INTRAVASCULAR PRESSURE SENSOR CALIBRATION

摘要

The invention is a method for calibrating an intravascular pressure sensor at the point of use. By using data from a secondary pressure measurement device, e.g., an automated aortic pressure monitor, the pressure sensor can be easily calibrated over a range of temperatures and pressures relevant to the patient. Accordingly, an intravascular pressure sensor can be calibrated without undergoing a factory calibration. Additionally, in the event that the calibration is lost, the sensor can be recalibrated.

1. A method of calibrating an intravascular pressure sensor comprising:
providing an intravascular device comprising a pressure sensor, said intravascular device being operatively connected to a controller; providing pressure data to the controller from a pressure monitor that is monitoring a vascular pressure of a patient; inserting the intravascular pressure sensor into the vasculature of the patient; and causing the controller to calibrate a reading from the pressure sensor with the pressure data from the pressure monitor.
