Abstract
Sensor delivery devices and methods of measuring Fractional Flow Reserve in a patient are disclosed. One sensor delivery device includes a distal sleeve, a proximal portion, and a pressure sensor. The distal sleeve is configured to be advanced through a patient's vasculature over a guidewire. The pressure sensor is located on the distal sleeve or the proximal portion. The pressure sensor is adapted to generate a signal proportional to fluid pressure. The pressure sensor includes a material having a low thermal coefficient of pressure.
