Abstract:
A body implantable dual transducer apparatus comprising:a first sensor that senses a first physiologic parameter and provides a first sensor signal when powered by a supply voltage of a first polarity;a second sensor that senses a second physiologic parameter and provides a second signal when powered by a supply voltage of a second polarity;a pair of conductors coupled to the first and second sensors;a control unit that selectively applies the supply voltage of either the first polarity or the second polarity across the pair of conductors; andswitching circuitry that, in response to the supply voltage of the first polarity, provides the supply voltage of the first polarity to the first sensor for generating the first sensor signal, and in response to the supply voltage of the second polarity, provides the supply voltage of the second polarity to the second sensor for generating the second sensor signal, the first and second sensor signals being transmitted to the control unit using the pair of conductors wherein at least one of the sensors senses a plurality of different physiological parameters.
