Abstract
A device for ablating target tissue of a patient with electrical energy is provided. An elongate shaft includes a proximal portion and a distal portion, and a radially expandable element is attached to the distal portion. An ablation element for delivering electrical energy to target tissue is mounted to the radially expandable element. The device can be constructed and arranged to ablate the duodenal mucosa of a patient while avoiding damage to the duodenal adventitial tissue. Systems and methods of treating target tissue are also provided.
