Abstract
An intravascular sensor delivery device for measuring a physiological parameter of a patient, such as blood pressure, within a vascular structure or passage. In some embodiments, the device can be used to measure the pressure gradient across a stenotic lesion or heart valve. For example, such a device may be used to measure fractional flow reserve (FFR) across a stenotic lesion in order to assess the severity of the lesion. The sensor delivery device has a distal sleeve configured to pass or slide over a standard medical guidewire. Some distance back from the sensor and distal sleeve, the device separates from the guidewire to permit independent control of the sensor delivery device and the guidewire. The sensor delivery device can be sized to pass over different sizes of guidewires to enable usage in coronary and peripheral arteries, for example.

fluid tubing adapted to provide fluid communication between the injection system and a patient;
a control panel; and a processor;
wherein the processor is adapted to receive:
(a) a first signal representative of blood pressure measured upstream of a location of interest in the patient, and (b) a second signal generated by a sensor delivery device, the second signal representative of blood pressure measured downstream of a location of interest in the patient, and wherein the control panel is adapted to display information derived from the first and second signals.
fluid tubing adapted to provide fluid communication between the injection system and a patient;
