IMPLANTABLE DOPPLER BLOOD FLOW MONITOR AND DOPPLER PROBE

摘要

A Doppler blood flow monitoring system comprises a sensor cuff capable of being secured around an exterior surface of a patient's vessel, at least one transducer attached to the sensor cuff for generating signals into the vessel and for receiving said signals, and a transmitter in communication with the at least one transducer and capable of wirelessly transmitting an RF signal external to the patient's body. The system also comprises a receiver capable of receiving the RF signal from the transmitter and being capable of generating an audible sound or signal commensurate with detected flow. The system can take advantage of pulse wave or continuous wave Doppler technology.
