Abstract: A method for treating an affected portion in a heart comprises a catheter having a first end and a second end; a mono-polar or bi-polar electrode coupled to the first end, wherein the electrode is adapted to be inserted into heart tissue; a power source coupled to the second end and configured to energize the electrode, wherein the electrode emits a radio frequency (RF) signal upon being energized to heat the affected portion to a desired temperature; a temperature feedback control coupled to the electrode and the power source, wherein electrode is configured to alter the emitted RF signal based on a measured temperature of the affected portion. A rotatable member is configured to allow a first portion of the catheter to freely rotate with respect to a second portion of the catheter.
