Abstract:
An implantable biosensor system for monitoring a physiological condition in a patient, the biosensor system comprising:(a) at least one sensor for sensing at least one parameter of a physiological condition and for generating an electrical sensor signal representative of the physiological condition; and (b) at least one first acoustic activatable transducer being directly or indirectly coupled with said at least one sensor, said at least one first acoustic activatable transducer being for converting a received acoustic interrogation signal from outside the patient's body into an electrical power for energizing said at least one sensor, said at least one first acoustic activatable transducer further being for converting said electrical sensor signal of said at least one sensor into an acoustic signal receivable out of the patient's body, such that information pertaining to said at least one parameter of the physiological condition can be relayed outside the patient's body upon generation of an acoustic interrogation signal.
