15. A medical apparatus comprising:
a catheter comprising a proximal end region and a distal end region, wherein the proximal end region includes a handle assembly, and wherein the distal end region defines an elongate shaft terminating at a distal tip, the distal tip defining a side opening,
a transducer assembly positioned within the distal tip such that an ultrasonic transducer is exposed through the side opening, the transducer assembly comprising:
a substrate including a width, a length, and a longitudinal axis extending the length of the substrate bisecting the width, wherein the ultrasonic transducer positioned along the width of the substrate on a first side of the longitudinal axis, and
an ASIC chip and a capacitor positioned side-by-side along a second side of the longitudinal axis, wherein the substrate is folded along the longitudinal axis to position the ultrasonic transducer over the ASIC chip and capacitor.
