Classification: CPC A  G | IPC A

Claim 3:
4. A medical device, comprising:
an ultrasound transducer comprising elements configured to transmit nonparallel ultrasound beams toward a blood vessel and to detect reflections of the nonparallel ultrasound beams from the blood vessel; and
a processor configured to:
determine changes in slant ranges at portions of a wall of the blood vessel by analyzing the reflections of the nonparallel ultrasound beams from the blood vessel;
determine a pulse wave velocity of the blood vessel by determining a time period between the determinations of the changes in the slant ranges at the portions of the wall of the blood vessel; and
determine a blood pressure of the blood vessel by multiplying the pulse wave velocity with a velocity of blood flowing through the blood vessel.
