| 1. An implantable system comprising:
an implantable housing;
a plurality of implantable sound-detecting sensors adapted to be positioned in a spaced-apart configuration with each implantable
sensor at a different location adjacent to a pulmonary system and further adapted to output signals indicative of lung-sounds,
at least one of the plurality of implantable sound-detecting sensors located external of the implantable housing;
at least one wireless transmitter in communication with at least one of the plurality of implantable sound-detecting sensors
and configured to wirelessly transmit the lung sound-signals output by the at least one implantable sound-detecting sensor;
and
a controller adapted to monitor the lung-sound signals.
