1. An intraluminal ultrasound device, comprising:
a flexible elongate member configured to be inserted into a lumen of a patient, the flexible elongate member comprising a proximal portion and a distal portion;
an ultrasound imaging assembly disposed at the distal portion of the flexible elongate member and configured to obtain imaging data while positioned within the lumen of the patient, the ultrasound imaging assembly having a proximal-most end;
a transducer; and
an intermediate member coaxially disposed around an exterior of the flexible elongate member and extending lengthwise along a length the flexible elongate member proximal from the proximal-most end of the ultrasound imaging assembly, the intermediate member being mechanically and acoustically coupled to the transducer,
wherein the intermediate member has a plurality of vibrational bands that are spaced apart along a length of the flexible elongate member proximally of the ultrasound imaging assembly, and a plurality of flexible connecting regions extending along the length of the flexible elongate member between respective adjacent pairs of the vibrational bands, the flexible connecting regions are more flexible than the vibrational bands, and the vibrational bands are configured to emit acoustic energy in response to the transducer for therapeutic treatment within the lumen of the patient.
