Abstract

Intraluminal ultrasound devices, systems and methods are provided. In one embodiment, an intraluminal ultrasound device includes a flexible elongate member configured to be positioned within a body lumen of a patient, the flexible elongate member including a distal portion and a longitudinal axis; and a transducer array disposed at the distal portion of the flexible elongate member and circumferentially positioned around the longitudinal axis of the flexible elongate member. The transducer array includes a plurality of micromachined ultrasound transducers (MUTs). In addition, the transducer array is configured to obtain ultrasound imaging data of the body lumen in response to a first electrical signal, and apply an ultrasound therapy within the body lumen in response to a second electricalsignal.

Description

technical field [0001] The present disclosure relates generally to intravascular ultrasound devices, and in particular to intraluminal ultrasound devices with ultrasound transducer arrays tunable for both imaging and therapeutic applications. Background technique [0002] Intravascular ultrasound (IVUS) imaging is widely used in interventional cardiology as a diagnostic tool for evaluating diseased blood vessels, such as arteries, in the human body to determine the need for treatment, guide intervention and / or assess its effectiveness. An IVUS device including one or more ultrasound transducers is delivered into the blood vessel and directed to the area to be imaged. The transducer emits ultrasound energy with a frequency above 10 MHz to create an image of the vessel of interest. Ultrasound is caused in part by discontinuous reflections from tissue structures (such as the various layers of blood vessel walls), red blood cells, and other features of interest. Echoes from th...
