Patent ID: 6989004

Claim:
A surgical apparatus for delivering fluid to treat a lesion comprising: an elongated member having a distal tip and a first and second set of openings formed in a sidewall proximal of the distal tip, the second set of openings being positioned proximally of the first set of openings; first and second fluid delivery members movably positioned in the elongated member, each of the fluid delivery members having a lumen and at least one opening communicating with the lumen for delivering fluid to the lesion; and an actuator operatively associated with the fluid delivery members, the actuator actuable to a first position to move the fluid delivery members from a retracted position within the elongated member to a first deployed position extending radially with respect to the elongated member, the actuator further actuable to a second position to move the fluid delivery members from the first deployed position to a second deployed position extending further radially from the elongated member, the fluid delivery members being retained in the first and second deployed positions by a first and second radially spaced ratchets.
