Rolled flexible substrate with integrated window for intraluminal ultrasound imaging device

An intraluminal ultrasound imaging device, comprising:

• a flexible elongate member configured for insertion into a body lumen of a patient, wherein the flexible elongate member comprises a proximal portion and a distal portion;
• and
• an ultrasound scanner assembly disposed at the distal portion of the flexible elongate member,
• wherein the ultrasound scanner assembly comprises a flexible substrate extending a width that is parallel to a central axis of the flexible substrate, comprising:
• a transducer region,
• a first control region, and
• a second control region,
• wherein, in a flat configuration, the first control region, the second control region, and the transducer region are arranged adjacent and laterally along the central axis,
• wherein the transducer region, the first control region, and the second control region are configured to transition from the flat configuration to a rolled configuration,
• wherein, in the rolled configuration:
• the first control region and the second control region form a first layer and the transducer region forms a second layer that is radially positioned around the first layer to comprise a tube shape and define a lumen configured to receive a guidewire.
