Abstract:
A blood pressure monitoring system, said system arranged to be used in a living being, the being having a blood vessel in which blood flows and which exhibits a pressure, said system being arranged for monitoring the blood pressure within the blood vessel of the living being and comprising a passive sensor unit and an associated energy application unit, said sensor unit being adapted to be implanted within the body of the being, said energy application unit being adapted to be located externally of the body of the being for wireless transmission of energy waves to said sensor unit, said sensor unit being constructed to at least partially surround the wall of the blood vessel to cause a first portion of the blood vessel to assume a flat shape and to enable the flat shaped portion of the blood vessel to move to a position in response to the blood pressure within the blood vessel, said sensor unit operating in response to said energy applied to said sensor unit by said externally located energy application unit to provide a wireless output signal indicative of the position of the flat shaped portion of the blood vessel, whereupon the blood pressure within the blood vessel may be determined.
