Title: Articulating ionizable gas coagulator
Inventor: PLATT ROBERT
IPC: A61B18/14
Filed: 2000-09-25
Abstract: An electrosurgical apparatus for coagulating tissue includes an elongated flexible tube having a proximal end, a distal end and a source for supplying pressurized ionizable gas to the proximal end of the tube. The apparatus also includes a hollow sleeve made from a shape memory alloy having a generally curved austenite state and displaying stress-induced martensite behavior. The hollow sleeve is restrained in a deformed stress-induced martensite configuration within the tube and partial extension of a portion of the hollow sleeve from the tube transforms the portion of the sleeve from the deformed configuration to the generally curved austenite configuration such that the gas is directed transversely at the tissue. An electrode ionizes the gas in the region between the sleeve and the tissue. Other embodiments of the present disclosure also include a wire connected to the distal end of the tube which movable from a first position wherein the tube is disposed in a generally rectilinear, parallel fashion relative to the tissue to a second retracted position wherein the distal end of the tube flexes at an angle to direct the gas towards the tissue. Still other embodiments of the present disclosure include a corona electrode for inducing ignition of the gas.

Title: Method and apparatus for a wireless telecommunications system that provides location-based information delivery to a wireless mobile unit
Inventor: RICHTON ROBERT ELLIS
IPC: H04W4/029
Filed: 2000-11-01
Abstract: A wireless telecommunications system uses location or position information of a wireless mobile unit to initiate the sending of location-specific information to travelers. As position information is received, it is compared to prestored position information of a remote location, such as an airport. As the traveler approaches the remote location, and gets within a certain distance the remote location, information such as airline arrival information is retrieved and sent to the wireless mobile unit of the traveler. Thus, useful information tied to the position of the wireless mobile unit, such as airline or traffic information for example, is obtained.

Patent CA-2331772-A1 (CA)
Title: Hemoglobins to maintain cell energy status
Inventor: SOWA ALEKSANDER
IPC: A61K35/12
Filed: 1999-06-24
Abstract: Nonsymbiotic hemoglobins are broadly present across evolution; however, the function of these proteins is unknown. Cultured maize cells have been transformed to constitutively express a barley hemoglobin gene in either the sense (HB+) or antisense (HB-) orientation.  Hemoglobin protein in the transformed cell lines was correspondingly higher or lower than in wild type cells under normal atmospheric conditions. Limiting oxygen availability, by placing the cells in a nitrogen atmosphere for 12 hours, had little effect on the energy status of cells constitutively expressing hemoglobin, but had a pronounced effect on both wild type and HB- cells, where ATP levels declined by 27 % and 61 % respectively. Energy charge was relatively unaffected by the treatment in HB+ and wild type cells, but was reduced from 0.91 to 0.73 in HB- cells suggesting that the latter were incapable of maintaining their energy status under the low oxygen regime. Similar results were observed with P. aeruginosa cells transformed with an Hb expression vector. It is suggested that nonsymbiotic hemoglobins act to maintain the energy status of cells in low oxygen environments and that they accomplish this effect by promoting glycolytic flux through NADH oxidation, resulting in increased substrate level phosphorylation. Nonsymbiotic hemoglobins are likely ancestors of an early form of hemoglobin that sequestered oxygen in low oxygen environments, providing a source of oxygen to oxidize NADH to provide ATP  for cell growth and development. This in turn suggests that cells containing increased levels of Hb protein will survive longer under low oxygen tension or high energy demand.

Abstract: According to the 3D-CAD system of the present invention, basic graphic elements (PL, LL, SL, VL) are set based on linear, area or volume coordinate parameters, and the plurality of basic graphic elements are continuously connected to generate a basic graphic. The basic graphic elements constituting the generated basic graphic are continuously differentiable even after deformation, thereby generating a desired solid graphic (identical topology graphic). By using these patches for approximately expressing all surfaces, the surfaces are handled consistently, the data quantity describing the graphics is greatly reduced, and the load of operational processing of the computer is reduced. Whether or not an element can be deleted is determined based on a reference counter RC showing whether said element is the component of another element.

Title: Inherently antimicrobial quaternary amine hydrogel wound dressings
Inventor: ROUNS CAMERON G
IPC: H01B1/12
Filed: 1999-08-30
Abstract: A composition and method for treating a wound with an inherently antimicrobial dressing. The dressing is a hydrogel containing from about 15 to 95 percent, and preferably from about 61 to 90 percent, by weight of a cationic quaternary amine acrylate polymer prepared by the polymerization of acryloyloxyethyl(or propyl)-trialkyl(or aryl)-substituted ammonium salts or acrylamidoethyl(or propyl)-trialkyl(or aryl)-substituted ammonium salts. The antimicrobial hydrogels are non-irritating to the wound, absorb wound exudate, and, due to the inherently antimicrobial properties, enhance the sterile environment around the wound. The hydrogels have sufficient adhesive properties that loose contact with the wound is assured but can also be removed without leaving any gel residue on the wound. The wound dressings are preferably formed on a substrate, such as a web or patch, for ease in application to and removal from the wound. If desired, additional antimicrobial or other pharmaceutically active agents can also be incorporated into the hydrogel structure.
