Abstract: Provided is a medical device comprising an inner tubular member, an outer tubular member having a distal end and an open window disposed at the distal end, a first electrode and/or a second electrode disposed at the distal end of the outer tubular member, and a cannulated plunger or armature or shaft configured to drive the inner tubular member to cut tissue in cooperation with the open window of the outer tubular member wherein the first electrode and the second electrode are configured to provide RF energy needed for surgical operation and wherein the first and the second electrodes may be configured to be symmetrical or substantially symmetrical along a longitudinal axis of the outer tubular member or wherein the first electrode is configured to cover the open window of the outer tubular member and extended to one side of the outer tubular member and the second electrode is configured to be disposed on the other side of the outer tubular member. Also provided are methods of making a medical device as described herein.

Abstract: An electrosurgical device is provided. The electrosurgical device can include an elongated member configured to be attached to an elongated shaft of an endoscope, the elongated member including a distal portion that, when axially extended beyond a distal end of the shaft, bends toward a longitudinal axis of the shaft. The electrosurgical device can include an electrode exposed at the distal portion of the elongated member. The electrosurgical device can include an electrical interconnect coupling the electrode to an electrosurgical energy connection at a proximal portion of the elongated member.
