Abstract: Provided herein is a catheter assembly including an imaging device for identifying an anatomical structure. The catheter assembly includes a patient cannula configured to be drawn along a catheter or guide wire; a transseptal puncture catheter at least partially enclosed within the patient cannula; and an imaging catheter. The imaging catheter includes a transducer configured to emit an energy beam capable of reflecting from an anatomical structure and to detect energy reflected from the structure. The catheter assembly also includes a transmitter for conveying a signal representative of the detected energy from the transducer to a signal processor for obtaining information about the structure. An imagining system and a method for identifying a predetermined transseptal puncture location on an atrial septum are also provided herein.
