Abstract
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 is positioned proximally of the first set of openings. First and second set of fluid delivery members are movably positioned in the elongated for delivering fluid to the lesion. An actuator moves the fluid delivery members from a retracted position within the elongated members to a first deployed position extending radially with respect to the elongated member and moves 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 are retained in the first and second deployed positions by a retention member.
