Abstract
A cryoprobe clamp for creating a lesion in a target tissue comprises a housing portion, a handle extending from the housing portion, a clamp assembly including a distal blade and a proximal blade structured for clamping a target tissue therebetween, a trigger mechanism positioned adjacent the handle and operably coupled to the clamp assembly, and an ablation tool extending between the housing portion and the clamp assembly. The distal blade includes receiving means structured to receive a distal portion of the ablation tool, and the proximal blade includes an outer frame surrounding an open window portion. Upon clamping the target tissue between the distal and proximal blades, a lesion formed by the distal end of the ablation tool is visible through the window portion of the proximal blade.
