Abstract:
1. A tissue clamping device comprising first and second jaws having a longitudinal length movable between an open position for receiving tissue therebetween and a clamping position for compressing the tissue therebetween, the jaws each having a clamping surface and an ablation member in face to face relation with the clamping surface and ablation member of the other jaw; each ablation member being connectible to an ablation energy source for providing ablation energy to a selected ablation area between the jaws; said device further comprising at least one temperature sensor carried by one of the jaws, spaced laterally from the respective ablation member and adapted to sense the temperature of tissue at a selected location which selected location is in the vicinity of the respective clamping surface so that in the clamping position the temperature sensor monitors the temperature of tissue at said selected location to detect undesired thermal spread in the compressed tissue that is located outside the selected ablation area.
