Abstract
An echogenic electrosurgical device and a method for electrosurgically treating a target site are provided. The device includes an elongate body having a proximal portion and a distal portion. The distal portion of the elongate body includes an echogenic region, a coated portion providing an electroinsulative layer and an uncoated electroconductive electrosurgical region. The coating allows reflection of ultrasonic waves from the coated echogenic region sufficient for ultrasonic imaging of the echogenic region at a resolution providing for effective navigation in a body. The coated region has a first surface area and the electrosurgical region has a second surface area. The first surface area is greater than the second surface area.
