Abstract
An intravascular sensor assembly including a flexible elongate member having a longitudinal axis (LA) is provided. The sensor assembly includes a first engagement feature proximal to a distal end of the flexible elongate member; a core member disposed inside a lumen of the flexible elongate member, the core member configured to translate within the flexible elongate member along the LA proximal to the first engagement feature; and a component holding a sensor circuit, the component fixedly secured to a distal end of the core member such that the mounting structure translates along the LA of the flexible elongate member with the core member. A system and a method for performing measurements using a sensor as above are also provided.
