Abstract
A method for assessing functionality of a valve in a heart includes providing a position sensor that is a wireless transponder for transmitting or receiving an ultrasound wave for determination of position coordinates of the position sensor at the point; implanting the wireless transponder at a point on the valve; and using a position determining system for determining whether the valve is functioning properly based on position coordinates of the wireless transponder.
