US Patent 7087040 Apparatus for delivering ablation fluid to treat lesions

A surgical apparatus for delivering fluid to treat a lesion comprising a housing, an elongated member extending from the housing, and a plurality of tines positioned in the housing. Each of the tines has a lumen and at least one opening communicating with the lumen for delivering fluid to the lesion. An actuator is operatively associated with the tines and actuable to a first position to move the plurality of tines from a retracted position substantially within the elongated member to a first deployed position extending from the elongated member and actuable to a second position to move the plurality of tines from the first position to a second deployed position.
