Abstract
An intravascular element, for example a guidewire, configured for pressure measurements and imaging within a patient. In an embodiment, the invention uses a system of optical fibers and photoabsorptive and/or photoreflective materials to make intravascular ultrasound (IVUS) measurements. In an embodiment, the invention uses microfabricated pressure sensors to measure fluidic pressure adjacent to the element, such as the pressure of the blood within the vasculature. In a clinical setting, the invention can provide a surgeon with critical information about pressure, tissue composition, and luminal area while also reducing the time for procedures.
