ABSTRACT:
A guiding catheter for use in medical procedures includes a flexible shaft with one or more audio transducers and a distal tip. An audio signal may be sent to one or more of the transducers and a reflected signal is received at one or more transducers. The reflected signal is used to detect the presence of an anatomical structure to assist in navigating the catheter to its destination. In another arrangement, the transducer can be used passively to detect physical characteristics of the heart such as sound, subsonic energy or temperature, that indicate relative proximity of a destination vessel.
