Abstract:
A implantable medical device system for measuring barometric pressure within a patient's body and for measuring absolute cardiac pressure within the patient's heart comprising:an implantable medical device for powering an absolute pressure sensor and for processing absolute cardiac pressure signal values and for powering a barometric pressure sensor and for processing barometric pressure signal values;an implantable absolute pressure sensor adapted to be located in a pressure measurement site of the patient's heart coupled with said implantable medical device for deriving and providing absolute cardiac pressure signal values to said implantable medical device for processing;lead means for coupling said implantable absolute pressure sensor with said implantable medical device for providing power to said absolute pressure sensor and for conveying absolute cardiac pressure signal values to said implantable medical device; andan implantable barometric pressure sensor adapted to be located at a site removed from the patient's heart that is not affected by cardiac pressure for deriving and providing barometric pressure signal values to said implantable medical device for processing in conjunction with said absolute cardiac pressure values.
