1. An apparatus, comprising:
an intravascular imaging catheter comprising:
a flexible elongate member sized and shaped for insertion into a vessel of a patient, wherein the flexible elongate member comprises:
an outer member comprising:
a distal portion terminating at a distal end; and
an outer surface;
an inner member positioned inside the outer member; and
a flex circuit positioned at the distal portion of the flexible elongate member,
wherein the flex circuit comprises a distal portion with a plurality of transducers and a proximal portion with a plurality of controllers in communication with the plurality of transducers,
wherein the flex circuit is positioned directly around the outer surface of the outer member such that the plurality of transducers is positioned proximate to the distal end of the outer member.
