A device, system, and method provides for removing deleterious tissue from healthy body tissue at a site inside a patient. The device includes a steerable electrosurgery device having a electrode to cut a core through tissue, including tissue surrounding a perimeter of the deleterious tissue, and has a lumen for aspirating the cored tissue from the patient. The electrode may form a closed loop, and may be the active electrode of an electrosurgery system. Further, the electrode may have a narrow profile. In addition, the electrode may be arranged to coagulate the cut tissue. The system includes the device and a seal to limit air leaks and bleeding resulting from the removal of cored tissue.
