摘要：
Method and systems for ablating nerves including measurement of physiological parameters and/or electrical conduction. The method may include ablating nerves within an artery of a patient such as the renal artery and may include advancing a catheter into the artery, measuring a physiological parameter, emitting an electrical pulse into a wall of the artery, measuring the physiological parameter during or after the step of emitting the electrical pulse, ablating the artery wall, then repeating the steps of measuring the physiological parameter, emitting an electrical pulse, and measuring the physiological parameter during or after the step of emitting the electrical pulse. The change in the physiological parameter caused by the electrical pulse before ablation may be compared to the change in the physiological parameter caused by the electrical pulse after ablation to determine the degree of nerve ablation achieved and whether or not to perform further ablation.
