1. An intraluminal ultrasound imaging device, comprising:
a flexible elongate member configured to be positioned within a body lumen of a patient; and
an ultrasound imaging assembly coupled to a distal portion of the flexible elongate member and comprising:
a flexible substrate comprising a scanner body portion and an attachment portion extending proximally from the scanner body portion, wherein the attachment portion defines a curved path comprising a first curve curving in a first direction and a second curve curving in a different second direction;
one or more control circuits mounted on the scanner body portion;
one or more transducer elements mounted on the scanner body portion and in communication with the one or more control circuits; and
a plurality of conductive traces disposed on the attachment portion, wherein the plurality of conductive traces is in electrical communication with the one or more control circuits, wherein the plurality of conductive traces follows the curved path of the attachment portion, and wherein each conductive trace comprises a pattern that bends relative to the curved path of the attachment portion wherein the pattern of each conductive trace comprises a sinusoidal shape.
