Abstract
An intravascular sensor delivery device for measuring a physiological parameter of a patient, such as blood pressure, within a vascular structure or passage. In some embodiments, the device can be used to measure the pressure gradient across a stenotic lesion or heart valve. The sensor delivery device can be sized to pass over different sizes of guidewires to enable usage in coronary and peripheral arteries, for example.
Claims20
A method comprising:
- inserting a guidewire into the anatomical structure of a patient;
- sliding a sensor delivery device over the guidewire to a location of interest within an anatomical structure of the patient, wherein the location of interest comprises a stenotic lesion, and the sensor delivery device includes a first sensor configured to measure a physiological parameter of the patient,
- measuring, with the first sensor, the physiological parameter of the patient on a first side of the stenotic lesion during a diastolic phase of at least one cardiac cycle,
- measuring, with a second sensor, the physiological parameter of the patient on a second side of the stenotic lesion during the diastolic phase of at least one cardiac cycle,
- calculating a numerical value based on the physiological parameter measured by the first sensor and the physiological parameter measured by the second sensor;
- and
- providing the numerical value to evaluate the anatomical structure.
