ABSTRACT:
A catheter apparatus for monitoring cardiovascular function is provided. The catheter apparatus contains an elongated body having proximal and distal ends; a phased-array ultrasonic transducer; and an electrical conductor. The phased-array ultrasonic transducer is mounted proximate the distal end of the catheter body to transmit ultrasound and receive resultant echoes so as to provide a field of view within which flow rates can be measured and features imaged. The electrical conductor is disposed in the catheter body for electrically connecting the transducer to control circuitry external of the catheter.
