Claim Text:
1. A tissue treatment device, comprising: a power source; an elongate shaft having a distal end; a heating element disposed at the distal end of the shaft, the heating element having a proximal end and a distal end; a first electrical pathway configured to extend between the power source, the proximal end of the heating element, and the distal end of the heating element, and defining a first treatment length extending between the proximal and distal ends of the heating element; a second electrical pathway configured to extend between the power source, the distal end of the heating element, and an intermediate point along the heating element intermediate the proximal and distal ends thereof, and defining a second treatment length extending between the intermediate point and the distal end of the heating element, wherein the intermediate point is offset from a lengthwise center of the heating element; and a third electrical pathway configured to extend between the power source, the proximal end of the heating element, and the intermediate point along the heating element, and defining a third treatment length extending between the intermediate point and the proximal end of the heating element, wherein each of the first treatment length, the second treatment length, and the third treatment length is different, wherein the power source is configured to automatically determine the treatment length of the electrical pathway to which the power source is electrically connected and adjust a level of power delivery for a desired energy output based on the treatment length of the electrical pathway to which the power source is electrically connected.
