The present invention discloses an orbital radio frequency melting catheter device capable of making quick linear radio frequency melting therapy in the chambers of heart. It is characterized by that it has a catheter body, its far-end is equipped with an electrode, and its near-end is connected with a locking device and a radio frequency cable. In the centre of the described catheter body a central hole coaxial with external edge of said catheter body is opened, in said central hole interior an elastic orbital guide wire is set, and the far-end of said elastic orbital guide wire is made into the form of ring. |
