Method of manufacturing a rotational intravascular ultrasound probe

A method of manufacturing a rotational intravascular ultrasound probe for insertion into a vasculature, the method comprising:

• providing an injection mold having a recess in communication with a channel;
• providing an intravascular ultrasonic transducer for obtaining an intravascular image through rotation, the transducer including a front layer, a back layer, and a sacrificial layer disposed over the front layer, the transducer being coupled to a wire;
• disposing the transducer within the recess;
• disposing the wire within the channel;
• sliding a drive cable over the wire into the channel;
• injecting a material into the recess and the channel to form a transducer housing attached to the transducer and the drive cable;
• and
• removing the sacrificial layer after the transducer housing is formed.
