Patent Images
1. A system for monitoring blood pressure of a patient, comprising:
- an in-vivo sensor assembly configured for implantation beneath the skin of the patient, the sensor assembly configured to resonate at a frequency corresponding to a physiological blood pressure of a patient, the sensor assembly comprising a unitary hermetic housing that encloses a variable capacitor and an inductor within an interior chamber of the housing, wherein the variable capacitor and inductor is configured to emit a return signal when subjected to a burst of RF energy; and
an external electronics assembly configured to selectively energize the sensor assembly to affect the wireless monitoring of the blood pressure of the patient.
