  • Publication number: 20190380778
    Abstract: An electrosurgical apparatus for treating fluid-filled biological growths by replacing the fluid within the growth with a substance that assists in delivering treatment energy. The treatment energy may be microwave energy or may be thermal energy derived from microwave energy. The apparatus comprises an instrument having a radiating tip portion, and a fluid delivery mechanism for transporting fluid to and from a treatment zone located around the radiating tip portion. The fluid delivery mechanism comprises a rigid insertion element arranged to extend into the treatment zone, whereby fluid can be aspirated from the treatment zone, and a substance injected into the treatment zone to replace the aspirated fluid. The injected substance has dielectric properties selected to facilitate uniform delivery of treatment energy to biological tissue in the treatment zone.

  • Publication number: 20190379540
    Abstract: Aspects of secure inter-application data communications are described. In one example, a first application executing on a computing device obtains an identity certificate. The identity certificate can include a unique identifier of the computing device and a public key of the first application. To obtain the public keys of other applications executing on the computing device, the first application can query a management computing environment using the identity certificate. Once the computing device is authenticated by the management computing environment, the management computing environment can store the public key of the first application and return any public keys of other applications executing on the computing device. Once the public keys have been exchanged between the applications, the applications can encrypt and sign data packages for secure data communications between each other.

  • Patent number: 10434207
    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 while being withdrawn through the channel.

  • Publication number: 20190167077
    Abstract: A movement transfer mechanism for a surgical scoping device, wherein a rotational proximal input force is transformed into a longitudinal force that is conveyed down the length of an instrument channel of the scoping device, where it is transformed again into an operational movement of a distal instrument. The operational movement can be rotational movement, but may be any movement that changes the orientation or configuration of the distal instrument. By conveying a linear force along the instrument channel rather than a twisting force, the problems of slipping and discontinuous operation of the distal instrument due to friction between the instrument and the instrument channel can be reduced or eliminated.

  • Publication number: 20190110837
    Abstract: An electrosurgical apparatus and method for performing thermal treatment in the gastrointestinal tract, e.g. to ablate duodenal mucosal tissue. The apparatus comprises an instrument having a flexible cable and an applicator suitable for use with a gastroscope, which can be deployed within a patient to delivery energy in a targeted or otherwise controllable manner. The applicator can deliver microwave energy by radiation. The direct and depth-limited nature of microwave energy can be make it more effective than treatments that rely on thermal conduction. The applicator may include a radially extendable portion arranged to move an microwave energy delivery structure into contact with duodenal mucosal tissue at the treatment region. The applicator may comprise any of a balloon, bipolar radiator, movable paddle, and rotatable roller element.

  • Publication number: 20190099215
    Abstract: An electrosurgical cutting tool comprising a pair of pivotable blades that are mechanically operable as scissors or pliers. The blades have electrodes capable of delivery RF and/or microwave energy to cut or coagulate tissue between them. The tool combines the actuation and energy delivery mechanisms in a compact arrangement that enables the tool to be inserted through an instrument channel of a surgical scoping device, such as an endoscope, gastroscope or laparoscope. Each blade may comprise a planar body made of dielectric material that separates a first conductive element from a second conductive element. The blades may rotate relative to each other in the plane of the blades.

  • 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: 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.

  • 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.
