Patent ID: 8784310

Claim:
A leadless implantable vascular sensor, comprising: at least one fixation element configured to secure the vascular sensor within a blood vessel; a sensor module housing coupled to the fixation element and including: a sensor housing including a plurality of exterior surfaces defining an interior portion of the sensor housing; a power supply housing coupled to the sensor housing and containing an energy storage device; a pressure sensor disposed within the interior portion of the sensor housing, the pressure sensor configured to sense blood pressure data within the blood vessel; a first electrocardiogram sensing electrode disposed on an exterior portion of the sensor housing; a second electrocardiogram sensing electrode disposed on an exterior portion of the power supply housing; an insulative break disposed on at least a portion of at least one of the plurality of exterior surfaces of the sensor housing and electrically isolating the first electrocardiogram sensing electrode from the second electrocardiogram sensing electrode, the sensor module housing further comprising a pair of parallel and opposed ends, the pair of parallel and opposed ends comprising a first end disposed on the sensor housing and a second end disposed on the power supply housing, and a plurality of sides disposed between the first end and the second end and including the plurality of exterior surfaces of the sensor housing, wherein: the first electrocardiogram sensing electrode is disposed on the first end; and the second electrocardiogram sensing electrode is disposed on the second end; the first and second electrocardiogram sensing electrodes configured to sense cardiac electrical data within the blood vessel; and circuitry means for processing the cardiac electrical data and blood pressure data sensed by the electrocardiogram sensing electrodes and pressure sensor to correlate the timing of the blood pressure data with a timing of a cardiac cycle.
