Patent ID: 7611455

Claim:
A device comprising: an arm comprising a first lumen; a member attached to the arm by a movable joint that permits the member to be placed in a desired orientation with respect to the arm, the member having a suction port comprising a suction aperture, wherein the port has a first diameter and the aperture has a second diameter, the first diameter being greater than the second diameter, and wherein the port is positioned on a surface of the member, a second lumen in fluid communication with the suction port and the first suction lumen, wherein suction to the second lumen is communicated to the suction port and at least one electrode; and a pulse generator coupled to the at least one electrode, wherein the joint comprises a proximal end, a distal end, and a plurality of links are free to move relative to one another so that the arm articulates, a cable extending through the links, wherein the cable comprises a distal end and a proximal end, and a locking actuator coupled to the proximal end of the cable and the proximal end of the arm to tension the cable thereby locking the links relative to one another so that the arm changes from an articulating condition to a locked rigid condition.
