  • ABLATION CATHETER
    Publication number: 20140288552
    Abstract: Devices, systems and methods are disclosed for the mapping of electrical signals and the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be transformed from a compact, linear configuration to a helical configuration, such as to map and ablate pulmonary vein ostia.

  • USER INTERFACE FOR TISSUE ABLATION SYSTEM
    Publication number: 20140171942
    Abstract: Devices, systems and methods are disclosed for the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be constrained within the lumen of a catheter, and deployed to take on an expanded condition. The carrier assembly includes multiple electrodes that are configured to ablate tissue at low power. Systems include an interface unit with a visual display that provides a visual representation of the geometry of the ablation elements and/or provides selection means for selecting an icon provided on the display.
