Abstract
A rotational intravascular ultrasound probe for insertion into a vasculature and a method of manufacturing the same. The rotational intravascular ultrasound probe comprises an elongate catheter having a flexible body and an elongate transducer shaft disposed within the flexible body. The transducer shaft comprises a proximal end portion, a distal end portion, a drive shaft extending from the proximal end portion to the distal end portion, an ultrasonic transducer disposed near the distal end portion for obtaining a circumferential image through rotation, and a transducer housing molded to the drive shaft and the ultrasonic transducer.

A method of manufacturing a rotational intravascular ultrasound probe for insertion into a vasculature, the method comprising:
- providing an injection mold having a recess;
- providing an ultrasonic transducer for obtaining a circumferential image through rotation, the transducer being coupled to a wire;
- disposing the transducer within the recess;
- placing a drive cable over the wire;
- and
- injecting a material into the injection mold to form a transducer housing attached to the transducer and the drive cable.
