Method for monitoring a physiologic parameter of patients with congestive heart failure

A method of monitoring one or more physiological parameters useful in diagnosing and/or treating a cardiovascular disease within a patient, the method comprising:

• providing a sensor comprising a hermetic sensor package containing at least one inductor coil and at least one sensing element operable to sense at least one physiological parameter of the patient, the sensor package having oppositely-disposed first and second portions;
• assembling the sensor with an anchoring mechanism to form an implantable sensing device, the anchoring mechanism comprising oppositely-disposed first and second foldable umbrella structures located adjacent the first and second portions, respectively, of the sensor package, the first and second foldable umbrella structures having vertices that face away from each other, the sensor being assembled with the anchoring mechanism so that the sensor package thereof is between the first and second foldable umbrella structures, the second foldable umbrella structure being smaller than the first foldable umbrella structure;
• implanting the sensing device by folding the first and second foldable umbrella structures of the anchoring mechanism, passing the first or second foldable umbrella structure through a septum of the heart of the patient to locate the second foldable umbrella structure within a cavity on the left side of the patient's heart, and expanding the first and second foldable umbrella structures to engage opposite sides of the septum, wherein the entire sensing device is within the heart, the sensor package is located in the septum and the at least one sensing element senses the at least one physiological parameter in the cavity, wherein the first foldable umbrella structure and the majority of the sensing device are located in the right side of the heart to minimize the risk of thrombogenicity;
• operating the sensor to produce an output based on the at least one physiological parameter within the cavity of the patient;
• coupling the sensor to a non-implantable readout device that is not implanted in the patient, the readout device comprising at least one inductor coil having telemetric means that receives the output of the sensor through the at least one inductor coil of the sensing device;
• and
• tailoring a medication treatment for treating the cardiovascular disease of the patient based on the output of the sensor.
