摘要：
The invention relates to a pressure sensor catheter system and method for measuring the pressure difference based on the simultaneous acquisition of the pressure both on the proximal and distal side of a flow constriction, such as a stenosis, in a body lumen or measuring a distal pressure under influence of the flow constriction. The system comprises: - a shaft having an exterior wall, a distal tip and a proximal end； - a first pressure sensor positioned on the exterior of the shaft at the distal tip； - a second sensor placed on the exterior wall of the shaft at a distance proximal from the first sensor, Wherein the distal tip With the first pressure sensor has a narrower maximum outer diameter than the outer diameter of the shaft at the location of the second pressure sensor.The invention relates to a pressure sensor catheter system and method for measuring the pressure difference based on the simultaneous acquisition of the pressure both on the proximal and distal side of a flow constriction, such as a stenosis, in a body lumen or measuring a distal pressure under influence of the flow constriction.
