  • Patent number: 6314996
    Abstract: A foam marking system is provided with separate tanks for water and foam concentrate. A water pump and a concentrate pump deliver water and concentrate from the respective tanks to a mixing chamber at a pre-selected ratio. The water pump is controlled by a master control, while the concentrate pump is controlled by a slave control depending from the master control. The master control generates and output signal which is sent to both the water pump and the slave control, such that the slave control and concentrate pump operate as a function of the master control and water pump, so that the selected mix ratio can be maintained, regardless of the output level of the foam from the system. A foam generation chamber connected to the mixing chamber and to an air source generates foam when the foam solution is mixed with air.

  • Patent number: 6315777
    Abstract: A method and apparatus for creating a virtual electrode to ablate bodily tissue. The surgical apparatus includes an inner tube and an outer tube. The inner tube defines a proximal portion and a distal portion. The distal portion forms an orifice for distributing a conductive solution from the inner tube and further forms an electrode. The outer tube coaxially receives the inner tube such that the outer tube is slidable relative to the inner tube. With this configuration, the outer tube selectively blocks flow of conductive solution from the orifice. During use, conductive solution distributed from the orifice is subjected to a current from the electrode, thereby creating a virtual electrode.

  • Patent number: 6317354
    Abstract: A non-volatile RAM device is disclosed which utilizes a plurality of ferromagnetic bits (6) each surrounded by a coil of a write line (13) for directing the remnant polarity thereof is disclosed. The direction of magnetic remnance in each bit (6) is dictated by the direction of a current induced into write line (13). Further, a magneto sensor (7) comprising a magneto resistor (1) coupled to a collector (2) is placed approximate each bit (6). The magneto resistor (1) is coupled to a control circuit (30) for receiving current. The current passing across magneto resistor (1) is biased in a direction either right or left of the original current flow direction. The collector is coupled to a sense line (4), which in turn, is coupled to an amplifier (12). When current flow is biased in the direction of the collector, the serial resistance of the magneto resistor will be decreased, and the sense line (4) will receive a high amount of current.

  • Publication number: 20010039410
    Abstract: A method and kit for accessing the pericardial space take advantage of the fact that the right auricle is a thin-walled, low-pressure structure which can be readily penetrated without damaging the pericardium or the epicardium. The method includes the step of passing a guide catheter through a selected peripheral vein to establish a transvenous route to the right auricle of the heart. An infusion guide wire and a leading guide wire are passed through the guide catheter and into the right auricle so that a distal end of the leading guide wire is positioned against a wall of the right auricle. The leading guide wire is located within a lumen of the infusion guide wire and protrudes outward, preferably about 2 mm, from a distal end of the infusion guide wire. The wall of the right auricle is then pierced with the distal end of the leading guide wire. After the wall of the right auricle is pierced, at least one of the infusion guide wire and the leading guide wire are advanced into the pericardial space.
