Abstract

A medical device having an implantable instrument configured to be implanted in bone tissue, the implantable instrument having an internal chamber configured to house at least one transducer; a transducer located within the internal chamber of the implantable instrument, the transducer configured to transmit a signal and to receive one or more reflections of that signal; and a signal processing system configured to process the signals transmitted and received by the transducer so as to provide information indicative of the acoustic impedance of matter in the vicinity of the implantable instrument after it is implanted into the bone tissue based on the signals transmitted and received by the transducer.
