摘要: A radio frequency generator for ablation, configured to deliver a direct current, an alternating current, and a radio frequency energy to a lesion for treating a pulmonary disease. The radio frequency generator for ablation can determine the ablation effectiveness according to one or more of a falling value of impedance, a change rate of impedance, the change in the change rate of impedance, or the change of impedance from falling to rising. According to the radio frequency generator for ablation, a segmentation control method and dynamic smoothing are used for adjusting a radio frequency output power to control an ablation temperature, and a tissue to be ablated is avoided being quickly heated in short time to ensure the smooth change in the radio frequency output power in the ablation process. The radio frequency generator for ablation further comprises a specific protection mechanism for preventing repeating ablation. A temperature of a site to be ablated is detected before each ablation is applied. If the temperature of the site to be ablated is higher than 40°C to 60°C, ablation is not started. Also disclosed is a multi-electrode ablation device including the radio frequency generator for ablation.

摘要: Disclosed herein are system and method for locating and identifying nerves innervating the wall of arteries such as the renal artery. The system identifies area on vessel wall innervated with nerves; provides indication on whether energy is delivered accurately to a targeted nerve; and provides immediate post-procedural assessment of the effect of energy delivered to the nerve. The method includes evaluating a change in physiological parameters after energy is delivered to arterial wall; and determining the type of nerve that the energy was directed to (sympathetic or parasympathetic or none) based on the evaluated results. The system includes at least a device (101) for delivering energy to the wall of blood vessel; sensor (103) for detecting physiological signals from a subject; and indicator (105) to display results obtained using said method. Also provided are catheters (2510, 2520) for performing the mapping and ablating functions.
