ABSTRACT:
A surgical apparatus for delivering fluid to treat a lesion comprising an elongated member having a distal tip and a plurality of slots formed in a sidewall proximal of the distal tip, a plurality of fluid delivery members positioned in the elongated member and having a lumen and at least one opening communicating with the lumen for delivering fluid to the lesion, and an actuator actuable to a first position to move the plurality of fluid delivery members from a retracted position within the elongated member to a first deployed position extending radially with respect to the elongated member and actuable to a second position to move the plurality of fluid delivery members from the first position to a second deployed position extending further radially from the elongated member.
