  • Publication number: 20170014185
    Abstract: An improved antenna for microwave ablation uses a triaxial design which reduces reflected energy allowing higher power ablation and/or a smaller diameter feeder line to the antenna.
    Type: Application
    Filed: July 15, 2016
    Publication date: January 19, 2017
    Applicant: NeuWave Medical, Inc.

  • Patent number: 7520877
    Abstract: Efficient ablation with multiple prong electrodes is obtained by electrically isolating the prongs from each other and rapidly switching electric power between the prongs, between a prong and a ground pad, or both. In this way, power distribution to a tumor can be controlled efficiently without the need to change probe geometry.

  • Publication number: 20070055224
    Abstract: A microwave device that can be used to effectively treat esophageal pathologies comprises a coaxial, triaxial or quadraxial microwave antenna housed in an esophageal dilator or balloon. The device can be introduced into the esophagus alongside or through an endoscope, and will deliver microwave energy to tissue. This energy heats the affected tissue, which subsequently undergoes necrosis thereby eliminating the potential of the tissue to undergo malignant transformation. The dilator or balloon is used to keep the antenna in the center of the lumen allowing for symmetrical heating of the esophagus. The depth of penetration of the coagulation effect can be varied depending on the amount of power that is applied, the location of the antenna relative to the tissue, and the duration of the power application.

  • Publication number: 20070049919
    Abstract: A radiofrequency ablation system provides multiple ground pads and active control of current flow through the ground pads to provide improved power sharing at the tissue near the ground pads reducing risk of patient skin burns for higher power ablation generators.
