Patent CA-2233040-A1 (CA)
Title: Transgenic animals for xenotransplantation with reduced antibody-mediated rejection
Inventor: SHARMA AJAY
IPC: A61P37/06
Filed: 1996-09-23
Abstract: A method of xenotransplanting organs, tissues, cells or non-viable components which reduces or prevents antibody-mediated rejections, including hyperacute rejection, is provided wherein transgenic animals are produced that express at least one enzyme which masks or reduces the level of the antigenic Gal.alpha.(1,3)Gal or gal epitope, and at least one complement inhibitor such as CD59, DAF and/or MCP. The transgenic animals which express both a gal epitope-reducing enzyme and a complement inhibitor will have masked or reduced levels of the gal epitope and will be much less likely to produce an antibody-mediated rejection following transplantation, and the expression of the complement inhibitor will also suppress complement activation and reduce even further a severe immune reaction following the transplantation of donor organs, tissue, cells or non-viable components from the transgenic animals so produced. In addition, transgenic animals are provided which express a plurality of complement inhibitors or other proteins from a locus of genes at a single integration site. The present invention is thus advantageous in that it can provide xenogeneic organs, tissues, cells and non-viable components which can be transplanted safely and effectively into humans with a reduction or elimination of antibody-mediated rejection to an extent not previously possible, and which will significantly reduce the need to obtain donor organs, tissues, cells or non-viable components from human or primate donors.

Filed: 1998-06-23
Abstract: A suture cartridge assembly is disclosed. The assembly has a suture cartridge containing a slot for receiving a suture filament and a cartridge top for covering at least a portion of the filament. A grasping jaw faces the cartridge top, and it is movable from an open position spaced from the cartridge top to a closed position adjacent the cartridge top. The slot in the cartridge for receiving the filament facilitates the formation and placement of surgical knots made from the suture filament, particularly when knots are needed at remote surgical sites such as during minimally invasive surgery. The placement and deployment of the knot is further facilitated because the grasping jaw can grasp the filament or the tissue which is desired to be sutured when the jaw is moved from its open to closed positions. The ability to grasp the filament or tissue enables the surgeon to manipulate the filament or tissue during the procedure for deploying and placing the knot, further facilitating the ease with which the surgeon can deploy and place the knots in a minimally invasive procedure.

IPC: H04B10/508
Filed: 1997-02-14
Abstract: A receiver at a node in an optical network receives an optical clock signal and a OTDM datastream. A detector converts the clock signal to the electrical domain. A variable delay stage applies a selected delay to the clock signal in the electrical domain. A non-linear electro-optic modulator which may be an electro-absorption modulator, receives the OTDM datastream at its optical input. An electrical control input of the modulator is connected to the output of the variable delay stage. The electro-optic modulator outputs an OTDM  channel selected by setting the delay of the variable delay stage. The variable delay stage may comprise a number of logic gates, particularly AND  gates, connected between a pair of microstrip delay lines. The gates are controlled to provide different paths with different corresponding delay times for the clock signal.

Patent CA-2256200-A1 (CA)
Inventor: BOULOS JOHN
IPC: H01Q1/12
Filed: 1998-12-16
Abstract: A major problem with current satellite dish installations is that wind has a tendency to cause the satellite dish to come out of alignment with the satellite. This results in bad image reception or, in most cases, failure of the dish to receiveinformation from the satellite. Once misaligned, the satellite has to be re-focused by a technician skilled in satellite dish installation. The invention is a digital satellite dish stabilizer that eliminates the effects of wind and other elements on dish alignment with a satellite in geosynchronous orbit. The satellite dish stabilizer consists of a steel rod which connects the satellite dish to the mounting surface through the use of a surface mounting flange and a dish connection unit. The surface mounting flange is attached to the mounting surface via mounting screws. The dish connection unit is attached to the satellite dish. A steel rod connects the surface mounting flange to the dish connection unit. The surface mounting flange, dish connection unit and steel rod are attached in series and form the stabilizer for the satellite dish. There is preferably a satellite dish stabilizer supporting each side of the satellite dish, i.e. there is a surface mounting flange, dish connection unit and steel rod on both sides of the satellite dish.
