摘要：
An intravascular sensor delivery device for measuring a physiologicalparameter of a patient, such as bloodpressure, within a vascular structure or passage. In some embodiments, thedevice can be used to measure the pressure gradient acrossa stenotic lesion or heart valve. For example, such a device may be used tomeasure fractional flow reserve (FFR) across a stenoticlesion in order to assess the severity of the lesion. The sensor deliverydevice has a distal sleeve configured to pass or slide over astandard medical guidewire. Some distance back from the sensor and distalsleeve, the device separates from the guidewire topermit independent control of the sensor delivery device and the guidewire.The sensor delivery device can be sized to pass overdifferent sizes of guidewires to enable usage in coronary and peripheralarteries, for example.
