  • Patent number: 9226788
    Abstract: Described herein is a method for creating a channel through a foreign material located in a body of a patient. The foreign material defines a material first surface and a substantially opposed material second surface and the channel extends through the foreign material between the material first and second surfaces. The method uses an apparatus including an electrode, and includes the steps of: positioning the electrode substantially adjacent to the material first surface; energizing the electrode with a radiofrequency current; and using the electrode energized with the radiofrequency current to deliver energy into the foreign material to create the channel. In some embodiments, the patient's body includes a heart defining a septum, the septum defines an aperture extending there-through and the foreign material extends across the aperture to cover the aperture.

  • Patent number: 9078663
    Abstract: An electrosurgical device for devitalizing tissue including a probe body, equipped with at least one electrode, and a cooling device. The probe body is suitable for generating a heat distribution field by means of a high-frequency current for devitalizing the tissue. The cooling device prevents carbonization of the tissue close to the probe body that would normally occur since the maximum current density occurs here. The electrosurgical device is modified such that the heat distribution over the probe body can be adjusted, allowing adjustment or positioning of a maximum cooling zone within the probe body. This regulation may be accomplished by regulating the inlet pressure of the refrigerant supply to the electrosurgical device.
