Note: Text based on automatic Optical Character Recognition processes. Please use the PDF version for legal matters
CLAIMS:
1. A device for making linear lesions into tissue, comprising a probe having a distal end and a proximal end, the probe having an RF electrode at the distal end, the probe further having means for coupling the RF electrode to an RF power source, the probe further having a handle at the proximal end and a shaft extending from the handle to the RF electrode, wherein the RF electrode comprises a spherical ball rotatably mounted to the shaft.
2. A device according to claim 1 in which the handle is made of a sterilizable material.
3. A device according to claim 2 in which the handle is made of a rigid material.
4. A device according to claim 3 in which the handle is made of a non-conductive material.
5. A device according to claim 1 in which the shaft is a hollow cylindrical tube.
6. A device according to claim 5 in which the shaft is rigid.
7. A device according to claim 6 in which the rigid shaft is constructed of metal.
8. A device according to claim 2 in which the RF electrode has a temperature sensor for sensing the temperature of the RF electrode, the probe having means for coupling the temperature sensor to the RF power source.
9. A device according to claim 8 further comprising means for adjusting the RF energy delivered to the RF electrode based on at least the sensed temperature.
10. A device according to claim 9 in which the device further comprises means for delivering electrically conductive fluid from a lumen adjacent the RF electrode.
11. A device according to claim 10 in which the device further comprises means for delivering temperature-treated, electrically conductive fluid from a lumen adjacent the RF electrode.
12. A device according to claim 11 in which the temperature-treated, electrically conductive fluid comprises cooled electrically conductive fluid.
