Embodiments of the present disclosure are related to intravascular devices having improved rapid-exchange configurations and associated systems and methods. In some particular embodiments, the devices of the present disclosure include a reinforced rapid-exchange port, an offset rapid-exchange port, and/or combinations thereof. For example, in some implementations an intravascular imaging device is provided that includes a main catheter body; a rotational imaging element positioned within a lumen of the main catheter body; a distal portion extending from the main catheter body, the distal portion having a rapid-exchange port in communication with a guidewire lumen, the rapid-exchange port and the guidewire lumen sized and shaped to receive a guidewire; and at least one reinforcing element positioned adjacent to the rapid-exchange port. |
