Claim Text:
1. A medical device for manipulation of tissue of a patient, the medical device comprising: a shaft having a proximal section extending to a distal section that has a closed distal end portion, the shaft having a plurality of lumens formed therein including a first lumen for distally advancing a first reactant through the proximal section and a second lumen for distally advancing a second reactant through the proximal section; and a cannula passed through the shaft adjacent to the first and second lumens, the cannula having an outer wall, the cannula defining a longitudinal axis therethrough, the cannula comprising a flattened distal portion, the distal portion being twisted such that the outer wall forms a mixing element positioned longitudinally within the shaft and distally from the first and second lumens, the cannula comprising a third lumen therethrough, the third lumen being coincident with the longitudinal axis throughout the distal portion, the mixing element in fluid communication with the first and second lumens and having a series of baffles for mixing the first and second reactants together producing a reaction product to heat the closed distal end portion of the shaft for manipulation of the tissue.
