Abstract
A method and system are provided for determining a pressure associated with a lumen of a patient. A wireless sensor is positioned in the lumen of the patient. The sensor has a body with a pressure sensitive surface, including a sealed cavity that holds an inductive-capacitive (LC) resonant circuit. A capacitance of the LC resonant circuit is configured to vary in response to changes in pressure in the lumen. The LC resonant circuit has a charge time related to a quality factor (Q) of the LC resonant circuit. The LC resonant circuit is energized with an energizing signal during a measurement cycle. The energizing signal has a duty cycle with an on-time that is set, in part, based on the charge time. A ring down response is received from the wireless sensor. The ring down response is utilized to calculate the pressure associated with the lumen of the patient.
