    Abstract: A microwave ablation device for treating tissue includes an inner conductor having a length and a distal end and configured to deliver energy, a wire extending adjacent the inner conductor and axially translatable relative thereto, the wire including a length and a distal end, a distal tip disposed in mechanical cooperation with the distal end of the inner conductor and the distal end of the wire, and an outer conductor including a distal end and defining a longitudinal axis, the outer conductor at least partially surrounding the inner conductor and the wire at least partially along their lengths. The distal tip is movable substantially along the longitudinal axis with respect to the outer conductor and relative movement of the distal tip towards the distal end of the outer conductor causes at least a portion of the inner conductor to move away from the longitudinal axis.

    Abstract: An electrosurgical surface treatment formed on the surface of a surgical device the surface treatment including a indentation extending into a surface of the surgical device, the indentation including a first surface forming a first plane a second surface forming a second plane, and a third surface forming a third plane. The first, second and third planes are substantially perpendicular to each other. The surface treatment is visible to an ultrasonic imaging system and the surface treatment improves visibility of the surgical device by the ultrasonic imaging system.
