Abstract

An apparatus for use in cannulation of blood vessels which includes an ultrasonic flow sensing assembly. The assembly includes inner and outer elongated electrically conducting tubular members which are separated by an electrical insulator. A
piezoelectric transducer capable of generating and receiving ultrasonic waves is located at the distal ends of the tubular members and is electrically connected to them. A power source is applied to the tubular members and to the piezoelectric transducer such that when a hollow needle containing the ultrasonic flow sensing assembly is advanced through tissue, emitted and detected ultrasonic waves can be employed to locate body vessels which can then be penetrated by the sharpened end of the hollow needle.
