摘要：
An energy delivering probe is used for thermally coagulating and/or constricting hollow anatomical structures (HAS) including, but not limited to, blood vessels such as perforator veins. The probe includes a shaft and at least two electrodes where at least one of the electrodes has a perimeter that increases as it extends proximally.
