Abstract
Intravascular devices, systems, and methods are disclosed. In some embodiments, the intravascular devices include at least one pressure sensing component within a distal portion of the device. In that regard, one or more electrical, electronic, optical, and/or electro-optical pressure-sensing components is secured to an elongated substrate such that the pressure-sensing component is mounted perpendicular to a central longitudinal axis of the device. In some implementations, the elongated substrate has a cylindrical profile. Methods of making, assembling, and/or using such intravascular devices and associated systems are also provided.
