摘要：A method for delivering RF energy to living tissue includes the steps of
extending a guidewire to a tissue treatment site in a body. A controllable stiffnesscatheter is provided with a stiffness device having non-metallic properties and atemperature-changing device. The stiffness device is in a stiff state below a giventemperature and in a soft state above the given temperature. While supplying power tothe temperature-changing device, the catheter is threaded along the guidewire up to thetreatment site in the soft state. Power is removed from the temperature-changing deviceto alter the non-metallic properties of the stiffness device and directly result in a changeof the stiffness device to the stiff state without straightening the catheter. The RF energysupply device is physically contacted with the treatment site and RF energy is deliveredto the treatment site from the RF energy supply device.
