  • Patent number: 8162935
    Abstract: Systems and methods are disclosed for assessing electrode-tissue contact for tissue ablation. An exemplary electrode contact sensing system comprises an electrode 10 housed within a distal portion of a catheter shaft 14. At least one electro-mechanical sensor 20 is operatively associated with the electrode 10 within the catheter shaft 14. The at least one electro-mechanical sensor 20 is responsive to movement of the electrode 10 by generating electrical signals corresponding to the amount of movement. The system may also include an output device electrically connected to the at least one electro-mechanical sensor 20. The output device receives the electrical signals for assessing a level of contact between the electrode 10 and a tissue 12.

  • Publication number: 20110160593
    Abstract: A three dimensional physiological mapping system utilizing an intracardiac echo catheter capable of being located in six degrees of freedom by a visualization, navigation, or mapping system. An echocardiography image of the intracardiac echo catheter may be projected within a geometric model of the visualization, navigation, or mapping system where the location of the projected image is adjusted in response to user input identifying a structure present in the echocardiography image and the geometric model.
