  • Publication number: 20180318459
    Abstract: Sterilization apparatus comprising a sterilization instrument configured to be inserted through the instrument channel of a surgical scoping device and a withdrawal device for withdrawing the sterilization instrument from the instrument channel at a predetermined rate. The sterilization instrument comprises an elongate probe having a probe tip with a first electrode and a second electrode arranged to produce an electric field from received RF and/or microwave frequency EM energy. In operation the instrument may disinfect an inner surface of the instrument channel by emitting energy whilst being withdrawn through the channel.

  • Publication number: 20180280084
    Abstract: An electrosurgical vessel sealing device that can seal biological vessels using a confined microwave field that yields a well-defined seal location with low thermal margin. The device comprises a pair of jaws that are movable relative to each other to grip biological tissue. A blade for cutting the gripped tissue is slidable between the jaws. A coplanar microstrip antenna is mounted on the inner surface of one or both of the pair of jaws to emit microwave energy into the gap therebetween. The device may comprise a separate dissector element to enable fine tissue cutting and dissection to be performed.

  • Publication number: 20180268508
    Abstract: An example method to screen one or more individuals at a non-law enforcement facility includes generating a first request at an access point. The first request includes one or more identifying information for the one or more individuals. The access point is associated with, located at, and/or located near the non-law enforcement facility. The access point includes a first communication transceiver. The method also includes, with the first communication transceiver, transmitting the first request to at least one communication server that is not under law enforcement only control. The method also includes, with the first communication transceiver, receiving at least a portion of a local result of a search of at least one local database.

  • Publication number: 20170360497
    Abstract: Embodiments of the invention provide a hollow cable for transmitting radiofrequency and/or microwave frequency energy to an electrosurgical instrument, wherein the hollow cable is provided with electrical connectors for forming a bipolar electrical connection with an electrosurgical instrument that fits within, e.g. slides relative to, the hollow cable. The connectors can be conductive protrusions extending in an axial direction on opposite sides of the cable. The protrusions can be tabs, fins, rods, pins, or wires. The protrusions can be strips which engage corresponding terminals on the instrument. The transmission line structure of the invention can have a greater diameter than conventional coaxial cables, which can minimize loss whilst still providing access for control wires and/or fluid to reach a surgical instrument. The cable can be used with multiple instruments.

  • Publication number: 20170303986
    Abstract: Embodiments of the invention provide a hollow cable for conveying radiofrequency and/or microwave frequency energy to an electrosurgical instrument that can fit within, e.g. slide relative to, the hollow cable. The hollow cable provides a bipolar electrical connection to the electrosurgical instrument that is maintained when the electrosurgical instrument is rotated relative to the hollow cable. The cable may comprise a hollow coaxial transmission line having a rotatable component mounted at its distal end. The rotatable component comprises a longitudinal passageway continuous with the hollow coaxial transmission line. The rotatable component is rotatable relative to the transmission line and comprises a first and second conductive portions that are respectively electrically connected to first and second terminals on the coaxial transmission line and which are configured to maintain an electrical connection with their respective terminal when rotated relative to the coaxial transmission line.

  • Patent number: 7481145
    Abstract: A projectile, (Cruise Munition Detonator Projectile or CMDP), can be fired from a tank, modified grenade launcher or gun using a laser range finder, radar or manual input (dialer or keypad) range selector. The CMDP will prevent, neutralize and eliminate enemy close infighting. The CMDP can defend aircraft against SAM, shoulder launched missiles, and air-to-air missiles. The CMDP will travel a predetermined programmed distance and detonate in front of or behind, over or beside, or in the mist of a target. The CMDP allows small forces to strategically neutralize larger forces with devastating effect. The CMDP is a force multiplier and an anti-personnel weapon.
