  • Method for ablating with needle electrode
    Patent number: 9326813
    Abstract: A method for ablating tissue in or around the heart to create an enhanced lesion is provided. The distal end of a catheter including a needle electrode at its distal end is introduced into the heart. The distal end of the needle electrode is introduced into the tissue. An electrically-conductive fluid is infused through the needle electrode and into the tissue. The tissue is ablated after and/or during introduction of the fluid into the tissue. The fluid conducts ablation energy within the tissue to create a larger lesion than would be created without the introduction of the fluid.
    Type: Grant
    Filed: April 24, 2007
    Date of Patent: May 3, 2016
    Assignees: Biosense Webster, Inc., The Brigham & Women's Hospital, Inc.
