  • RADIO FREQUENCY SURGICAL INSTRUMENTS
    Publication number: 20200268431
    Abstract: The present invention relates to electrode arrays that find use for rapid ablation of a target area of tissue in an organ and in particular to use of the electrode arrays to resect organs to coagulate tissue so that resection can be performed with minimal loss of blood. The target area may include a bulk area of tissue (such as a tumor) or organ (such as a kidney) or a defined target area within a tissue or organ (such as a linear strip, curved strip, cylindrical area, or other shape).

  • Target pedestal assembly and method of preserving the target
    Patent number: 7835502
    Abstract: An x-ray target pedestal assembly and a method of protecting the x-ray target from breaking down as a result of the extreme heat that is produced when an electron beam is aimed at the target to produce x-rays. The target is submerged in cooling fluid and is rotated by a constant flow of the cooling fluid over and around the target in order to dissipate heat. The fluid is guided by integrated flow diverters in the target cover. The target may also be protectively coated either in its entirety or along the electron beam path in order to further protect it from the heat of the electron beam impact or from breakdown as a result of attack of free radicals or other chemically reactive components of the cooling fluid which are produced in the extreme target environment.
