Abstract
A surgical device includes an elongated shaft having first and second electrically isolated electrodes coupled to the shaft such that an exposed portion of the second electrode is disposed around only part of a circumference of the elongated shaft, and includes a portion that is spaced proximally from the first electrode. Another surgical device also includes an elongated shaft having first and second electrically isolated electrodes coupled to the shaft, wherein the shaft includes a first side, and exposed surfaces of the first and second electrodes are side-facing toward the first side. Various embodiments of a 'cool back' are provided, allowing arthroscopic surgery on a first side of a device without tissue effects on a back side of the device.
