| 1. A therapeutic device for treating a living tissue, comprising:
a pair of openable/closable elongate holding portions relatively rotatable about a lateral axis, the holding portions being
configured to hold the living tissue therebetween, each having proximal and distal ends, and extending in a lengthwise direction
normal to the lateral axis;
an elongate heating portion provided for at least one of the holding portions and configured to treat the living tissue, the
heating portion extending in the lengthwise direction between the proximal and distal ends of the holding portion, the heating
portion having an elongate treatment surface which is contacted with the living tissue along the lengthwise direction; and
a plurality of heat generators arranged in the heating portion in the lengthwise direction, such that each heat generator
of the plurality of heat generators is independently controllable to maintain a desired temperature profile along the lengthwise
direction for the treatment surface of said heating portion, by generating heat and transmitting the heat to the living tissue
through the treatment surface, the heating portion being electrically insulated from the heat generators.
