified antisense oligomers (10-7- 5x10-7M) directed against Ftk-1 mRNA blocked by 100%, 91% and 85% the migration, proliferation and PAF synthesis mediated by VEGF  respectively. A treatment with two antisense oligomers directed against Flt-1 mRNA failed to modulate these activities. The use of placenta growth factor (10-8M), a Flt-1-specific agonist, induced only a slight increase (0.6-fold) of PAF synthesis. These data illustrate the crucial role of Flk-1 upon EC stimulation by VEGF. The capacity to inhibit the protein synthesis of Flt-1 and Flk-1 by antisense oligonucleotides provides a new approach to block VEGF pathological effects in vivo. Antagonists of VEGF  receptors, particularly the Flk-1 receptor, are contemplated as tools equivalent to the antisense molecules for their anti-angiogenic effect.
