Abstract
A method for creating a channel through a foreign material located in a body of a patient, the foreign material defining a material first surface and a substantially opposed material second surface, the channel extending through the foreign material between the material first and second surfaces, the method using an apparatus including a substantially elongated member defining a proximal end region and a substantially longitudinally opposed distal end region, the apparatus including an electrode located about the distal end region, the method comprising: introducing the distal end region into the body of the patient; 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.
