ABSTRACT:
A method and apparatus for determining an angioplasty induced blood flow changes, wherein the apparatus includes the catheter having a port for introducing a blood property change in a downstream sensor. The downstream sensor and the catheter are configured to space the sensor from an adjacent vessel wall so as to minimize effects of the vessel wall during sensing of the blood property change.
