    Abstract: A method for mapping includes receiving electrical inputs measured by a probe at respective locations in a chamber of a heart of a subject. The electrical inputs are processed to identify complex fractionated electrograms. At each of the respective locations, a respective contact quality between the probe and a tissue in the chamber is measured. A map of the complex fractionated electrograms in the chamber is created using the electrical inputs and the measured contact quality.

    Abstract: A position sensing system includes a probe adapted to be introduced into a body cavity of a subject. The lasso-shaped probe includes a magnetic field transducer in the rigid section proximal to the flexible lasso-shaped distal section which has at least one probe electrode. A control unit is configured to measure position coordinates of the probe using the magnetic field transducer. The control unit also measures an impedance between the at least one probe electrodes and one or more points on a body surface of the subject. Using the measured position coordinates, the control unit calibrates the measured impedance and provides an indication of the deformation and deflection of the flexible lasso-shaped distal section in relation to the magnetic field transducer in the rigid proximal section.

    Abstract: A device for enhancing visualization of an esophagus when imaged by a visualization system includes a structure including material that is clearly visible when imaged by the visualization system. The structure is arranged, when inserted into the esophagus, to expand so as to conform to an inner surface of the esophagus in order to enhance a visualization quality of the surface when imaged by the visualization system. A cord attached to the structure is arranged to extend out of the esophagus so as to assist a removal of the device from the esophagus.

    Abstract: A resonant circuit is incorporated in a stent, which implantable in a pulmonary vein using known cardiac catheterization techniques. When an external RF field is generated at the resonant frequency of the stent, RF energy is re-radiated by the stent toward electroconductive tissue in the wall of the pulmonary vein, and produces a circumferential conduction block. The stent can be made of biodegradable materials, so that it eventually is resorbed. Following an ablation procedure, the stent may be left in situ. Repeated ablation can be performed using the inserted stent until it has been determined that the desired lesions have been formed. Furthermore, the same stent can potentially be used even years after being inserted should the treated arrhythmia reoccur or a new arrhythmia develop, thereby possibly obviating the need for an invasive procedure at that future time.
