摘要：
An intravascular sensor delivery device for measuring a physiologicalparameter of apatient, such as blood pressure, within a vascular structure or passage. Insomeembodiments, the device can be used to measure the pressure gradient across astenoticlesion or heart valve. For example, such a device may be used to measurefractional flowreserve (FFR) across a stenotic lesion in order to assess the severity of thelesion. The sensordelivery device has a distal sleeve configured to pass or slide over astandard medicalguidewire. Some distance back from the sensor and distal sleeve, the deviceseparates fromthe guidewire to permit independent control of the sensor delivery device andthe guidewire.The sensor delivery device can be sized to pass over different sizes ofguidewires to enableusage in coronary and peripheral arteries, for example.
