Abstract

A medical device is provided having a means for actuating a pair of opposing jaw members. The jaw members are movable relative to one another from a first position, wherein the jaw members are disposed in a spaced apart relation relative to one another, to a second position, wherein the jaw members cooperate to grasp tissue therebetween. An ablation tool is connected to at least one of the jaws members, such that the jaw members are capable of conducting ablation energy through the tissue grasped therebetween.

Claims (16)

1. A medical device for ablating tissue comprising:

a shaft structure defining an insulating segment having a distal end;

a bellows portion having a first end and a second end; and

a cooling segment,

wherein the first end of the bellows portion is connected to the insulating segment distal end, and the second end of the bellows portion is connected to the cooling segment so that the insulating segment distal end and the cooling segment can be laterally juxtaposed, substantially parallel to each other in a single plane.

2. The medical device of claim 1 further comprising:

a handle connected to the insulating segment of the shaft structure.

3. The medical device of claim 2 further comprising:

a coolant injection tube for introducing coolant into the cooling segment.

4. The medical device of claim 2 further comprising:

an actuation assembly operably coupled to the shaft structure to move the cooling segment from a first position to a second position to create a tissue clamping region.

5. The medical device of claim 4 wherein the actuation assembly comprises:

a deflection mechanism; and,

a linkage assembly operatively coupled to the deflection mechanism wherein activation of the deflection mechanism displaces the cooling segment in a substantially a parallel orientation to the insulating segment to create the tissue clamping region.

6. The medical device of claim 4 wherein the linkage assembly is a pull wire.

7. The medical device of claim 4 wherein the cooling segment has additional insulation on an outward face.
