Patent ID: 7615010

Claim:
A system for monitoring one or more physiological parameters for diagnosis of congestive heart failure within a patient, said system comprising: at least one sensing device adapted to be implanted in a septum of the patient's heart and monitor said one or more physiological parameters within a heart cavity, said sensing device comprising an anchoring mechanism, at least one inductor coil and at least one sensor, with optional electronic components, said anchoring mechanism comprising first and second portions that are separated by the sensor and are both foldable and expandable, the first portion being adapted to pass through an opening of the septum and expand on a distal side thereof within the heart cavity, the second portion being adapted to expand on an oppositely-disposed proximal side of the septum, the first and second portions being configured to clamp the septum therebetween, said sensor being disposed relative to the anchoring mechanism so that when said sensing device is implanted in the septum from the proximal side thereof and said sensor is within the opening in the septum, the first portion of the anchoring mechanism and a majority of said sensing device are located on the proximal side of the septum, said sensing device has minimum protrusion in the heart cavity on the distal side of the septum to minimize the risk of thrombogenicity, and said sensor is configured to monitor the one or more physiological parameters within the heart cavity; a pacing/ICD unit for interrogating said at least one sensing device; an external unit for powering said at least one sensing device; and a non-implantable readout device that is not adapted to be implanted in the patient, said readout device comprising at least one inductor coil having telemetric means for at least one of electromagnetic telecommunication and electromagnetic wireless powering of said sensor through said at least one inductor coil of said sensing device.
