Claim 14:
15. A method for evaluating a blood vessel and delivering a therapy to a treatment site of the blood vessel, the method comprising:
providing a catheter system comprising:
an elongate body comprising a distal portion, wherein the elongate body is insertable into the body lumen until the distal portion of the elongate body is distal to the treatment site, the elongate body defining a central lumen and a plurality of delivery lumens configured to encircle the central lumen on the distal portion of the elongate body; and
an inner member moveably disposed within the central lumen, the inner member comprising a body with an energy source disposed within the body, the energy source being configured to deliver therapeutic energy to the treatment site when the inner member is inserted into the central lumen of the elongate body; and
an imaging assembly located on the distal portion of the elongate body and on an exterior of the body of the inner member;

initially introducing the elongate body of the catheter system into the blood vessel and advancing the elongate body until the imaging assembly is distal to the treatment site;
imaging biological material within the blood vessel with the imaging assembly; and
delivering, with the energy source, therapeutic energy to the biological material, wherein the imaging assembly is configured to image the treatment site from inside the blood vessel while the therapeutic energy is delivered to the treatment site.
