ABSTRACT:
The present invention generally relates to medical devices, and more particularly to an improved medical imaging device. In one embodiment, an imaging device includes a drive shaft having proximal and distal ends received within the lumen; and an imaging transducer assembly coupled to the distal end of the drive shaft and positioned at the distal portion of the elongate member. The imaging transducer assembly includes one or more imaging transducers formed with a piezoelectric composite plate using photolithography based micromachining.
