Embodiments of the present invention allow more full characterization of a stenotic lesion by measuring both pressure drop across the stenotic lesion and the size of the vessel lumen adjacent the stenotic lesion, both with sensors delivered intravascularly to the stenotic lesion site. In preferred embodiments, the size (e.g., inner diameter, cross-sectional profile) of the vessel lumen adjacent the stenotic lesion can be measured via one or more intravascular ultrasound transducers. In preferred embodiments, the intravascular ultrasound transducer(s) can be delivered to the site of the stenotic lesion with the same delivery device that carries the pressure transducer(s).

A sensor for a medical device including a plurality of sensor segments. Each of the plurality of sensor segments can include a layer of magnetically-permeable material and a layer of electrically-conductive material disposed on the layer of magnetically-permeable material. In an example, the layer of magnetically-permeable material can be arranged in a partially-annular shape. The sensor segments can include an electrical connection formation that extends transverse to the layers of magnetically-permeable material and electrically-conductive material. The electrical connection formation can be electrically coupled with the layer of electrically-conductive material. The plurality of sensor segments can be electrically coupled with each other through an electrical coupling of the respective layer of electrically-conductive material of each sensor segment with the electrical connection formation of another sensor segment.
