Abstract: An intravascular ultrasound probe is disclosed, incorporating features for utilizing an advanced transducer technology on a rotating transducer shaft. In particular, the probe accommodates the transmission of the multitude of signals across the boundary between the rotary and stationary components of the probe required to support an advanced transducer technology. These advanced transducer technologies offer the potential for increased bandwidth, improved beam profiles, better signal to noise ratio, reduced manufacturing costs, advanced tissue characterization algorithms, and other desirable features. Furthermore, the inclusion of electronic components on the spinning side of the probe can be highly advantageous in terms of preserving maximum signal to noise ratio and signal fidelity, along with other performance benefits.

Abstract: The present disclosure provides various embodiments of an ultrasound catheter for use in intravascular ultrasound (IVUS) imaging. An exemplary IVUS device includes an flexible elongate member having a lumen extending therethrough, and a rotatable imaging core disposed within the lumen. The imaging core is further configured to transmit and receive ultrasound signals through a distal portion of the flexible elongate member. The distal portion of the flexible elongate member includes a first set of material layers, while the proximal portion includes a second set of material layers different than the first set of material layers. The first set of material layers and the second material layers minimize distortion of the ultrasound signals. The first set of material layers further facilitates an average speed of sound through the first set of material layers that is substantially equivalent to a speed of sound through blood.
