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.
